5G Germany eSIM | Telekom, Vodafone & O2 Coverage
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 Germany eSIM means choosing between three national networks, and none of them is the automatic answer. On Ookla’s 1H 2025 Germany report, Telekom was named Best Mobile Network and Best 5G Network, with the highest Speedtest Connectivity Score at 78.87. Vodafone posted the strongest rural reach among the big three, and O2 led on 5G availability at 72.4 percent. Which one serves you best comes down to the ground you cover — the right German carrier is a routing decision, not a logo decision. Every few months this guide is rebuilt around Roami’s Germany activation logs and support tickets — press releases alone do not drive it.
Quick answer: Telekom is the safe default for coverage across Germany, with Vodafone usually cheaper in and near the main cities. Below: the numbers backing that claim, plus compatibility checker if your handset needs checking first.
If the profile will not install, no speed chart or coverage map will save the trip. The phone compatibility list and this eSIM activation walkthrough cover the fundamentals, leaving this guide free to compare networks head-on.
The short version: Staying in Berlin, Munich, Hamburg or Frankfurt? Telekom is the fastest and most consistent network in Germany. Driving through Bavaria, the Black Forest or small towns? Vodafone holds signal where O2 fades. Want a cheap city plan? O2 and its discount brands including Aldi Talk and blau undercut the others by 20 to 40 percent. The single biggest catch is identity verification: German law requires every prepaid SIM and eSIM to be registered, so there is no truly anonymous walk-up eSIM. Want to skip the paperwork and the PostIdent queue? Roami’s free trial eSIM tests the networks at no cost, and code WEB20 takes 20 percent off Germany prepaid eSIM plans.
Which German network should your eSIM use?
Telekom vs Vodafone: which is better in Germany?
| Telekom | Vodafone | O2 | |
|---|---|---|---|
| Tourist prepaid eSIM | Prepaid eSIM via customer service swap of a physical SIM, or eSIM on postpaid | Free CallYa eSIM ordered online, identity check required | Direct prepaid eSIM, passport verification online |
| Signature strength | Best overall network and best 5G network | Strongest rural and highway coverage | Cheapest and highest 5G availability |
| Lowest-cost prepaid start | MagentaMobil Prepaid from 4.95 EUR for 4 weeks | CallYa Start 1 GB for 4.99 EUR for 4 weeks | Prepaid eSIM 20 GB for 9.99 EUR for 4 weeks |
| Visitor buying process | Medium effort, verification needed | Low effort, free eSIM, verify after arrival | Low effort, verify online before travel |
The most important fact on this page is in that table: all three national carriers sell a prepaid eSIM, but every one of them requires German identity verification before the line goes live. There is no anonymous tourist eSIM sold by a German operator. Telekom makes prepaid eSIM a little harder by issuing it through customer service after a physical SIM is active, while Vodafone and O2 let you order the eSIM profile directly.
Which budget brands and regional resellers sell eSIMs
Germany’s discount brands run on the three networks and are where visitors find the lowest prices, but the eSIM path is not always instant.
| Brand | Underlying network | eSIM | Ideal user |
|---|---|---|---|
| Aldi Talk | O2 | eSIM only after you order and activate a physical SIM first | Budget city users who do not mind the extra step |
| Lidl Connect | Vodafone | eSIM via the customer portal after the plastic SIM is active | Better rural and train coverage than O2 at the same price |
| Otelo | Vodafone | eSIM via the Otelo portal after SIM activation | Vodafone network on a tight budget |
| blau | O2 | eSIM supported on prepaid and contract plans | Long stay, but contracts need EU or German residence |
| Congstar | Telekom | eSIM on prepaid and contract | Telekom coverage without Telekom premium pricing |
Two cautions. First, Aldi Talk, Lidl Connect and Otelo do not hand new customers an instant eSIM: you must receive and activate a physical SIM, then convert it in the account portal, which still triggers the same legal identity check. Second, every discount brand is capped to one host network, so Aldi Talk and blau give you O2 coverage and nothing else, which matters the moment you leave a city.
Can you buy a Germany eSIM from Telekom?
| Direct from a German carrier | Travel eSIM on a German network | |
|---|---|---|
| What you need | Passport and a verification step; some routes need a German address | A compatible, unlocked phone |
| How the profile arrives | eSIM issued by the carrier after verification | QR code or app install immediately after checkout |
| Typical 20 GB cost | Roughly 9.99 EUR for 4 weeks on Vodafone or O2 prepaid | A single upfront price, no SIM fee, no verification |
| Network access | One carrier | Automatic switching between Telekom, Vodafone and O2 |
| Best for | Stays of a month or more, or anyone who needs a German phone number | Trips of one to three weeks, and anyone who wants to be online on landing |
The economics favor a travel eSIM for a normal holiday. A German prepaid plan charges in four-week cycles and forces a passport check, while a travel eSIM buys data at wholesale and lets the device move between networks. Where the carrier wins is longevity and voice: a real German number, unlimited domestic calling, and a plan that still works in month six. If you would rather test the networks before committing to a plan, try free test eSIM and upgrade only if the coverage suits your route.
A multi-network eSIM profile is the practical middle path: a Germany eSIM plan keeps the convenience of instant delivery, switches automatically between Telekom, Vodafone and O2, and still lands you on Telekom in Munich and Vodafone in the Black Forest without buying twice.
Does my phone work with a German eSIM?
Three things decide whether your phone works on a German carrier: its bands, its lock status, and a short list of device-specific quirks. All three are covered below.
What devices are blocked from Germany eSIMs?
German carriers build 5G on specific bands, notably n78 at 3.6 GHz for capacity, n28 at 700 MHz for coverage, and n1 at 2100 MHz, while 4G LTE uses 800 MHz band 20, 1800 MHz band 3 and 2600 MHz band 7. Plenty of international handsets miss one or more of these, especially n28, and those phones still work: they fall back to LTE once you leave dense urban areas, which is fine downtown and frustrating in the countryside.
There is no need to memorise German band tables. The safest route is to compare the precise model number with the eSIM device checker. If you would rather see the internals first, what your phone does when it loads an eSIM profile walks through the process.
Will a SIM lock block your German eSIM?
A locked phone is the most common reason a German eSIM install simply fails, and Germany handles this differently from Canada. The European Union has no single mandatory unlock law like the CRTC Wireless Code, so phones are not legally required to ship unlocked. In practice, handsets bought in the EU or UK are almost always sold unlocked, which means the lock problem in Germany is almost always a phone still tied to a non-EU carrier, most often a US postpaid device still under contract.
Check it: on an iPhone, open Settings, then General, About and read the Carrier Lock line. If the entry shows “No SIM restrictions”, nothing stands in the way. Where the screen says “SIM locked”, a third-party eSIM cannot install until the lock is removed.
Fix it: reach out to the carrier that supplied the phone and ask them to unlock it. Paid-off devices are usually cleared within hours, and there is no German fee involved because the lock is held by your home carrier, not a German one. Only then try installing your eSIM.
If you picked up a second-hand phone, treat it as possibly locked and verify before your flight. Full detail sits with your home carrier, not a German regulator.
Will Germany networks accept your phone?
| 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 Samsung | eSIM greyed out in settings | Ask the carrier to unlock it first, then reboot |
| International handsets without n28 or n78 | Fast in cities, LTE only in rural areas | 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 |
| Locked non-EU phone | Install fails entirely | Unlock from the home carrier before travel |
Everything past this point is a handset issue, not a German network issue. Run your specific model through the handset compatibility checker before paying for any plan.
Germany eSIM prices compared
Four routes to a Germany eSIM exist, and they differ more in paperwork than in price: Telekom prepaid through customer service, Vodafone CallYa online, O2 prepaid direct, or a discount brand after a physical SIM. Each route, step by step:
Where visitors buy Germany eSIMs
Telekom’s own consumer plans are postpaid and want a German address and a credit check, but the prepaid route is open to visitors. MagentaMobil Prepaid starts at 4.95 EUR for 4 weeks with 1 GB of data and 50 minutes, rises through 8 GB at 9.95 EUR, 15 GB at 14.95 EUR and 25 GB at 19.95 EUR, and reaches an unlimited tier at 99.95 EUR for 4 weeks. All include 5G up to 300 Mbit/s and EU roaming.
Telekom eSIM, step by step:
- Order MagentaMobil Prepaid from telekom.de and choose the plan that fits, then receive the starter kit.
- Activate the physical SIM and complete identity verification through PostIdent or VideoIdent with your passport.
- Request the eSIM conversion through Telekom customer service, which issues the profile to your phone.
- No credit check, no term contract, but the eSIM step runs through support rather than a one-tap app install.
Telekom also sells eSIM directly on postpaid MagentaMobil plans, which is the cleanest eSIM path if you can pass the address and credit check.
Local SIM or travel eSIM in Germany?
For the local-SIM route, Vodafone is the easiest of the three big carriers for a visitor. CallYa is the prepaid brand and it offers a free eSIM ordered entirely online.
Vodafone CallYa eSIM, step by step:
- Go to vodafone.de, choose CallYa with eSIM, enter your details and pick a plan.
- Receive an order confirmation with login details and activation instructions by email.
- After arriving in Germany, complete identity verification through PostIdent at any Deutsche Post branch or by VideoIdent in the app.
- Receive the QR code or activation link by email, scan it in your eSIM settings, then top up.
CallYa plans run on four-week cycles: CallYa Start gives 1 GB for 4.99 EUR, CallYa Allnet Flat S gives 25 GB for 9.99 EUR, CallYa Allnet Flat M gives 50 GB for 14.99 EUR, CallYa Black is unlimited for 79.99 EUR, and the Jahrespaket M gives 250 GB for 99.99 EUR per year. All include EU roaming. Without completing identity verification the SIM stays locked, so treat the PostIdent step as the real gate.
The O2 route: a direct prepaid eSIM
O2, run by Telefonica Germany, sells a prepaid eSIM directly through its “Prepaid eSIM for Europe” offer: 20 GB for 9.99 EUR per 4 weeks or 40 GB for 14.99 EUR per 4 weeks, with EU roaming included and speeds up to 300 Mbit/s. After the high-speed allowance is used, O2 keeps you online at up to 1 Mbit/s down and 384 Kbit/s up rather than cutting you off.
O2 eSIM, step by step:
- Order the O2 prepaid eSIM from o2online.de and choose a plan.
- Verify your passport online during sign-up, which O2 supports for foreign passports though some non-EU documents take longer.
- Receive the QR code by email and install it before departure or on arrival.
- No German address is required for the prepaid route, only the identity check.
If you want O2 pricing but plan to stay in cities only, Aldi Talk and blau resell O2 and undercut it further, at the cost of the physical-SIM-first eSIM detour described above. O2 itself is the simpler eSIM path.
What to prepare before buying a German carrier eSIM
- IMEI: dial
*#06# - EID: also from the
*#06#screen, this is the eSIM’s own identifier - Photo ID: passport is the standard document for German identity verification
- A German address or hotel address: required on some carrier routes and for postpaid plans
- A card that works in Germany: some carrier checkouts reject foreign billing addresses
- Wi-Fi: install the profile before you fly, not at the airport
How Germany verifies your identity for a prepaid eSIM
German law requires identification for every prepaid SIM and eSIM, and this is the country-specific rule that catches the most visitors off guard. The methods differ in reliability for a foreign passport.
| Method | How it works | Foreign passport? |
|---|---|---|
| PostIdent at Deutsche Post | Take your passport to any Post branch, staff verify in person | Yes, the most reliable option |
| VideoIdent | A video call through the provider or WebID app | Often limited for non-EU passports |
| eID | The online ID function of an EU or German ID card | EU or German ID only, not a passport |
| In-store at a carrier shop | Bring your passport to a Vodafone, O2 or Telekom shop | Yes, but staff may push a pricier plan |
Budget your first morning for PostIdent if you go the carrier route, or skip it entirely with a travel eSIM.
Using your Germany eSIM in other countries
This is the real cross-border increment for Germany. Because Germany is inside the EU, prepaid plans follow the Roam Like At Home rules, so your German allowance works across the bloc within fair-use limits.
| Carrier | EU roaming included | Watch out |
|---|---|---|
| Telekom MagentaMobil | Yes, EU and EEA, with Switzerland and UK on higher tiers | Switzerland and UK only on some plans |
| Vodafone CallYa | Yes, 45 EU countries | Switzerland is charged separately |
| O2 Prepaid | Yes, EU, EEA, Norway, Iceland, Liechtenstein | Switzerland is not included |
| Aldi Talk on O2 | Yes, EU | Switzerland is not included |
| Lidl Connect on Vodafone | Yes, EU and UK | Check the fair-use data cap |
Switzerland is not in the EU, so nearly every German plan bills it as a separate zone. If your itinerary crosses into Switzerland, plan for that specifically rather than assuming your Germany eSIM covers it.
How do Telekom, Vodafone and O2 compare?
Two questions determine the choice here: how each network performs on your route, and what sort of journey you are making. The benchmarks below deal with speed, and the trip table deals with which network suits you.
Telekom vs Vodafone: which Germany carrier is faster?
All figures below come from Ookla’s Speedtest Intelligence data for Germany, period January to June 2025 (1H 2025), national-level measurements, published in the Ookla Speedtest Connectivity Report for Germany H1 2025.
| Metric | Telekom | Vodafone | O2 |
|---|---|---|---|
| Speedtest Connectivity Score | 78.87 (highest) | 74.77 | 71.28 |
| Speed Score | 68.13 (fastest) | 61.51 | 54.91 |
| Consistency Score | 93.5 (best) | 89.3 | 87 |
| 5G Availability | 57.9% | 68.6% | 72.4% (highest) |
| Video Streaming Score | 81.68 (best) | 79.58 | 78.99 |
| Game Score | 90.62 (best) | 88.31 | 87.24 |
| 5-Star Rating | 3.99 (top) | 2.89 | 3.15 |
Empty cells indicate that Ookla published no value, not that a number was estimated. Two things worth noticing: O2 leads on 5G availability, meaning you sit on 5G most often, while trailing on raw speed, and Telekom’s win is consistency, the share of samples meeting a 5 Mbps down and 1 Mbps up threshold, which is exactly the metric that matters on a rural road. On the same report Telekom was named both Best Mobile Network and Best 5G Network in Germany for 1H 2025.
For country-level context, Cable.co.uk prices 1 GB of German mobile data at about USD 2.14, well below the USD 2.59 global average, and DataReportal counts roughly 78.9 million internet users in Germany at 93.5 percent penetration alongside about 108 million mobile connections. Germany’s networks are mature and affordable by European standards, which is why a travel eSIM rides on solid local infrastructure.
Best Germany eSIM by trip type
| Your plans | Go-to carrier | What makes it the pick | Watch out for |
|---|---|---|---|
| City break in Berlin, Munich, Hamburg, Frankfurt | Telekom | Fastest and most consistent network downtown | Congestion at major events |
| Road trip, Bavaria, Black Forest | Vodafone | Strong rural and highway coverage | Still patchy in deep valleys |
| Budget city stay | O2 | Cheapest, strong in cities | Weak once you leave the city |
| Gaming and video calls | Telekom | Highest Game Score 90.62 and Video 81.68 | O2 trails on both metrics |
| Cross-border EU itinerary | Any plan with EU roaming | Works across the EU at no extra cost | Switzerland excluded on most |
| Business travel | Telekom or Vodafone | Reliable 5G in cities and airports | O2 congests at peak in the Ruhr |
| Long stay or study | O2 or Aldi Talk | Low monthly cost, real savings | Identity verification required |
Telekom vs Vodafone: coverage compared
Germany’s coverage follows population: dense and fast in the city regions, thinning fast along secondary roads and in the mountains. What that means route by route:
| Region | Reality on the ground | Best carrier | Watch out |
|---|---|---|---|
| Berlin and the east | Dense urban 5G on all three, strong between cities | Telekom | Congestion around Alexanderplatz and during big events |
| Munich and Bavaria | Strong city 5G, Alpine resort valleys patchier | Telekom | O2 thins out fast in rural Bavaria and the Alps |
| Rhineland, Cologne, Dusseldorf | 5G on all three, holds along the highways | Telekom | Ruhr conurbation congests at peak hours |
| Hamburg and the north coast | Reliable in cities, coastal roads fade | Vodafone | Baltic Sea stretches and North Sea wind weaken signal, O2 weakest |
| Black Forest and central uplands | Coverage follows the settlements | Vodafone | Deep valleys have no signal, download offline maps |
| Deutsche Bahn ICE corridors | Trains carry WiFi that aggregates all networks, your own eSIM still leans on trackside masts | Telekom or Vodafone | O2 has the largest gaps on rural rail, tunnels drop everyone |
The rural Bavaria and Baltic coast gaps are real: O2 in particular sheds signal on the quieter coastal roads and along the scenic Alpine valley routes, while Telekom and Vodafone hold up better. On the train, ICE WiFi masks the gaps by bonding every network, but the moment you rely on your own eSIM in a tunnel or a remote stretch, the host network is all that matters.
Planning a route that leaves Germany? Compare France eSIM plans if you head west, or Netherlands eSIM plans and Austria eSIM plans for the Benelux and Alpine directions. If your itinerary crosses borders more than once, a Europe eSIM covers every EU country on one profile.
Automatic carrier switching is the part that earns its keep here. A profile that can move between Telekom, Vodafone and O2 covers the regional gaps that any single-carrier plan cannot.
Which APN does each German network use?
The APN screen is the last thing you should need and the first thing worth checking when a data connection dies. Below are the values for all three networks plus their discount brands, when manual entry is genuinely required, and the exact menu paths.
APN values for Telekom, Vodafone and O2 eSIMs
You will only need these if you bought your Germany eSIM directly from a German carrier or a brand on its network. When you run a travel eSIM, the profile carries its own APN, so you should leave those fields alone.
| Carrier or brand | APN | Username | Password |
|---|---|---|---|
| Telekom | internet.t-mobile.de |
blank | blank |
| Vodafone and Lidl Connect | web.vodafone.de |
blank | blank |
| O2, Aldi Talk, blau, otelo | pinternet.interkom.de |
blank | blank |
Leave username and password empty. For O2-based lines, internet is a usable fallback if pinternet.interkom.de does not connect, but the longer string is the current standard. Should a carrier demand extra values, the activation instructions bundled with your profile will spell them out.
When a German line needs the APN typed in
- An older phone that will not pull carrier settings on its own
- A profile added through a manual activation code rather than a QR scan
- A carrier-issued prepaid eSIM whose automatic configuration never completed
- On a travel eSIM this is almost a non-issue, which is the whole point of a managed profile
Where the APN fields live on your phone
- iPhone: open Settings, choose Cellular, select the eSIM line, then Cellular Data Network and type the APN
- Android: open Settings, go to Connections, Mobile Networks, Access Point Names and add a new APN
After saving, restart the phone. If data is still missing, be sure the eSIM, and not your home SIM, is the line picked for mobile data before you touch other settings.
Installing a Germany eSIM step by step
A single pass through this section takes you from clean install to working data, and covers the failure patterns a German network can actually produce, in the order you’ll hit them.
Installing a Germany eSIM
| # | Check | What good looks like |
|---|---|---|
| 1 | Phone is not carrier locked | Carrier Lock in About shows “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 | Install on Wi-Fi at home, the profile connects when you land |
| 5 | Data line and roaming set | eSIM selected for mobile data, data roaming on |
Do step 4 at home. Frankfurt and Munich arrivals halls have congested Wi-Fi exactly when you need it most, and a Germany eSIM profile you install on the ground competes with everyone else’s.
Germany eSIM activation by carrier
Our activation guide covers the ordinary sequence from Add eSIM to switching on roaming. What differs by carrier:
- Telekom: prepaid eSIM is issued through customer service after a physical SIM is active; postpaid eSIM activates at checkout after verification
- Vodafone CallYa: free eSIM ordered online, identity verification by PostIdent after arrival, QR delivered by email
- O2 Prepaid: direct prepaid eSIM, passport verification online, QR by email
- Aldi Talk, Lidl Connect, Otelo: must order and activate a physical SIM first, then convert to eSIM in the portal
- Travel eSIMs: install by QR code, and the same profile roams onto whichever of Telekom, Vodafone or O2 is strongest
Germany eSIM failure: four fixes
General activation errors, a profile that will not download, a scan that fails, an eSIM that installs but never registers, are covered in our activation error troubleshooting guide. The four failure patterns below are specific to Germany.
A. The eSIM will not install
- Confirm Carrier Lock shows “No SIM restrictions”
- Check the QR code is clear and has not yet been scanned, since most work only once
- The carrier can confirm whether the profile is awaiting release after verification
B. Installed, but no signal bars
- Re-check the lock status
- Settings, Cellular, Network Selection, select Telekom, Vodafone or O2 manually instead of automatic
- Reset all network settings, then reboot again
C. Signal bars, but no internet
- Check the APN against the table shown above
- Make sure the eSIM is the chosen data line, not the SIM from home
- Check you have not exhausted your allowance, O2 throttles to 1 Mbit/s rather than stopping, and other prepaid brands enforce a fair-use cap
D. “SOS” or “Emergency calls only”
- Confirm the eSIM is switched on in the SIM manager
- Turn off or remove any other active SIM or eSIM profile
- Reboot and reset network settings
- As a final step, delete the profile and reinstall it from a new QR code
What to gather before contacting Germany eSIM support
| What we’ll ask for | Where to look |
|---|---|
| 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, your eSIM line |
| Steps already tried | Keep a short list |
Germany eSIM FAQ
Can I buy a prepaid eSIM directly from Telekom as a visitor?
Technically yes, but not in one tap. Telekom’s prepaid eSIM is issued through customer service after you activate a physical MagentaMobil Prepaid SIM and complete identity verification. Telekom’s postpaid MagentaMobil plans offer eSIM directly at checkout, but those want a German address and a credit check. For most visitors the prepaid route is the realistic one.
Does a Vodafone eSIM require a German address?
For CallYa prepaid, no fixed address beyond a contact point is needed to order, but you must complete identity verification, usually PostIdent at a Post branch, after arrival. Vodafone is the visitor-friendliest of the big three because the eSIM itself is free and ordered online. If you want the Vodafone network without that step, a travel eSIM on the Vodafone network is the alternative.
Can international visitors buy an O2 eSIM?
Yes. O2 sells a prepaid eSIM directly through its website, with passport verification handled online during sign-up. Plans start at 20 GB for 9.99 EUR per 4 weeks and include EU roaming. O2 is a strong choice for visitors who want a real German eSIM without the physical-SIM-first detour that Aldi Talk and Lidl Connect impose.
Which Germany network is best overall?
Vodafone, on the balance of evidence. Telekom leads on consistency and raw speed, but Vodafone holds signal better along highways and in smaller towns, and O2 is the weakest outside cities. If your trip leaves the major urban regions, favor Telekom or Vodafone, and download offline maps for the Black Forest and Alpine valleys regardless.
Which Germany carrier is the cheapest?
O2 and its discount brands. O2’s own prepaid eSIM starts at 20 GB for 9.99 EUR per 4 weeks, Aldi Talk and blau resell O2 at similar or lower prices, and Lidl Connect resells Vodafone from about 8.99 EUR for a four-week bundle. Telekom costs the most. Match the brand to your coverage need rather than buying the cheapest and losing signal on day two.
Is identity verification required for a Germany eSIM?
Yes, without exception. German law requires identification for every prepaid SIM and eSIM, so a passport check through PostIdent, VideoIdent, eID or an in-store visit is mandatory before the line goes live. This is the single biggest difference from a travel eSIM, which needs no German verification.
Device checks: IMEI and EID in Germany
The phone must be unlocked and support eSIM. Check both in one pass with the eSIM compatibility page, which covers EID support and the band question, including the n28 and n78 5G bands that many international handsets lack. If you would like to see what happens during setup first, read what happens during eSIM activation.
Does a German prepaid eSIM work in the EU?
Yes. Because Germany sits inside the EU, prepaid plans follow Roam Like At Home, so your allowance works across the bloc within fair-use limits. The catch is Switzerland, which is not in the EU and is billed separately by nearly every German provider, so plan for it explicitly on a Switzerland day trip.
Should I buy from a German carrier or a travel eSIM?
Direct means one network, carrier-issued provisioning, and a passport check, and in exchange you get a real German number and unlimited domestic calling. A travel eSIM means instant delivery, no paperwork, automatic switching between Telekom, Vodafone and O2, and a fixed upfront price. Short trip, travel eSIM. For trips measured in months — or if a local number matters — buy from a carrier directly.
Do budget brands like Aldi Talk sell a real prepaid eSIM?
They sell prepaid plans on O2 or Vodafone, but the eSIM is not instant for new customers. Aldi Talk, Lidl Connect and Otelo require you to order and activate a physical SIM first, then convert it to eSIM in the account portal, and the same identity check still applies. They are cheap, not frictionless.
How do I unlock my phone for a German eSIM?
The lock is held by your home carrier, not a German one, because Germany has no mandatory unlock law. Contact the carrier the phone is locked to and request an unlock; paid-off devices clear within hours at no German fee. Check that status at Settings, General, About, Carrier Lock before you board your flight.
What if my Germany eSIM will not activate?
Work the four Germany-specific patterns above in order, lock status, network selection, APN and data line, then profile reinstall, and if it still fails, the wider error catalogue in eSIM problem-solving guide covers the rest. Keep your EID, order number and a screenshot on hand before you reach out to support.
