Germany eSIM

Germany's cities are well covered, but the countryside still has dead spots, and on ICE trains you'll notice them. A German prepaid SIM also needs an ID check by law before it works, so the simplest Germany eSIM, whether you land at Berlin, Munich or Frankfurt, is one you installed at home; if your SIM is from an EU country, it already roams in Germany like at home.

What a week of data costs in Germany

Prices for 7 days of data, checked on 2 November 2026. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. T-Mobile and O2 customers may need nothing extra for a short trip, though 256 kbps is slow for maps and photos. A Turkish line on a weekly pass gets just 1 GB, which a day of maps and messages can use up.

If your SIM is from the EU, it already roams like at home in Germany, as long as you spend more time at home than abroad. UK plans aren't part of that system any more, which is why the UK rows above carry charges.

Landing at Frankfurt, Munich, Berlin BER, Düsseldorf or Hamburg

Switch the kimsim line on as the plane taxis to the gate and turn on Data Roaming for that line only. Then walk through passport control, collect your bags and go through customs. Your first job is usually a train ticket, and with data already working you can buy it in DB Navigator on the way to the platform.

Entry rules. Since 12 October 2025, the EU's Entry/Exit System records non-EU visitors' fingerprints and a photo at the Schengen border, and it has been fully in place since 10 April 2026. Expect a longer queue the first time. ETIAS, the €20 travel authorisation for visa-free visitors, is not in operation yet; the official site says the EU will announce the start date several months ahead. So don't pay any website that offers you an ETIAS today. British visitors can stay up to 90 days in any 180 across Schengen, and your passport must have been issued less than 10 years before you arrive and expire at least 3 months after you leave.

Into the city:

• Frankfurt (FRA): S8 and S9 S-Bahn trains leave the regional station under Terminal 1 every 15 minutes in the daytime. ICE trains use the separate long-distance station.
• Munich (MUC): the S1 and S8 take turns, so a train leaves about every 10 minutes, and it's about 40 minutes to the main station.
• Berlin Brandenburg (BER): the FEX Airport Express reaches Berlin Hauptbahnhof in about 23 minutes, every 15 minutes, and the S9 and S85 S-Bahn lines run every 20 minutes. BER is in fare zone C, so buy an ABC ticket.
• Düsseldorf (DUS): the SkyTrain takes you to the long-distance station in under seven minutes. The S11 leaves from its own station below the terminal, and the U80 reaches the main station in about 18 minutes.
• Hamburg (HAM): the S1 runs about every 10 minutes and takes about 25 minutes to the main station. The station is reached straight from arrivals in Terminals 1 and 2.

Networks and coverage

Germany has four mobile networks: Telekom, Vodafone, O2 (Telefónica) and 1&1, the newest. Telefónica bought E-Plus in 2014 and merged the two networks by 2017, so E-Plus is now part of O2. 1&1 finished moving its 12 million mobile customers onto its own network in November 2025, and it uses Vodafone's network where its own doesn't reach yet. Your phone shows the German operator's name, not kimsim. The Germany plan uses Vodafone and O2, not Telekom.

Where coverage thins. The regulator, the Bundesnetzagentur, counted 2.10% of Germany's land area as "white spots" with no 4G or 5G from any network, and almost 14% as "grey spots" covered by only one network. That second figure matters for a travel eSIM: if the one network in a valley is Telekom, a plan on Vodafone and O2 has nothing to join there. The Bundesnetzagentur's coverage map shows each network's outdoor coverage, based on the operators' own data, and its Mobilfunk-Check app lets you report a Funkloch, a dead spot.

Coverage is generally strong in cities and along motorways. Expect gaps in forests, deep valleys, the Alps and on rural rail lines. The networks your plan uses are listed above.

Berlin, Munich and the regions

• Berlin: generally dense coverage on the street. Big old buildings and basement bars can be weak indoors, so step outside to load a map.
• Munich and Oktoberfest: the Wiesn is one of the busiest places in Europe for a phone network. Telekom alone carried 299,138 GB over the 2025 festival, using ten temporary masts plus three sites inside beer tents. In 2026 it set up 14 temporary sites. Even so, agree a meeting point before you go into a tent, and don't count on video calls inside.
• Bavaria and the Alps: fine in Garmisch-Partenkirchen and Berchtesgaden, patchier on hiking trails and in side valleys. Salzburg and the Austrian Tyrol are close, so watch which country your phone has joined.
• The Black Forest: good in Freiburg and Baden-Baden. Between villages and on forest roads, expect stretches with no signal. Download an offline map before you drive.
• The Rhine valley: generally usable in the towns between Koblenz and Mainz. The steep sides of the gorge can block signal on the river and the riverside railway.
• Hamburg and the north: strong in the city and the port. On ferries to the North Sea islands, signal can fade out at sea.
• Christmas markets: busy squares in Nuremberg, Cologne, Dresden and elsewhere can get crowded networks on weekend evenings, much like a festival.

This is general guidance, not a coverage map. If your plan offers both networks and one is weak where you are, switch network by hand.

Trains, the Deutschlandticket and getting around

• ICE and IC trains: book in DB Navigator, which also sells U-Bahn, tram and bus tickets in many cities. Wi-Fi on ICE trains is free in both classes, but Deutsche Bahn says it uses the mobile networks along the line, so speed depends on them. Save tickets offline before you board.
• The Deutschlandticket covers local buses, trams, U-Bahn, S-Bahn and regional trains across Germany for €63 a month, rising to €66.80 from 1 January 2027. It isn't valid on ICE, IC or EC trains. It's a subscription and a phone ticket only, shown in DB Navigator. Cancel by the 10th of the month and it ends at the end of that month; cancel later and you pay for the next month too. For a stay of a week or more, it can replace a pile of city tickets, but only if your phone has data for the ticket.

Apps worth having

• Taxis and rides: Uber works in Berlin and Munich. Bolt runs in Berlin, including a taxi option. FREENOW books taxis in Germany and across Europe. Set accounts up at home, because sign-up can send a code to your usual number.
• Maps: Google Maps works for public transport routes. Download offline areas for the Black Forest, the Alps and any rural drive.
• Payments: cards are widely accepted, but small bakeries, kiosks, beer gardens and market stalls may still prefer cash, so carry some euros. Some banks send a text code to approve a new device, so keep your home line on for texts with its roaming off.
• WhatsApp: many hosts and guides message you here. Keep your WhatsApp number working abroad.

SIM and phone rules

German law, § 172 of the Telecommunications Act (TKG), says a prepaid provider must check your name and date of birth against an ID document, such as a passport, before it switches the line on. In practice that means a check by video call, an app or in person. Vodafone, for example, accepts a passport on a video call with an agent, in the POSTIDENT selfie app or at a post office. You need internet for the first two, which is awkward if the SIM is your internet.

A travel eSIM installed at home skips the ID check and the shop. It's data only, so your home number stays in the phone for calls and texts.

Common mistakes

• Counting on ICE Wi-Fi. It uses the same mobile networks outside, so it slows down in the same gaps. Save tickets and maps before you board. When data is slow
• Leaving Data Roaming on for your home line. For non-EU SIMs, that's where daily charges start. Roaming goes on for the kimsim line only. Why roaming goes on for the kimsim line only
• Starting the plan on a change of planes. Frankfurt and Munich are big hubs. If you're only connecting there on the way to another country, keep the kimsim line off, or its days can start. If your plan started early
• Day trips to Salzburg, Basel, Strasbourg or Prague. That's a new country with new networks, and a Germany plan won't work there. Look at Austria, Switzerland, France or Czechia, or a regional plan. How regional plans work
• No way to call for help. In Germany, 112 is for an ambulance or the fire service, and 110 is the police. A data-only eSIM can't dial either, so use your home line or any local phone.

How we put this page together

We checked German law, the Bundesnetzagentur, Deutsche Bahn, the airports' own pages, carriers' roaming and prepaid price pages, EU and UK government sites and the other sources noted above on 1–2 November 2026. AT&T's and T-Mobile's pages block automated checks, so we read their prices from the pages' search listings. We haven't measured speeds or coverage in Germany ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
