How to Activate an eSIM on iPhone or Android — 3 Steps, 2 Minutes

Editor’s Note: Activating an eSIM takes about five minutes — you scan a QR code or enter an SM-DP+ address and let the profile download. The steps below are the exact ones our support team uses, tested on iOS 17/18 and Android 13/14/15. Follow the path for your phone and you’ll be online before takeoff.

The Bottom Line Up Front: Activating an eSIM means downloading a digital carrier profile onto your phone. Whatever brand you own, the recipe is the same: an unlocked phone, a stable Wi-Fi connection, and a QR code (or its manual-entry details) from your provider.

1. Open the add-eSIM screen. iPhone: Settings > Cellular > Add eSIM. Android: Settings > Connections (or Network & internet) > SIM Manager > Add eSIM — the exact path for each brand is in the table below.
2. Scan the QR code, or type the SM-DP+ address and activation code. The profile download takes 30–60 seconds; stay on Wi-Fi until it finishes.
3. Turn Data Roaming ON for the new line. Full signal bars with no internet is almost always this one setting.

If the install is already failing, skip to the fix ladder or the greyed-out Add eSIM table. If you want to know what’s happening on the carrier side while that spinner turns, read activation vs download. New to the technology itself? What is eSIM? covers the hardware underneath.

On an iPhone? Everything is on this page: the iOS walkthrough, converting a physical SIM to eSIM, iMessage and FaceTime re-registration, and the iOS 17 vs iOS 18 label changes. Using an iPhone 16 and seeing “Unable to Activate”? The iPhone 16 eSIM guide covers the model-specific cases.

Does your phone even support eSIM?

A 10-second check: dial *#06# and look for a 32-digit EID. If it’s there, you’re ready. For the full device-by-device list — every Android brand and older iPhone — see the complete eSIM compatibility list.

eSIM Activation Pre-Flight Checklist

Most activation failures are preventable before you scan anything. Run these six checks first.

Skip any of these and you’ll likely land in the troubleshooting queue. The three most common causes of failure, in order: a carrier-locked phone, weak Wi-Fi mid-download, and scanning with the Camera app instead of through Settings.

Prep actions worth doing before you scan

The table above is about checks. This list is about actions — things worth doing before you tap “Add eSIM” so you never have to scramble mid-setup.

1. Save the QR code to Photos. Screenshot it or download the image, so you can use “Choose Photo” instead of aiming your camera at another screen. If the code is in an email, this also means you aren’t re-opening your inbox on the spot.
2. Screenshot the SM-DP+ address and activation code. These two strings are your offline fallback. With them saved, a broken QR code can’t stop you.
3. Download the provider’s app and log in. Roami, Airalo, and Holafly all offer one-tap install from inside their app — but only if you’re already signed in before you leave decent Wi-Fi.
4. Charge the phone above 50%. A profile download is tiny, but a phone that dies mid-install can leave a half-written profile you then have to remove and re-add.
5. Know your lock-screen passcode. iOS and Android both prompt for it to authorize the install. If you’ve been using Face ID or a fingerprint forever, type the passcode once first to be sure you remember it.
6. Confirm the phone is unlocked. On iPhone: Settings > General > About > Carrier Lock. On Android: ask your carrier, or test a friend’s SIM from another network.
7. Install on home Wi-Fi, not airport Wi-Fi. You can install weeks before your trip; the plan stays inactive until your phone connects to a network in the destination.
8. Decide which line does what. If you’re keeping your home SIM, plan now: travel eSIM handles data, home SIM handles calls and texts. We cover this below.

How to Activate eSIM on iPhone

Every Apple iPhone since the XS follows the same path, whether you are buying your first eSIM for iPhone from a travel provider or reinstalling a plan you have used before — and there is no eSIM card for iPhone to insert, because the profile lives on the phone’s own chip. Go to Settings > Cellular, tap Add eSIM (or Add Data Plan), choose Use QR Code, and hold the phone steady about 15 cm from the code. When “Cellular Setup Complete” appears, you’re done — the download usually takes 30–60 seconds.

No camera? Tap Enter Details Manually and paste the SM-DP+ address and activation code from your provider’s email.

If activating eSIM on iPhone stalls at “Activating…” instead of finishing, jump to the stuck-activation ladder rather than deleting the profile and scanning again. Once the profile lands, the eSIM in iPhone 14 — and in every model after it — is a profile on the chip rather than a card in a tray, so the line belongs to the handset and not to a piece of plastic you can lose.

Convert a physical SIM to eSIM on iPhone

If your carrier supports it, iOS can turn the plastic card into a profile on the phone itself — no store visit, no QR code. It’s the cleanest way to free the physical slot for a local SIM abroad, or to go all-digital before selling the phone.

1. Settings > Cellular.
2. Tap the line that’s currently on your physical SIM.
3. Tap Convert to eSIM (some carriers label it Convert Physical SIM to eSIM).
4. Confirm with Convert Cellular Plan, then Convert to eSIM.
5. Wait under a minute, then remove the card when iOS prompts.

Three catches. Carrier support varies — AT&T, Verizon and T-Mobile offer it, many MVNOs and prepaid brands don’t show the option at all. The phone must currently be on that carrier’s network, because iOS verifies the line during conversion. And a travel or foreign SIM can’t be converted — only the line your iPhone is signed in with. Once converted, the plastic card is dead; cut it up rather than passing it on.

No “Convert to eSIM” in the menu? Your carrier hasn’t enabled it. Ask them for an eSIM QR code instead and use the install path above.

That conversion only runs in one direction. Turning a SIM card to an eSIM takes four taps on the phone, but there is no menu for going from an eSIM to physical SIM — that is a carrier-side re-issue, where support re-points the line onto a plastic card and the downloaded profile dies the moment the new card activates. Worth knowing before you convert a work line you might need to hand over.

The same swap exists at every carrier, and Vodafone is the one people search for most. A Vodafone SIM to eSIM conversion is a carrier-side operation — done in the My Vodafone app, on the account page, or at a store if the app refuses — and it moves your existing number onto an eSIM profile without a new plan or a new contract. Expect a few minutes without service while the old SIM is cancelled, so start it on Wi-Fi rather than at an airport gate. The travel use is less obvious but useful: convert at home, and the physical SIM slot is then free for a local SIM abroad, which is the mirror image of the usual setup and works just as well.

Re-register iMessage and FaceTime

Most guides stop at “Cellular Setup Complete,” then people spend an evening wondering why texts arrive on the wrong number. If you changed your default voice line, iMessage and FaceTime can stay tied to the old one — or sit on “Waiting for activation.”

1. Settings > Messages > Send & Receive — confirm your number is ticked.
2. Settings > FaceTime — confirm the right number or Apple ID is active.
3. Stuck on “Waiting for activation”? Toggle iMessage off and back on while on Wi-Fi.

This matters most on dual-line setups, where the travel eSIM is data-only and you want messaging to stay on your home number.

“Add eSIM” greyed out or “Add Cellular Plan” missing

If the option is dimmed or absent, something upstream is blocking it. Work down this table — the first two rows account for most cases.

iOS 17 vs iOS 18: what changed in the menus

The labels drift between releases, which is why a two-year-old tutorial can send you looking for a button that no longer exists.

“Add Cellular Plan” and “Add eSIM” are the same function. If a guide mentions one and your phone shows the other, nothing is wrong.

Moving an eSIM to a new iPhone

Setting up a new iPhone near the old one? Choose Transfer eSIM from Nearby iPhone and keep both devices close with Bluetooth and Wi-Fi on — the profile moves in a minute or two. If the prompt doesn’t appear, go to Settings > Cellular > Add eSIM > Transfer from Nearby iPhone on the new phone.

That only works when the old phone is present, powered on and unlocked. If it was sold, lost or erased, the carrier has to re-issue the profile — the full set of paths, including Android-to-iPhone, is in the eSIM transfer guide.

How to Activate eSIM on Android

The menu label changes by brand, but every Android eSIM path is “open settings, find Add eSIM, scan or type.”

If the option is missing, your model likely lacks eSIM hardware — confirm with the device compatibility list.

Manual entry on Android

When the QR won’t scan, look for “Enter activation code manually” or “Need help?” in the Add eSIM screen, then type the SM-DP+ address and activation code. This works on every Android eSIM phone and is the most reliable fallback.

Android menu paths, brand by brand

The table above gets you there; this is the detail underneath it. Each brand names the same feature slightly differently, and the path moves a little between software versions.

If you don’t see any of these, search “eSIM” in the Settings search bar. If nothing surfaces, the phone almost certainly lacks eSIM hardware — full model-level detail is in the Android eSIM brands guide and the full device list.

Where to find the SM-DP+ address and activation code

Manual entry needs two strings that live in your confirmation email or provider app.

Screenshot these before you fly — with no Wi-Fi on landing, you can’t look them up.

How each major provider delivers your eSIM

“Activate” means slightly different things depending on who sold you the plan. Here’s what to expect from the five most common travel-eSIM providers, so you know exactly what’s in your inbox and how you’ll install it.

The pattern: all five deliver the QR or the profile almost immediately, and the fastest install is always the provider’s own app. Where they differ is where the QR lives (email vs app) and when the plan’s clock starts (at install vs at first connection). If you’re on the fence, Roami’s email includes both the QR and the manual-entry strings, which is the most forgiving setup for a first-timer.

Activate via a carrier app

Providers like Roami, Airalo, and Holafly let you skip the QR entirely. Download the app, open your purchased plan, tap Install or Activate, and allow the phone to add the cellular plan. It’s identical on iPhone and Android, and it’s the cleanest route for first-timers because the app can’t scan its own screen.

Which eSIM Activation Method Should You Use?

You have three ways in, and they aren’t interchangeable in every situation. Pick by context.

Our advice: use the provider’s one-tap app route for your first eSIM, and keep a screenshot of both the QR and the manual-entry strings as a backup. The app is fastest, but the manual strings are the one thing that can’t let you down if everything else goes sideways.

Keep your home number while using a travel eSIM

This is the setup most travelers actually want: the home line stays exactly where it is, and a travel eSIM rides along for data. The order of these seven steps matters — do them before you leave.

1. Leave the home line alone. Physical SIM or eSIM, don’t delete it, don’t convert it.
2. Install the travel eSIM by QR, manual entry, or the provider’s app.
3. Label both lines. Settings > Cellular > tap a line > Cellular Plan Label — “Home” and “Travel” beat “Primary” and “Secondary.”
4. Point Cellular Data at the travel eSIM.
5. Point Default Voice Line at your home number. Calls, iMessage and FaceTime stay on the number people already know.
6. Data Roaming ON for the travel line, OFF for home. The travel eSIM needs roaming to reach partner networks; leaving it on for your home line invites daily charges.
7. Leave “Allow Cellular Data Switching” OFF. With it on, a brief signal dip can flip data to your home line mid-day and trigger a roaming fee.

Do that and you get data from the travel eSIM with a number everyone can still reach — no SIM swapping, no second phone. If the second line shows bars but pages won’t load, it’s an APN issue rather than an activation one; the APN values are in the deep troubleshooting guide.

Managing eSIMs after activation

Once two or three profiles are installed, a little housekeeping stops them becoming a confusing pile.

• Label every line. Settings > Cellular > a line > Cellular Plan Label. “Home,” “Roami Travel,” “Spain” — anything better than the defaults.
• Turn lines off instead of deleting. Settings > Cellular > a line > Turn On This Line. A dormant travel eSIM stops registering and stops drawing battery, but stays stored for the next trip.
• Mind the active-line limit. iPhone 13 and later run two active lines at once; a third profile can be stored but not enabled until you turn one off.
• Delete only after the plan expires. QR codes and activation codes are usually single-use, so deleting a live plan can mean buying a new one.

eSIMs and iCloud backups

The thing most people learn the hard way: eSIM profiles are not part of your iCloud backup. A restore brings back apps, settings and photos — not cellular profiles. They live on the phone’s eUICC chip, and only three things move them: Quick Transfer, a carrier re-issue, or re-downloading from your provider.

• “Erase All Content and Settings” removes your eSIMs. Erase before selling or trading in, and you’ll be re-installing every line afterwards.
• Restoring to the same phone leaves them alone; restoring to a new phone still needs Quick Transfer or a carrier re-issue.
• A backup won’t rescue a lost profile. If the phone is gone, only the carrier can issue a replacement — which is another reason to keep the manual-entry strings somewhere off the phone.

How to confirm activation succeeded

Don’t trust the “Cellular Setup Complete” message alone. Verify three things:

1. Status bar — you see signal bars (and a second set if both lines are on).
2. Settings — the eSIM line reads “On” or “Active,” not “No Service.”
3. Real test — turn off Wi-Fi, set the eSIM as your data line, and load a webpage.

Give it up to two minutes to register on the local network. If it still says “Searching,” see the troubleshooting pointer below.

How long does activation actually take?

Short version: the download takes under two minutes, but the first connection can take up to 15 minutes after you land. They’re two different things, and people confuse them.

Why are some carriers slower to register than others? Three reasons. Smaller carriers provision in batches — your profile is technically “pending” until their system processes it on the backend. The partner network is congested — landing at a busy airport at 6 p.m. means your phone is one of thousands registering at once. And some plans only start their clock at first connection, so the network handshake is deliberately delayed until the first data session. None of this is a fault — it’s just the difference between “installed” and “live.”

Activation vs download

“Activated” gets used for three different events, and mixing them up is why a working eSIM can feel broken:

• Download (install) — the profile lands on the phone’s eUICC chip. This is the part that needs Wi-Fi, and the part your provider’s QR code triggers.
• Activation (carrier side) — the provider ties that profile to a plan, a data allowance and a billing record. Some do it at purchase; others wait until the profile first connects to a network.
• Registration (network side) — the phone negotiates with a local partner tower. This is where “Searching…” lives, and up to 15 minutes on arrival is normal.

Only the first event happens while you’re still at home. That’s how an eSIM can sit “installed” for a week without using a single megabyte.

What is an eSIM activation code? In manual entry, the code your provider sends — sometimes called a confirmation code, or an LPA string — is the second half of the download address. The SM-DP+ address says which server to ask; the activation code says which profile to fetch. Both are usually single-use: delete the profile and the same code often won’t work again, so the provider has to re-issue it.

Common Mistakes That Break eSIM Activation

What to Do When eSIM Activation Gets Stuck

If your eSIM is stuck on activating, you are almost certainly looking at “Activating…” or “Searching” with no progress. Work this ladder top to bottom — it resolves the large majority of stuck activations without touching support.

1. Restart the phone. Sounds too simple, but a clean boot re-triggers the network handshake and clears a stuck profile half the time.
2. Toggle Airplane Mode for 30 seconds, then off. This forces the phone to re-scan local networks from scratch.
3. Re-scan the QR. Delete the pending (not yet active) profile and add it again on a stronger network. Never delete an active plan that’s already working.
4. Re-type the SM-DP+ address exactly. Manual entry is case-sensitive and space-sensitive — one stray character sends the phone to a dead server. Paste, don’t retype.
5. Turn Data Roaming ON for the travel eSIM. “No Service” with full signal bars is almost always this.
6. Move to stable Wi-Fi. If the download kept stalling, you may have a half-written profile that only re-installs cleanly on a good connection.

If the error is a specific code — “Invalid QR code,” “Cellular Plan Cannot Be Added,” an APN problem — that’s error-by-error territory, and the fixes (with APN values) live in the eSIM Deep Troubleshooting Guide.

Activate on an Android tablet or portable hotspot

eSIM isn’t just for phones. Cellular Android tablets — like the Samsung Galaxy Tab S-series or a cellular Lenovo — use the exact same path as their phone siblings: Settings > Connections (or Network & internet) > SIM Manager > Add eSIM. If your tablet has an EID from *#06#, it can take an eSIM.

Portable hotspots (MiFi) are more mixed. Most travel hotspots still take a physical SIM card, but a handful of premium units — like the Netgear Nighthawk M6 series and some ZTE and GlocalMe models — support eSIM. If you’re tethering a whole family, a hotspot eSIM can be a tidy solution, though you’ll usually get more flexibility (and cheaper plans) by putting the eSIM on one phone and sharing its hotspot instead.

Apple’s cellular iPad and Apple Watch follow their own rules — the Watch mirrors a phone line rather than taking a travel eSIM directly. That’s covered in the iPad & Apple Watch eSIM guide.

Common eSIM Activation Myths

A few things people believe about activation that just aren’t true:

• “I need to call my carrier to activate.” No — installing a profile needs no call. You only contact a carrier to re-issue a profile after you delete it or change phones.
• “I have to be in my destination to activate.” You install at home; the plan only becomes live when your phone connects to a network in the destination.
• “Deleting the eSIM resets my plan.” Deleting destroys the profile permanently — and QR codes are single-use, so you’d need a brand-new plan.
• “I can share one eSIM across two phones.” No — a profile lives on one device at a time. You can often move it between phones, but you can’t run the same profile on two at once.
• “eSIMs are slower than a physical SIM.” The credential is identical; there’s no speed difference. Your data speeds come from the network and the plan, not the SIM format.

Frequently Asked Questions

Is there a fee to activate an eSIM? No. Carriers don’t charge to scan and install a profile — you only pay for the data plan itself. Anyone charging an “activation fee” is outside normal practice.

Can I activate my eSIM before I travel? Yes, and you should. Install at home on reliable Wi-Fi; the plan stays inactive until your phone connects to a network in your destination. Just remember to switch Data Roaming on after landing.

How long does eSIM activation take? The profile download takes under two minutes. First-time connection to the local network can take up to 10–15 minutes depending on signal. Beyond that, restart the phone.

Do I need Wi-Fi to activate an eSIM? For the initial profile download, yes — the profile comes from your provider’s secure SM-DP+ server, and a weak cellular signal won’t reliably pull it. Install on home Wi-Fi before you leave, and the plan stays dormant until you land.

How many eSIMs can I keep on my phone, and can I switch between them? Most modern phones store eight or more eSIM profiles, though only one or two can be active at a time. You can switch which profile is active from the same Settings screen you used to add them — handy for a multi-country trip.

What’s the difference between QR code and manual entry? QR scanning is the standard route — faster and harder to mistype. Manual entry (SM-DP+ address + activation code) is the backup that works when the camera or the code fails.

Can I make calls and texts with a data-only eSIM? A data-only travel eSIM carries internet but no phone number, so it won’t make traditional calls or SMS. You stay reachable on your home number (via Wi-Fi Calling) while the travel eSIM handles data — that’s how most travelers run it.

My eSIM is stuck on “Activating” — how long should I wait? Up to 10–15 minutes on arrival, especially at a busy airport. If it’s still stuck after that, restart the phone, toggle Airplane Mode for 30 seconds, or delete the pending profile and re-scan on stronger Wi-Fi.

Do I need Data Roaming on for a travel eSIM? Yes — travel eSIMs reach the network through partner carriers, so Data Roaming must be ON for that line. This doesn’t incur roaming charges; it’s just how the connection works.

What does the SM-DP+ address mean? SM-DP+ (Subscription Manager – Data Preparation Plus) is the secure server that delivers your eSIM profile. In manual entry, it tells your phone where to download the profile from.

Can I use my travel eSIM with Wi-Fi Calling? Yes — Wi-Fi Calling belongs to your home line, not the travel eSIM. Keep Wi-Fi Calling on for your home number and it will work over the travel eSIM’s data (or any Wi-Fi), so you stay reachable without roaming fees.

What if I have no signal at all after activation? No bars at all usually means you’re outside the partner network’s coverage, or the phone hasn’t registered yet. Toggle Airplane Mode for 30 seconds, confirm Data Roaming is ON for the travel eSIM, and step outside if you’re indoors. Persistent “No Service” is an APN or provisioning issue — see the deep troubleshooting guide.

Can I activate an eSIM on a carrier-locked phone? No. A locked phone only accepts profiles from the carrier that locked it, so “Add eSIM” will either be missing or fail at the download step. Check Settings > General > About > Carrier Lock on iPhone (it should read “No SIM restrictions”) and ask your carrier for an unlock before you buy a travel plan.

Do I need a separate eSIM for every country I visit? Not necessarily. A regional plan — Europe, for instance — covers dozens of countries on one profile, and global plans exist too. What you can’t do is run the same single-country profile in a country it wasn’t sold for. Multi-stop trips are usually cheapest with one regional eSIM rather than three separate ones.

Can I convert my physical SIM to eSIM on iPhone? If your carrier enables it: Settings > Cellular > your line > Convert to eSIM. AT&T, Verizon and T-Mobile support it; many MVNOs don’t show the option. The phone has to be on that carrier’s network to convert. Full steps are above.
