How to Use a Phone in Germany Without German SIM Registration
The German SIM you buy does not work when you buy it
Germany is stricter about SIM cards than most of its neighbours, and the way it is stricter catches people out. You can walk into a shop, pay for a prepaid card, walk out with it in your pocket, and still have no service. The card stays inactive until your identity has been checked and recorded. A germany esim plan with a number included sidesteps that process entirely, because the rule applies to German SIM cards and a roaming line is not one.
That is the short version. The longer version is worth knowing before you travel, because the verification step is not always something you can finish at the counter.
TL;DR
Since July 2017 every SIM card sold in Germany – prepaid included – must be linked to a verified identity before it can be activated. The check is set out in section 172 of the German Telecommunications Act and the permitted methods are tightly defined: an in-store identity check, a post office procedure, a video call, or an electronic identity document. A foreign passport is accepted in principle. None of this applies to a line that is roaming in Germany rather than issued there, which is why an eSIM bought before you travel works the moment you land.
What section 172 actually requires
The German rule is not a shop policy. It is federal law. Section 172 of the Telecommunications Act requires the operator to collect and verify the subscriber’s identity before the service is activated, and the text of the provision sets out which documents and electronic identity procedures satisfy it.

The practical consequence is the part travellers miss. In France you show a passport at the till and leave with a working line. In Germany the purchase and the activation are separate events. You buy the card, then you complete a verification procedure, and only then does the number come alive. If you are buying from a counter staffed by someone who can check your document on the spot, those two steps can happen together. If you are buying from a supermarket shelf or a vending machine, they cannot.
The regulator defines which verification methods are acceptable. In practice the routes are an identity check in a shop, a post office identification procedure, a video identification call, or an electronic identity document read by an app. Each of them works. Each of them also takes time, and the video route in particular depends on staffing hours and a decent connection, which is an awkward dependency when the reason you want a phone is that you have just arrived somewhere unfamiliar.
The four ways Germany lets you prove who you are
The law says the identity has to be verified. The regulator says how. In practice there are four routes, and the difference between them is almost entirely about where you have to be and how long it takes.
The first is an identity check in a shop. A member of staff looks at your document, records what the law requires, and the line is activated. This is the fastest route and the one most travellers assume is the only one. It depends on buying somewhere staffed by a person who can do it, which rules out supermarket shelves and vending machines.
The second is a post office identification procedure. You take the document to a counter, the clerk verifies it against the operator’s request, and the activation follows. It works reliably and it costs you a trip to a post office during opening hours, which is a real constraint on a short visit.
The third is a video identification call. You hold your passport up to a camera while an agent checks it. It is convenient in principle because you can do it from your accommodation, and less convenient in practice because it depends on the agent’s working hours and on a connection good enough for the call – and you are trying to arrange it on a phone that does not yet have service.
The fourth is an electronic identity document read by an app, which is the smoothest option if you hold a document that supports it. Most visitors do not.
None of these is onerous in isolation. What makes them matter is the ordering: they all sit between you and a working phone, on the day you arrive, in a country you may not know well. If your plan for the first evening involves calling an apartment owner or finding an address, that is the wrong moment to discover the verification queue.
Why your own phone may be the simplest answer, until the bill arrives
If you are visiting from inside the EU, your home plan travels with you and roam-like-at-home rules mean you are usually billed as though you never left. For an EU resident on a short trip to Germany, doing nothing at all is frequently correct.
From outside the EU the picture is different. A UK, US, Canadian or Australian plan in Germany is an international roaming situation, and the daily rates add up quickly on a trip of any length. Your own carrier’s travel pass is the convenient option and rarely the cheap one. how eu roaming rules actually work covers where the free-roaming boundary sits and who falls outside it.
Keeping both lines running is the usual answer, and running two lines on one handset covers the settings worth checking before you leave – which line sends your messages, and which one carries data.
There is also a reachability question that has nothing to do with cost. A number with a foreign dialling code marks you as not-here. German businesses, landlords and agencies call back domestic numbers more readily than international ones, and some national SMS systems are scoped to the country they serve, so a confirmation code can simply fail to arrive on an overseas number even when the signup accepted it.
What an eSIM changes
An eSIM bought before you travel is a line issued elsewhere and used in Germany under roaming. That is the whole mechanism, and it is why the German registration requirement does not reach it: section 172 governs SIM cards issued in Germany, and this is not one.

Europe Number sells those plans from 20GB up to 120GB. The data works in Germany on local networks. The number that comes with it is a French line, not a German one, and it is worth being precise about that because it changes what the product is good for.
That is the same line Europe Number runs everywhere else, which is why it is sold as an esim with a real european phone number rather than as a country product. A French number receives calls and SMS normally while you are in Germany. It clears verification on services that reject app-based numbers. What it does not do is make you look German to a German business – for that you would need a German line, with the registration that comes attached. If a local dialling code specifically matters to you, buy a German SIM and complete the verification. If what you need is a working phone, a number that reaches you, and no paperwork, the roaming route is simpler.
Which route suits which trip
| Route | German registration? | Works on arrival? |
|---|---|---|
| German prepaid SIM | Yes – identity check required before activation | Only once verification completes |
| Your own plan, roaming | No | Yes, at your carrier’s roaming rates |
| eSIM bought before you travel | No – not a German SIM | Yes, installed in advance |
If Germany is one stop on a longer route, the same line keeps working across the border, which is the point of one plan that covers several countries rather than a local card in each one. Buying a SIM in every country you pass through means repeating the registration question in every country that has one.
Setting it up before you go
Install over wifi at home. Scanning the code does not start anything – the plan begins when you activate, which you can leave until the day you travel. On arrival the line attaches to a German network and you are reachable without having visited anything.
Keep your home SIM in place alongside it. Modern handsets run two lines at once, so your usual number stays active for the people who already have it while the second line handles everything local – calls back from a hotel, a code from a booking site, a driver trying to find you.
It is worth doing that configuration at home rather than at the airport. The defaults are not always what you want, and changing them is a two-minute job on a familiar wifi connection and an irritating one on a strange network.
What this does not solve
The line is temporary. The number is released when the plan ends, so anything you will need to reach months from now should sit on a number you are keeping, with email as the fallback.
Keep your bank on your home number. Banks tie security messages to the number already registered to your identity, and a travel line is the wrong tool for that.
And it is not a German address. It will not satisfy an Anmeldung, a residence registration, or any form that wants somewhere you live. Those are separate problems with separate paperwork, and no SIM of any kind solves them.
Frequently Asked Questions
Do I need to register a SIM card in Germany?
Yes, if it is a German SIM card. Since July 2017 every SIM sold in Germany, prepaid included, has to be linked to a verified identity before it can be activated. The requirement sits in section 172 of the Telecommunications Act and applies to the operator, not just the shop.
Can I use a phone in Germany without German SIM registration?
Yes. The requirement applies to SIM cards issued in Germany. A line roaming in Germany – your own plan from home, or an eSIM bought before you travel – is not a German SIM, so the registration process does not apply to it.
What identification does Germany accept for a SIM card?
Official identity documents are accepted in principle, foreign passports included. What matters as much as the document is the procedure: the check has to be done one of the defined ways, which in practice means an in-store identity check, a post office identification, a video call, or an electronic identity document read by an app.
Does a Europe Number eSIM give me a German phone number?
No, and it is worth being clear about it. The number is a French line that works across 39 European destinations including Germany. It takes calls and SMS normally while you are there. It will not show a German dialling code, so if a local number specifically matters to you, a German SIM with its registration is the right answer.
Will my own phone work in Germany?
Almost certainly, on roaming. If your plan comes from another EU country, roam-like-at-home rules usually mean you are billed as though you were at home. From outside the EU it is international roaming, and the daily rate is what sends most travellers looking for something else.
How long does the number last?
For the length of the plan. The number is released when the plan ends, so anything you will need months from now should also be reachable by email or on a number you are keeping.
