5G United States eSIM | AT&T, Verizon & T-Mobile
Roami
Roami is a global eSIM carrier focused on travel connectivity. This guide is compiled from network data, official carrier and manufacturer documentation, and traveler inquiries.
📑 Table of Contents
Choosing a United States eSIM is choosing how far you will drive: three national networks split coverage, speed and city depth across a continent-sized map, and this guide matches them to your route. The three US national networks are not interchangeable, and in a country this wide the right one depends almost entirely on your route. On Ookla’s 2H 2025 United States report, T-Mobile was the Best Mobile Network overall and the Best 5G Network, with the highest Speed Score (73.26) and the widest 5G availability (91.2%). Verizon won Best Mobile Coverage, posting a Coverage Score of 30.0% — the most geographic reach of the three. AT&T sat between them on most measures and led on the fixed broadband side. So the carrier that suits you is a question of geography: dense metros reward one network, long rural drives reward another. We can name the source behind every statement — see the list at the bottom before spending on the United States.
Quick answer: T-Mobile leads this comparison on raw speed and 5G, Verizon on geographic coverage — and which one wins depends on your route. The tables below show where that flips. You can also try the setup first-hand with Roami’s free Roami trial.
One prerequisite worth ten seconds of your time: confirm your handset is eSIM-capable via the phone compatibility list, and skim how eSIM installation works if the process is new to you.
The short version: Staying in New York, Los Angeles or Chicago? T-Mobile is the fastest network and holds 5G almost everywhere (91.2% availability). Driving national parks or rural Midwest? Verizon has the widest geographic footprint. Want a clean prepaid eSIM as a visitor? T-Mobile sells a tourist eSIM with no ID and no US address, while AT&T and Verizon point you at their prepaid brands Cricket and Visible. Or skip the paperwork: free test eSIM tests the networks at no cost, and code WEB20 knocks 20% off United States prepaid eSIM plans.
What are your United States eSIM options?
T-Mobile, Verizon and AT&T head to head
| T-Mobile | Verizon | AT&T | |
|---|---|---|---|
| Tourist prepaid eSIM | Yes, through the T-Mobile Prepaid tourist eSIM and US Pass plans | Yes, through Verizon prepaid eSIM and the Visible brand | Yes, through AT&T prepaid eSIM and the Cricket brand |
| Signature strength | Best Mobile Network and Best 5G (Ookla); fastest Speed Score and highest 5G availability | Best Mobile Coverage; strongest geographic reach, especially rural and interstate | Solid all-round coverage; best fixed broadband backbone |
| Lowest-cost prepaid start | US Pass: 30 days unlimited talk, text and data from $50, no ID | Visible: unlimited from $25 per month | Cricket: 5 GB for $30 per month |
| Visitor buying process | ★★★ — download the app, activate after you land, no paperwork | ★★ — online sign-up, no store visit, prepaid eSIM only | ★★ — prepaid eSIM online, or Cricket eSIM with no credit check |
The last row decides most visitor trips: all three national carriers now sell a prepaid eSIM that an international visitor can use, but none of them wants you walking into a postpaid store with a passport and leaving with a plan the same afternoon. T-Mobile is the friendliest route because it built a tourist eSIM product on purpose. Verizon and AT&T route most visitor interest to their prepaid brands — Visible for Verizon, Cricket for AT&T — which is actually the easier path.
The US MVNO tier: Cricket, Visible, Tello, Google Fi and the rest
America’s MVNO layer — brands that buy airtime from T-Mobile, Verizon or AT&T instead of owning towers — is where a visitor finds the least friction: app-only sign-up, no credit check and often no store visit at all. US Cellular is the exception, a genuine regional network rather than a reseller.
| Virtual brand | Host network | eSIM support | Best for |
|---|---|---|---|
| Cricket Wireless | AT&T | Yes, eSIM supported with no credit check | Visitors who want AT&T coverage without AT&T paperwork |
| Visible | Verizon | Yes, eSIM, online only | Budget travelers who want Verizon coverage and never plan to visit a store |
| Metro by T-Mobile | T-Mobile | Yes, but activation requires you to be physically in the US | Longer stays where you already landed and have a US payment method |
| Mint Mobile | T-Mobile | Yes, eSIM, activated in the app | Visitors comfortable buying multi-month upfront and using international cards via a partner |
| US Cellular | Own network (mostly rural) | eSIM on newer plans | Anyone spending real time in the Mountain West and Pacific Northwest interior |
| Tello | T-Mobile | Yes, eSIM activated in the app or on the web | Light data users who want to build their own monthly allowance |
| Google Fi | T-Mobile, with US Cellular roaming | Yes, eSIM, but you need a Google account | A single line that keeps working when the trip spills into Canada or Mexico |
| Ultra Mobile | T-Mobile | Yes, eSIM, online sign-up | Calling home often — international minutes are part of the plan |
| Straight Talk | Verizon | Yes, eSIM, no credit check | Picking Verizon coverage up off a Walmart shelf |
| US Mobile | Verizon or T-Mobile, chosen at signup | Yes, eSIM, and the network can be swapped later | Anyone who wants to pick the network instead of inheriting one |
| Boost Mobile | AT&T | Yes, eSIM, online only | AT&T coverage at the budget end of the market |
| Xfinity Mobile | Verizon | Yes — BYOD eSIM is installed from inside the Xfinity app | Comcast households only: residential Xfinity Internet is a precondition, and a $25 one-time activation fee applies per line |
| Spectrum Mobile | Verizon | Yes, on iPhone 12 and newer, the Galaxy S24 series and recent iPads | Spectrum Internet households, where the first unlimited line is bundled with the broadband plan |
| H2O Wireless | AT&T | Yes, eSIM activation for compatible BYOD handsets, and the eSIM itself is free | AT&T coverage with heavy international calling; a shipped physical SIM costs $3, the eSIM costs nothing |
| Tracfone | Verizon | Yes, but only on iPhone 12 through 16 and iPhone SE (3rd gen) | Pay-as-you-go buyers who already own one of those iPhones — Android eSIM is not on Tracfone’s list |
| Total Wireless | Verizon | Yes, on iPhone 12–16, iPhone SE (3rd gen) and Galaxy S24 models | Verizon prepaid pricing with no credit check, activated on the web or through the automated assistant |
| Walmart Family Mobile | Verizon | Yes, on a published device list: iPhone SE (3rd gen) and 13 through 17, Galaxy A16/A26/A35/A36/S25 FE, recent Moto | One-stop purchase in a Walmart store, with family-line pricing |
| TextNow | T-Mobile | Yes, eSIM on the ad-supported tier | A free US number for calls and texts, with data bought on top |
Two cautions. First, budget brands cap data speeds during congestion — Visible and Cricket deprioritize behind the parent network’s direct customers, and Metro slows after roughly 35 GB in a cycle. The second caution is that prepaid brands here run on one network apiece. You get Verizon’s towers on Visible and nobody else’s, which matters the moment you leave the city or cross into a dead zone. US Mobile and Google Fi are the exception: US Mobile lets you choose Verizon or T-Mobile when you sign up, and Google Fi moves between T-Mobile and US Cellular on its own.
A third caution applies to two well-known brands in that table. Xfinity Mobile and Spectrum Mobile are not open to the public in the way the others are — both require a residential internet account from the same company (Xfinity Internet for the first, Spectrum Internet for the second) before a mobile line can be added. If you are staying in a hotel or an Airbnb with no cable account in your name, those two are out of reach, however good the price looks. Tracfone and Walmart Family Mobile sit at the opposite extreme: no broadband precondition, but a short eSIM device list that stops at recent iPhones plus a handful of Galaxy A and Moto models.
MetroPCS, Sprint and the other legacy names visitors still search
Three older names keep surfacing in search, and each has a different answer in 2026. MetroPCS is the pre-2018 name of Metro by T-Mobile: the brand was folded into T-Mobile and renamed, eSIM support carried over, and the activation rule did not — you still have to be physically in the United States for a Metro eSIM to activate. Sprint no longer exists as a carrier: the merger with T-Mobile closed in April 2020, the brand was retired, and Sprint SIM or eSIM stock is no longer sold, so any “Sprint eSIM” plan you find on a resale site is a legacy artefact rather than a live product. The practical replacement is a T-Mobile line or any T-Mobile MVNO in the table above.
The third name is not a brand at all. “AT&T eSIM card” is a phrase people search, but AT&T does not sell an eSIM card as a separate item — the eSIM is a chip soldered into your phone, and what AT&T issues is an activation: a QR code or an in-app push from att.com/eSIM once you have bought a prepaid plan. If a site offers to ship you an “AT&T eSIM card”, that is a physical SIM kit or a reseller, not an eSIM. The same logic applies in reverse: an eSIM card for AT&T coverage that you can buy before you fly is a travel eSIM profile riding AT&T’s network, not an AT&T product.
One spelling note while you are here, because it changes which brand you land on: H2O Wireless gets typed as h20 and as h2o wireless with equal frequency, and all three spellings point at the same AT&T reseller in the table above. English “h two o” and the number twenty look identical in most fonts, which is why the typo outnumbers the correct spelling in search data.
Direct from a carrier or a travel eSIM: which is better?
| Direct from a US carrier or its prepaid brand | Travel eSIM on a US network | |
|---|---|---|
| What you need | A compatible, unlocked phone; a payment method the checkout accepts | A compatible, unlocked phone |
| How the profile arrives | In-app activation or a QR code, usually after you land | QR code or app install immediately after checkout, before you fly |
| Typical cost | From $25 to $55 per month depending on the brand and data | A single upfront price, no SIM fee |
| Network access | One carrier (or its prepaid brand) | Automatic switching between T-Mobile, Verizon and AT&T |
| Best for | Stays of a month or more, or anyone who needs a US phone number | Trips of one to three weeks, and anyone who wants to be online on landing |
For a normal vacation the cost difference is lopsided. A US prepaid plan charges monthly whether you use it or not and locks you to one network; a Roami travel eSIM buys data at wholesale and lets the device move between networks. Where the carrier wins is longevity and voice — a real US number, unlimited domestic calling, and a plan that still works in month six.
💡 A multi-network US eSIM profile is the practical middle path: it keeps the convenience of instant delivery, switches automatically between T-Mobile, Verizon and AT&T, and still lands you on T-Mobile in the city and Verizon in the parks without buying twice.
Phone requirements for a United States eSIM
Three things decide whether your phone works on a US carrier: its bands, its lock status, and a short list of device-specific quirks. All three are covered below.
Which 5G bands do US carriers use?
US carriers build their 5G on different bands, and the differences decide whether you see fast 5G or fall back to LTE. T-Mobile leans on n71 (600 MHz) for rural reach and n41 (2.5 GHz) for mid-band speed. Verizon uses n77 (C-band) for mid-band and n260/n261 (mmWave) in dense downtowns and stadiums. AT&T uses n5 (850 MHz) low-band and n77 mid-band. Plenty of international handsets ship without n77, which is the band AT&T and Verizon depend on for mid-band speed.
You can skip the band tables entirely. The dependable check is to compare the exact model number against the eSIM device checker. For the mechanics ahead of the purchase, see what happens when a phone loads an eSIM profile.
Will United States carriers work with your phone?
A locked phone is the most common reason a US eSIM install simply fails, and the rules here are cleaner than many visitors expect.
Under the CTIA Consumer Code, US carriers must unlock devices, but the timing differs by plan type. Postpaid phones unlock once the device financing is paid off and the account is in good standing. Prepaid phones unlock no later than one year after activation. Carriers unlock “upon request” rather than automatically in most cases. The one exception travelers used to rely on — Verizon’s 60-day automatic unlock — was waived by the FCC in January 2026, so a Verizon phone activated after that ruling may stay locked to Verizon’s network for up to a year like other prepaid devices. That rollback matters if you buy a phone in the US and expect to roam its eSIM elsewhere quickly.
Where: iPhone, Settings -> General -> About -> Carrier Lock. When the field reads “No SIM restrictions”, the device is free and clear. A “SIM locked” reading stops any third-party profile from installing until the lock is cleared.
Fix it: call the carrier that sold you the phone and ask for the unlock code. Paid-off postpaid devices are normally cleared within a couple of business days, and there is no fee. Only then try installing your eSIM.
If you bought a used phone, or a phone from a US carrier on a payment plan, assume it may be locked and check before you fly. The FCC publishes a plain-language guide to unlocking your mobile phone that explains the commitments carriers made under the CTIA code.
Device problems that stop a US eSIM from working
| Device | Symptom | What to do |
|---|---|---|
| Mainland-China iPhone models | No “Add eSIM” option at all — the hardware is disabled in that market | Not fixable; use a physical SIM or another device |
| Carrier-purchased locked phones | eSIM greyed out in settings | Ask the carrier to unlock it first, then reboot |
| International handsets without n77 | Fast on T-Mobile, LTE-only on AT&T and Verizon mid-band | Expected behavior — see the region notes below |
| Dual-SIM users | eSIM installed but no data | Set the eSIM as the line used for mobile data |
Anything left over is a handset problem, not a US carrier problem. Verify the handset against the handset compatibility checker before you pay for data.
How much do US eSIM plans cost?
Four routes exist, and they differ more in paperwork than in price: T-Mobile’s tourist eSIM, AT&T prepaid or Cricket, Verizon prepaid or Visible, and the T-Mobile budget brands Metro and Mint. Each route, step by step:
How to buy the T-Mobile eSIM USA tourist plan
T-Mobile is the only national carrier with a prepaid eSIM product built specifically for short-term visitors, which makes it the closest thing to a T-Mobile USA eSIM you can arrange before you fly.
T-Mobile tourist eSIM, step by step:
- Download the T-Mobile Prepaid eSIM app and choose a plan. The US Pass tourist tiers give 30 days of unlimited talk, text and data starting at $50, plus taxes and fees.
- Activate inside the app. T-Mobile states no ID required and no paperwork — you pay with a domestic or international card from select countries.
- You must be in the United States for the plan to activate, and you need Wi-Fi to install the profile. Plans start the moment you buy them, so purchase on the day you intend to use service.
- Once active, you get hotspot data, Wi-Fi calling, scam-blocking and unlimited talk, text and data across the US, Canada and Mexico on T-Mobile’s network.
T-Mobile markets this directly at international travelers, and the app checks eSIM compatibility before you pay. Regular T-Mobile prepaid lines also support eSIM, but the tourist route is the one designed for someone who has not landed yet and has no US billing address.
How to buy AT&T or Cricket as a visitor
AT&T sells its own prepaid eSIM, and it also owns Cricket Wireless, which is the lower-friction visitor path.
For an AT&T prepaid eSIM, you sign up through AT&T’s prepaid pages or the myAT&T app, pick a plan, and install the profile by QR code or in-app activation. A credit check is not required for prepaid, but AT&T’s checkout can reject some international cards, so budget for a payment-method hiccup.
Cricket is simpler for most visitors:
- Cricket runs on AT&T’s network and offers eSIM activation with no credit check.
- Entry pricing is $30 per month for 5 GB, with unlimited tiers at $55 and above.
- A physical SIM carries a one-time fee in a Cricket store, but the eSIM route is digital.
- Cricket covers the US, Canada and Mexico on select plans, which is useful if your trip crosses a border.
If you only want AT&T coverage as a visitor and do not need an AT&T-branded account, Cricket gets you the same towers with less paperwork.
How to buy Verizon or Visible as a visitor
Verizon sells a prepaid eSIM through verizon.com and the My Verizon app, delivered by QR code email for compatible devices. Postpaid Verizon plans want a US credit check and a US address, so visitors normally land on prepaid or on Verizon’s budget brand Visible. Activating an eSIM on Verizon is the part that trips people up: the profile arrives as a QR code, and the line stays inactive until you scan it from the phone that will use it, so do not forward the email to a laptop and expect to finish later.
Visible is the easy Verizon route:
- Visible is an online-only Verizon brand — there are no stores, so everything happens in the app.
- Plans start at $25 per month for unlimited data, hotspot at 5 Mbps, and SD video, or $45 per month (Visible+) for Ultra Wideband 5G and 10 Mbps hotspot.
- eSIM activation is supported, and there is no contract.
- The trade-off is support: with no store, you rely on chat, text or social channels.
Visible gives you Verizon’s network and the widest geographic coverage in the country, at a price a tourist can buy for one month and walk away from.
Cheapest United States eSIM data plans
| Plan | Network | Data | Price | eSIM |
|---|---|---|---|---|
| T-Mobile US Pass | T-Mobile | Unlimited (30 days) | From $50 | Yes, tourist app, no ID |
| Cricket 5 GB | AT&T | 5 GB per month | $30 per month | Yes, no credit check |
| Visible | Verizon | Unlimited | $25 per month | Yes, online only |
| Metro by T-Mobile (BYOD) | T-Mobile | Unlimited | $25 per month | Yes, in-US activation |
| Mint Mobile (intro) | T-Mobile | 5 GB to unlimited | From $15 per month intro | Yes, app activation |
Prices are before taxes and fees unless a brand states otherwise, and they change often. For the live line-up, our United States eSIM plans page reflects today’s options. If you would rather test a network than commit to it, a free eSIM USA trial is the cheapest way to find out whether T-Mobile holds signal in the exact places you plan to sleep and drive.
What to have ready before buying a US eSIM
| Item | Why it matters |
|---|---|
| IMEI | Dial *#06# to confirm the device is eSIM-capable |
| EID | Also from *#06#; this is the eSIM’s own identifier |
| Photo ID | Passport is standard if you use a carrier store or postpaid route |
| A payment method the checkout accepts | Some US carrier checkouts reject foreign billing addresses |
| Wi-Fi | Install the profile before you travel or on arrival, not mid-transit |
| A US contact or address (optional) | Needed only on some postpaid or carrier-store routes |
United States eSIM coverage: T-Mobile vs Verizon
Two questions drive this section: how fast each network is in the places you will visit, and what your trip looks like. The awards and medians below answer the speed half; the trip table answers the other half.
T-Mobile vs Verizon: which United States carrier is faster?
All figures below come from Ookla’s Speedtest Intelligence data for 2H 2025 (collection period July–December 2025) for the United States, published in the Speedtest Connectivity Report. They are national-level measurements, not single-city speed tests.
| Metric | T-Mobile | Verizon | AT&T |
|---|---|---|---|
| Speedtest Connectivity Score | 81.52 (highest) | 76.57 | 74.5 |
| Speed Score | 73.26 (fastest) | 64.54 | 62.51 |
| Consistency Score | 87.9 (best) | 85.1 | 81.2 |
| Coverage Score | 23.9 | 30.0 (best) | 25.2 |
| 5G Availability | 91.2% | 59.9% | 87.5% |
| Video Streaming Score | 84.15 (best) | 82.81 | 80.21 |
| Game Score | 87.01 (best) | 84.75 | 83.88 |
| 5 Star Rating | 3.73 (highest) | 3.29 | 2.98 |
Empty cells here mean Ookla published nothing for that carrier rather than an estimate being filled in. Two things worth noticing: T-Mobile leads on speed and 5G availability (91.2% of samples on 5G), while Verizon’s win is geographic coverage — its 30.0% Coverage Score is the share of the country’s area it reaches, even though its 5G availability (59.9%) trails because mmWave and C-band are concentrated in cities. AT&T sits between them and recorded the strongest fixed broadband of the three.
The best US carrier for your itinerary
| Trip type | Recommended carrier | The reason | Watch out for |
|---|---|---|---|
| City break — New York, Los Angeles, Chicago, San Francisco | T-Mobile | Fastest Speed Score and near-universal 5G availability downtown | Verizon’s mmWave is faster in a few stadium and venue hotspots |
| Road trip and national parks | Verizon | Best geographic coverage; holds signal where the others fade | Even Verizon has real gaps inside the largest parks |
| Video, streaming, gaming | T-Mobile | Best video score (84.15) and game score (87.01) | Upload speeds trail on congested towers |
| Business travel and video calls | T-Mobile or Verizon | T-Mobile on speed, Verizon on reach | Hotel lower floors can kill signal — ask for a higher room |
| Budget traveler | Visible (Verizon) or Cricket (AT&T) | $25 or $30 per month, no contract | Deprioritized behind the parent network in busy areas |
| Cross-border itinerary | A North America plan | A US-only eSIM dies at the Canada or Mexico border with no warning | Day trips to Niagara or Tijuana catch people out constantly |
| Cruise port stay | Verizon or T-Mobile | Strong port-city coverage for embarkation days | Once the ship is offshore, only satellite messengers work |
T-Mobile vs Verizon: coverage compared
Distance is the whole story here: the networks are near-identical in Manhattan and wildly different across Nebraska or inside Yellowstone. Here is what each stretch of the country actually delivers.
| Region | Reality on the ground |
|---|---|
| Northeast corridor | Excellent in New York, Boston and Washington; strong along the Amtrak Northeast Corridor and major interstates. |
| California and the West Coast | Dense urban 5G in LA, San Francisco and San Diego; rural interior stretches thin out fast. |
| Midwest | Cities are well covered on all three networks; rural farmland between towns has large gaps, and Verizon generally holds the longest stretches. |
| National parks (Utah, Arizona, Wyoming, Montana) | Towns like Moab and West Yellowstone have service; inside the parks themselves coverage is sparse to nonexistent. Download offline maps before you drive in. |
| Alaska and the remote northwest | Anchorage, Fairbanks and Juneau are covered; the highway between them and most of the bush is not continuous. A satellite messenger is the right tool there, not a better eSIM. |
Planning a route that leaves the United States? Start with eSIM for Canada, compare Mexico eSIM plans, or if your itinerary crosses borders more than once, a North America eSIM saves you buying twice.
Here, automatic network selection is the whole advantage. A United States eSIM that can move between T-Mobile, Verizon and AT&T covers the regional gaps that any single-carrier plan cannot.
US eSIM APN settings: what to enter and when
Only a handful of values matter here, and you will need them only if automatic configuration fails. Below: the values for the three national carriers, when manual entry is genuinely required, and the exact menu paths.
APN values for T-Mobile, Verizon and AT&T eSIMs
You will only need these if you bought a SIM or eSIM directly from a US carrier or its prepaid brand. Travel eSIM profiles bring their own US APN and should be left as they are.
| Carrier | APN | Username | Password |
|---|---|---|---|
| T-Mobile | fast.t-mobile.com |
blank | blank |
| AT&T | phone |
blank | blank |
| Verizon | vzwinternet |
blank | blank |
Budget brands inherit their parent’s network values: Visible uses Verizon’s vzwinternet, Cricket uses ndo, Metro by T-Mobile uses fast.metropcs.com, and Mint Mobile uses wholesale. Leave username and password empty unless the activation instructions that came with your profile state otherwise.
When does a US eSIM need manual APN entry?
T-Mobile and the MVNOs usually provision the APN for you, so a manual entry is a fallback rather than a step in the setup. It is worth doing when:
- A device too dated to pick up carrier settings automatically
- A profile installed with a manual activation code instead of a QR scan
- A carrier-issued prepaid eSIM where automatic configuration did not run
- Almost never on a travel eSIM — that is the point of a managed profile
Where to enter APN settings on your phone
- iPhone: Settings → Cellular → tap the eSIM line → Cellular Data Network → enter the APN
- Android: Settings → Connections → Mobile Networks → Access Point Names → add a new APN
After saving, restart the phone. If data is still dead, confirm the active data line is the US eSIM rather than your home SIM.
How to install and activate a United States eSIM
One trip through this section: clean install to working data, with the failure patterns a US network can produce covered in the order they arrive.
How to install a United States eSIM on your phone
| # | Check | What “good” looks like |
|---|---|---|
| 1 | Phone is not carrier-locked | About screen lists Carrier Lock: “No SIM restrictions” |
| 2 | Phone supports eSIM | *#06# shows an EID, or the compatibility page confirms your model |
| 3 | QR code and activation code saved | Screenshot stored on the phone and in cloud storage |
| 4 | Profile installed before departure or on arrival Wi-Fi | Install on Wi-Fi; the profile connects when you land |
| 5 | Data line and roaming set | eSIM selected for mobile data, data roaming on |
Do step 4 on solid Wi-Fi. US airport arrival halls have congested Wi-Fi exactly when you need it most, and a profile you install on the ground competes with everyone else’s.
How to activate a United States eSIM
The standard install sequence from Add eSIM to the roaming switch is covered in our activation walkthrough. What differs by carrier:
- T-Mobile (tourist eSIM): activated in the T-Mobile Prepaid eSIM app; no QR scan needed, and activation must happen while you are in the US.
- AT&T: prepaid eSIM installs via QR code or the myAT&T app; some international cards are rejected at checkout.
- Verizon: the profile is issued by the carrier and emailed as a QR code for compatible devices; prepaid avoids the postpaid credit check.
- Visible / Cricket / Metro / Mint: brand-specific app or QR activation on the parent network; Visible and Cricket are the lowest-friction visitor routes.
- Travel eSIMs: install by QR code, and the same profile roams onto whichever of T-Mobile, Verizon or AT&T is strongest.
Three fixes when your United States eSIM does not work
General activation errors — a profile that will not download, a scan that fails, an eSIM that installs but never registers — are covered in our eSIM troubleshooting resource. The patterns below are the US-specific ones.
A. The eSIM will not install
- Make sure no lock is present: About -> Carrier Lock shows “No SIM restrictions”
- Look at the QR: legible, and never scanned before
- For T-Mobile’s tourist eSIM, confirm you are physically in the US, since activation is location-checked
B. Installed, but no signal bars
- Re-check the lock status
- Settings → Cellular → Network Selection → select T-Mobile, Verizon or AT&T manually instead of automatic
- Full network settings reset, then another reboot
C. Signal bars, but no internet
- Put the APN back in precisely as the table lists it (common on AT&T and Verizon prepaid)
- Verify the US eSIM is the active data line and not your home SIM.
- Check you have not exhausted your data allowance — budget brands deprioritize rather than cutting off
What to gather before contacting US eSIM support
| Information | Where to find it |
|---|---|
| Order or account number | Confirmation email |
| Phone model and OS version | Settings → About |
| EID | *#06# |
| Screenshot of the error | Take it before the screen changes |
| Current APN settings | Settings → Cellular Data Network |
| Data roaming status | Settings → Cellular → your eSIM line |
| Steps already tried | Keep a short list |
United States eSIM carrier questions from real travellers
Can international visitors buy a T-Mobile eSIM?
Yes, and T-Mobile is the easiest national route. Its Prepaid tourist eSIM and US Pass plans are built for short-term visitors: no ID, no US address, activation in the T-Mobile Prepaid eSIM app, with 30 days of unlimited talk, text and data from $50. The one rule is that activation happens while you are in the United States, so install it on arrival Wi-Fi rather than at home.
Does a Verizon eSIM require a US address or SSN?
For a Verizon prepaid eSIM, no SSN is required, and sign-up is online. A full postpaid Verizon plan is a different story — that route wants a US credit check and a US billing address. Most visitors are better served by Verizon prepaid eSIM or by Visible, Verizon’s online-only brand, which sells unlimited data from $25 per month with eSIM activation and no store visit.
Can I get an AT&T prepaid eSIM without a US credit check?
Yes. AT&T prepaid eSIM needs no credit check, though AT&T’s own checkout can reject some foreign cards. The smoother visitor path is usually Cricket Wireless, which AT&T owns: Cricket runs on AT&T’s network, supports eSIM with no credit check, and starts at $30 per month for 5 GB. You get AT&T coverage without an AT&T account.
Rural coverage in United States: T-Mobile vs Verizon
Verizon, on the evidence. It recorded the Best Mobile Coverage in the United States with a Coverage Score of 30.0% on Ookla’s 2H 2025 report — the share of the country’s geography it reaches, which is the closest thing to a rural-reliability measure. T-Mobile is faster where it has signal, and AT&T sits between them, but for long drives through the Midwest and interstates, Verizon holds the longest stretches.
What are the cheapest US eSIM options?
Visible, at $25 per month for unlimited data on Verizon’s network, or Mint Mobile at a $15 per month intro rate on T-Mobile’s network if you pay for several months upfront. Cricket starts at $30 per month for 5 GB on AT&T. All three are prepaid with no contract, so you can stop after one month. Watch for deprioritization during congestion rather than a hard data cut-off.
Which phones have problems with US travel eSIMs?
It needs to be unlocked and eSIM-capable, and it helps if it supports the right bands — T-Mobile’s n71 and n41, or AT&T and Verizon’s n77 mid-band. Check both in one pass with the eSIM compatibility page, which covers EID support and the band question. If you want the install sequence explained first, read the eSIM activation explainer.
How do I get my locked phone unlocked in the United States?
Ask the carrier it is locked to. Under the CTIA Consumer Code, postpaid phones unlock once device financing is paid and the account is in good standing; prepaid phones unlock within a year of activation; carriers unlock on request. Verizon’s old 60-day automatic unlock was waived by the FCC in January 2026, so newer Verizon phones may stay locked longer. Paid-off devices are usually cleared within a couple of business days. Look for the lock line at Settings → General → About → Carrier Lock.
Should I buy from a US carrier or use a travel eSIM?
Direct means one network, carrier-issued provisioning, and often a US number and unlimited domestic calling in exchange for more paperwork. A travel eSIM means instant delivery, no paperwork, automatic switching between T-Mobile, Verizon and AT&T, and a fixed upfront price. Short trip: travel eSIM. Months in the US, or you need a local number: direct.
Do United States carriers offer tourist specific eSIM plans?
T-Mobile does — it markets a tourist eSIM and US Pass plans for international visitors, with no ID, from $50 for 30 days of unlimited service. AT&T and Verizon route visitors to prepaid tiers and their brands Cricket and Visible rather than a labeled “tourist” product, but those prepaid eSIMs work the same way for a short stay.
Can I keep two eSIMs active at once?
Yes, and it is a sensible setup. Keep the home SIM for calls and text verification, and let the US eSIM carry the data. Set the US profile as the data line in Settings and leave voice on your home SIM. Watch two things: switch roaming off on the home line to avoid surprise charges, and remember that most data-only profiles cannot receive texts, so verification codes go to your home number.
How does eSIM activation work on US carriers?
Nothing gets swapped or mailed: the eSIM is soldered into the handset and a US carrier simply pushes your profile onto it over the air. From then on the line behaves like any ordinary SIM, complete with the carrier’s APN and roaming rules. The delivery chain and the one-scan QR limit are set out in eSIM activation explained.
US eSIM activation not working? Try these fixes
Work the three US-specific patterns above in order — lock status, network selection, then APN and data line — and if it still fails, the wider error catalogue in eSIM activation fixes guide covers the rest. Line up your EID, order number and an error screenshot before you reach support.
