Bottom line: Germany is the European country where the SIM card is a regulated identity document and the handset is the real constraint. Under section 172 of the German Telecommunications Act a provider must identify the customer before the mobile service is activated, and the Federal Network Agency — not the shop — decides which verification procedures are acceptable. That is why a German prepaid card cannot be bought and used the way a tourist SIM is bought in Asia: you either stand in a shop with your passport or you sit through a video-identification session. The second constraint is older hardware. Germany switched its 3G networks off in 2021, and all three network operators have now committed to switching off 2G as well — Telekom by the end of June 2028, Vodafone by the end of September 2028, Telefónica by the end of 2028 — so a phone without Voice over LTE is on a countdown. Against that, coverage is not the problem: in the Federal Network Agency’s nationwide measurement week of 24 June to 1 July 2026, 98 percent of nearly 20 million measurement points had 4G or 5G, and almost 70 percent were on 5G. And if your everyday SIM is issued anywhere in the EU or EEA, you already have the right to use it in Germany at domestic prices until 30 June 2032 — you should buy nothing at all.

This page was rebuilt from primary material in September 2026: the Federal Network Agency’s own pages on prepaid identification procedures and on the 2G switch-off, its December 2025 mobile-network monitoring release and its July 2026 measurement-week release, the consolidated text of the EU roaming regulation, the European Commission’s notice on the Entry/Exit System, and the GSMA specification that every eSIM profile is issued against. It is deliberately not a ranked price table. In Germany, price per gigabyte is not what goes wrong. Eligibility and hardware are.

Section 172: why nobody sells you an anonymous German SIM

Most English-language travel writing about Germany still describes buying a prepaid card as an errand you run at a supermarket checkout or an airport kiosk. The card is indeed sold there. What is no longer sold there is the ability to use it without being identified first.

The obligation sits in section 172 of the Telekommunikationsgesetz, the German Telecommunications Act. The Bundesnetzagentur — the Federal Network Agency, Germany’s telecoms regulator — publishes the working rules for it. Two features of that arrangement matter to a visitor, and neither is obvious from the shelf in the shop.

• The check happens before activation, not at the till. The card in the blister pack is inert. It becomes a working service only once the provider has recorded identity data from an accepted document. Buying the packaging and boarding a train does not give you a working number.
• The regulator, not the retailer, decides what counts as identification. Section 172(2) TKG gives the Federal Network Agency the job of determining which procedures are suitable beyond the direct presentation of an identity document. Video identification is one of them. The regulator also set up a conformity-assessment regime for those procedures, and because no conformity-assessment body has been accredited yet, it announced in its Official Gazette (Amtsblatt 10/2026, notice no. 86/2026) that it will not open supervisory proceedings against a provider purely for a missing conformity certificate until 1 May 2027. In other words the framework is still being built out, and providers are cautious rather than relaxed about who they let through.

The practical consequence for a short visit is a fork with only two prongs. Either you spend part of a working day on identification — a branded shop, a passport, sometimes a German address field that a hotel booking does not satisfy, or a video call in which an agent reads your document on camera — or you arrive with a profile that was issued outside Germany and therefore never becomes a German subscriber contract at all. A travel eSIM belongs to the second category: it is a roaming profile, so the German identification duty does not attach to it.

That is the entire argument for and against a German card, and it has nothing to do with tariffs. If you are staying for months, want a German number for deliveries, banking or a rental contract, and can spare the appointment, a German prepaid card is worth the friction. If you are here for a week of meetings or a Christmas-market weekend, the friction is the whole cost.

If your SIM is European, stop reading and buy nothing

This is the single most common wasted purchase we see. Travellers with an Italian, Spanish, Polish or Irish contract land in Frankfurt and buy a German data package they were never going to need.

Regulation (EU) 2022/612 is the current roaming regulation. It carries the “roam like at home” regime forward to 30 June 2032, and it went further than its predecessor by adding a quality-of-service obligation: when you roam, you are entitled to the same service quality you get at home where the visited network supports it, which in practice means that a home 5G plan should give you 5G in Germany rather than being throttled to a legacy tier. Operators may still apply fair-use limits designed to stop permanent roaming — that is aimed at people who live in one country on another country’s tariff, not at a fortnight’s holiday.

So the decision tree starts here, before any comparison of providers: if your everyday SIM was issued in an EU or EEA country, you already have the cheapest option in your pocket. The rest of this page is for everyone else — visitors from the United Kingdom, the United States, Canada, Japan, Korea, Australia, India, Brazil and everywhere else outside that zone.

The hardware trap: 3G is already gone, 2G is on a clock

This is the part of German connectivity that actually strands people, and it is almost absent from travel guides because it looks like a technical footnote rather than a travel tip.

According to the Federal Network Agency’s public briefing on the 2G switch-off, the German mobile network operators shut down their 3G networks in 2021. There is no UMTS fallback in Germany any more. The 2G layer that has been quietly carrying voice calls and machine traffic ever since is next, and each operator has now named a date:

The reason this matters before 2028 is that it explains a failure people already experience today. The same regulator page notes that 2G still reaches more than 99 percent of Germany’s land area, against more than 97 percent for 4G and more than 93 percent for 5G. That last sliver of 2G is exactly where a handset without Voice over LTE ends up when it needs to place a call — and if the roaming agreement behind your travel profile does not carry VoLTE, calls fall back to a layer that is being dismantled. Data keeps working; the call does not connect. Travellers report this as “my eSIM does not work” when what has actually failed is one specific service on one specific radio layer.

The regulator’s own advice to consumers is to check that the device supports 4G and 5G on the German frequency bands, and to ask the provider or the manufacturer where the answer is unclear. For a visitor that translates into two concrete checks before departure, both of which take a minute:

• Is VoLTE switched on? On most handsets it is a toggle in the mobile-network settings, sometimes labelled “4G calling” or “HD Voice”. On phones bought from a carrier outside Europe it is occasionally locked to that carrier’s own network, which is the worst case: the toggle exists but does nothing while roaming.
• Is your travel profile data-only? Most travel eSIMs are. That is not a defect — it sidesteps the voice problem entirely, because messaging and calling then run over the internet. But it does mean you cannot receive a German landline call, and you should not rely on it for a bank’s SMS one-time password. Keep your home SIM installed alongside the eSIM for SMS, and use the eSIM for data.

What the coverage figures actually say

Germany has a reputation among travellers for bad mobile coverage, largely earned in the 2010s and largely out of date. Two independent measurements from the regulator put numbers on where it now stands, and they are worth separating because they measure different things.

Area coverage. The Federal Network Agency’s mobile-monitoring update of 15 December 2025 reported that, as of October 2025, around 95 percent of Germany’s land area was covered by 5G, up from about 93 percent a year earlier, and that mobile broadband — 4G or 5G — reached roughly 98 percent of the country. Per operator, 5G area coverage stood at approximately 87 percent for Deutsche Telekom (83 percent in 2024), 76 percent for Telefónica (72 percent) and 75 percent for Vodafone (71 percent). The gap between Telekom and the other two is the single most useful number on this page for anyone travelling outside the cities, because a travel eSIM’s usable coverage is decided by which host network its roaming agreement lands on.

Experienced coverage. Area percentages flatter a country with a lot of empty land, so the regulator also runs a crowd-sourced measurement week. The first results of the second nationwide measurement week, published on 9 July 2026, cover 24 June to 1 July 2026, during which more than 60,000 users recorded close to 20 million measurement points — against roughly 2 million per week before the campaign. Of those points, 98 percent had 4G or 5G. The share on 5G rose to almost 70 percent, where the previous year’s exercise had found 4G and 5G at comparable shares. Under one percent of points were on 2G, a fall of 1.24 percentage points year on year, and at fewer than one percent of points no coverage was recorded at all — unchanged from the year before.

One caveat the regulator itself flags by publishing the regional breakdown: participation is not evenly distributed. North Rhine-Westphalia contributed around 4.2 million measurement points, Bavaria 3.2 million and Lower Saxony 2.6 million, while Bremen and Saarland each came in under 200,000. Crowd-sourced measurement is densest where people are densest, which is precisely not where the gaps are. Treat “98 percent of measurement points” as a statement about the places Germans actually stand, not about the Eifel plateau or the Mecklenburg lake district on a Tuesday morning.

For a traveller the honest summary is: in cities, along the ICE corridors and in the tourist regions, you will not think about coverage. In the low-density east, in forested valleys in the south-west and on regional rail lines, you will occasionally drop to nothing — and a downloaded offline map is worth more than any tariff comparison.

The border changed in 2026, and it changes your first hour

Connectivity planning for Germany now has to account for something that did not exist two years ago. The European Union’s Entry/Exit System registers non-EU nationals crossing the external Schengen border for short stays. It started operating on 12 October 2025 and, according to the European Commission, became fully operational on 10 April 2026, replacing passport stamps with a digital record that includes the traveller’s facial image and fingerprints and is retained for three years. Registration is heaviest on the first crossing; afterwards it is a biometric check.

Why does that belong on a connectivity page? Because it changes the arithmetic of arrival. The first EES registration adds time at the border, and the member states were given the option to suspend full operation temporarily to manage congestion, which means queue length at Frankfurt or Munich is not predictable from one month to the next. If your plan was “land, clear passport control, find a shop, buy a SIM, then message the person collecting me”, that plan now has a variable-length gap in the middle of it. A profile that is already installed and activates on landing removes the dependency entirely. This is not a sales argument for eSIM technology in the abstract; it is an argument about ordering. Whatever you use, have it working before you join the queue.

So: German card, or profile from home?

Stated as a decision rather than a ranking, because for most visitors this is a two-line question.

Before you fly: a five-item check

1. Confirm your handset is eSIM-capable and carrier-unlocked. The GSMA’s eSIM pages are the authoritative record of which device variants implement consumer remote SIM provisioning. Regional variants of the same model differ.
2. Turn VoLTE on and verify it is not carrier-locked. Germany has no 3G, and 2G is scheduled to go by 2028.
3. Check whether you are already covered. An EU or EEA SIM needs nothing. Some UK, US and Japanese plans include EU data too — read the plan before buying a second one.
4. Install and test the profile at home. Install on your own wi-fi, then leave it disabled until you land. Installation needs connectivity; that is the one thing you will not have at the gate.
5. Keep your home SIM in the phone. Bank one-time passwords, airline rebooking texts and two-factor codes still arrive by SMS to your own number.

FAQ

Can a tourist buy a prepaid SIM card in Germany?

Yes, but not anonymously and not instantly. Section 172 of the German Telecommunications Act requires the provider to identify the customer before the service is activated, and the Federal Network Agency determines which verification procedures are acceptable. In practice that means presenting a passport in a branded shop or completing a video-identification session. The card sold in a supermarket is inert until that step is done.

Does a travel eSIM bought before arrival need German registration?

No. A travel profile issued outside Germany is a roaming arrangement, not a German subscriber contract, so the German identification duty does not attach to it. That is the structural difference between the two options, and it is why one requires an appointment and the other does not.

I have an EU SIM. Do I need anything for Germany?

No. Regulation (EU) 2022/612 extends roam-like-at-home to 30 June 2032 and adds a quality-of-service entitlement, so an EU or EEA SIM works in Germany at domestic prices and, where the German network supports it, at home-equivalent quality. Fair-use limits exist to prevent permanent roaming, not to restrict ordinary travel.

Will my old phone stop working in Germany?

For data, if it supports 4G on German bands, no. For calls, possibly. Germany’s 3G networks were switched off in 2021, and Telekom, Vodafone and Telefónica have committed to switching off 2G by the end of June 2028, the end of September 2028 and the end of 2028 respectively. A handset without working Voice over LTE currently depends on the 2G layer for calls, and that layer is being dismantled.

Which German network has the best coverage?

By land area on 5G as of October 2025, the Federal Network Agency put Deutsche Telekom at approximately 87 percent, Telefónica at about 76 percent and Vodafone at about 75 percent. In cities the practical difference is small. Outside them it is not, and since a travel profile’s coverage is decided by the host network its roaming agreement uses, that is worth checking before you buy rather than after.

Does the EU Entry/Exit System affect my phone or my SIM?

Not directly — it is a border-registration system, not a telecoms one. It affects the sequence of your arrival. Since it became fully operational on 10 April 2026, non-EU travellers are registered biometrically instead of receiving a passport stamp, and first registration takes longer than a stamp did. Anything you were planning to do after passport control and before contacting someone should be moved to before departure.

Will I have signal on a regional train or in the Alps?

Often, but not reliably. The regulator’s June–July 2026 measurement week found 98 percent of measurement points on 4G or 5G, with fewer than one percent showing no coverage — but the measurements are densest where the population is densest. Regional rail lines, forested valleys and the low-density east are where the remaining gaps sit. Download offline maps and your tickets before you leave a city.
