Germany is one of Europe's big travel hubs: city breaks in Berlin, Munich and Hamburg, Christmas markets, beer gardens, the Rhine valley and the Alps on the southern edge. For travellers with an EU SIM, the phone question is simple, because Germany is covered by Roam Like at Home. Visitors from the United States, the United Kingdom or Asia usually pay roaming by the day.
What surprises visitors is that a large, wealthy country still has gaps in mobile coverage, and that one of its nine neighbours sits outside EU roaming.
Key facts for Germany
- EU roaming: covered by Roam Like at Home
- Local networks: T-Mobile (Telekom), Vodafone, O2 (depending on the plan)
- Emergency numbers: 112 for fire and ambulance; police 110
- Embassies: in Berlin, with consulates in Munich, Frankfurt, Hamburg and other cities
Deutsche Bahn: data on the move
The DB Navigator app sells tickets, shows platform changes and holds your ticket on the phone, and long-distance ICE trains offer Wi-Fi on board. Coverage along the main lines has improved, but on rural stretches, in tunnels and in hilly regions the signal still drops for a while. Download your ticket and connection details before boarding, so a dead spot does not leave you without them at the ticket check.
For local and regional transport, the Deutschlandticket is a monthly subscription valid on buses, trams, the U-Bahn and regional trains across the country. It is sold digitally in apps; if you only need it for one trip, cancel it before the next month starts.
The countryside and its dead spots
Germans have a word for places without signal: Funkloch. Cities and motorways are well covered, but parts of the countryside, forests and valleys in regions such as the Black Forest, the Harz or the Bavarian Forest can still have weak or no coverage. Save offline maps and your accommodation's address before driving into rural areas.
The Swiss border and Lake Constance
Germany's neighbours are all in the EU except Switzerland. Around Lake Constance, near Basel and along the Rhine, a phone can pick up a Swiss network across the water or the border, and an EU plan may charge for it. The German enclave of Büsingen, surrounded by Swiss territory, is a classic case. If you stay near the border, choose a German network manually in your phone's settings.
Paying: cards and cash
Cards and phone payments are accepted in most shops and restaurants, but some bakeries, small cafés and beer gardens still prefer cash. Carry a little cash for those places.
Getting connected
EU SIM: Germany counts as home for roaming purposes. A travel eSIM helps if your tariff includes little data abroad or your trip continues into Switzerland.
SIM from outside the EU: install a travel eSIM before departure. It starts its validity at the first connection in Germany, your usual number keeps receiving texts, and train, map and messaging apps run on its data.
German prepaid SIMs must be registered with an identity document before they work.
Consular protection: who to call in Germany
- 112 reaches the fire service and ambulances; 110 is the police.
- Embassies are in Berlin, and many countries have consulates in Munich, Frankfurt, Hamburg and other large cities. The Telcomia app shows yours, with address and phone.
- Emergency phrases in German are ready to show on screen in the app.
