Coverage and network

Coverage above and below Berlin

Germany mobile networks

All three German operators cover Berlin thoroughly with 5G. Germany's reputation for patchy mobile coverage is a rural and rail problem rather than a big-city one - in Berlin the network is not what you will complain about.

O2T-MobileVodafone

Berlin, specifically

  • Mitte, Kreuzberg, Neukölln, Prenzlauer Berg: Consistent 5G. The wide streets and low blocks help.
  • U-Bahn and S-Bahn: Coverage has been rolled out across the network and most lines now hold a signal in the tunnels, which was not true a few years ago. Older deep sections can still drop between stations.
  • Tempelhofer Feld and the big parks: Fine. An old airfield with nothing to block anything.
  • Berghain queues and festival weekends: Large crowds standing in one place for hours congest a single cell. Expect slow uploads rather than no service.
  • Out to Potsdam and Brandenburg: The S-Bahn corridor and Potsdam itself are well covered. Rural Brandenburg is where Germany's coverage reputation comes from - real gaps between villages.

Germany, and the EU

The plan covers all of Germany, and as an EU member state the same terms carry into Poland, Czechia or the Netherlands at domestic rates.

Frequently asked questions

Coverage

Where to buy a SIM card in Berlin?

Telekom, Vodafone and O2 have shops on Alexanderplatz and along Friedrichstraße, and the supermarket chains sell prepaid starter packs. Buying the pack is the easy part - activating it is where German rules get involved.

Do I need ID to buy a prepaid SIM in Germany?

Yes, and Germany is stricter about it than most of Europe. Since July 2017 every prepaid SIM has to be identity-verified before it will work, so a supermarket starter pack is inert until you complete verification.

You do not need an Anmeldung or a residence permit - a passport and a hotel or rental address are normally accepted. The friction is the verification itself: the Video-Ident systems are built around German and EU documents, and travellers on non-EU passports report failed sessions over document type, glare or camera quality. Some providers let you verify at a Deutsche Post branch instead, which tends to go better. An Ohayu plan needs no verification at all - there is no German number attached to it.

Does the U-Bahn have signal?

Mostly yes now. The operators have equipped the underground network and most lines hold a connection in the tunnels, a change from the dead-zone reputation Berlin had a few years ago. A few older deep stretches still drop between stations.

Troubleshooting

eSIM not working in Berlin?

On an older U-Bahn stretch a short drop between stations is normal. Above ground, check the phone is using the Ohayu line for data with roaming permitted, then toggle Airplane mode once. Chat and support@ohayu.com are open 24/7.
