Telecom🇩🇪 Dortmund, Germany

Getting a German SIM, and a network that saturates on matchdays

Germany requires identity verification for every SIM including prepaid — passport or ID, verified in a shop, by video call or at a post office. Prepaid needs no Anmeldung or Schufa. Postpaid contracts run a Schufa check a newcomer will fail or pass marginally, so start prepaid and switch once you have a record. Coverage across the city is good; the one predictable failure is 81,365 people in one place on a Saturday afternoon.

Total cost
Prepaid plans with reasonable data allowances are inexpensive by western European standards. Postpaid costs more but usually includes more data. Home broadband is competitively priced; the cost is in the waiting.
Time needed
A prepaid SIM works within minutes of verification. Home internet takes weeks.
Validity
Prepaid renews monthly. Postpaid runs a minimum term of at most 24 months, after which §56 TKG allows cancellation with one month's notice.

Medium confidence·Anyone living in Dortmund. German telecoms rules are federal: every SIM must be registered to an identified person, and prepaid activation requires identity verification.

Before you start

  • Passport or national ID for verification
  • A German address, for postpaid contracts
  • A German bank account, for postpaid direct debit

Step-by-step

  1. 1

    Buy a prepaid SIM and verify your identity

    Available from supermarkets, phone shops and online. Activation requires identity verification — in shop with your passport, by video call, or through the Post's identification service.

    Do not attempt a postpaid contract in your first weeks

    Contracts run a Schufa check and require a German bank account and registered address. With no credit history you will be declined or asked for a deposit.

    Order home internet the day you sign the lease

    German broadband provisioning routinely takes several weeks and can require an engineer visit. Ordering on move-in day means a month of tethering.

    Agree a meeting point before a match

    Tens of thousands of people in a few streets saturate the mobile network around the stadium and the Hauptbahnhof on matchdays. Calls fail and messages arrive late. Fix a meeting point and a time in advance, which is what locals do.

    Check what is physically in the building

    Fibre has reached much of the centre, Hörde and the newer developments; large parts of the older housing stock are still on copper. A provider's postcode checker will sell you a speed the line cannot deliver — ask the landlord or the previous tenant what they actually got.

    Know the cancellation rules

    Since 1 December 2021, when the reformed Telekommunikationsgesetz took effect, a telecoms contract continuing past its minimum term can be cancelled at any point with one month's notice rather than auto-renewing for a full year. Check your specific terms — older contracts may still run on the old basis.

Documents you’ll need

  • Passport or national ID for SIM registration
  • Meldebescheinigung, for postpaid contracts
  • German bank details, for direct debit
  • Schufa report, which some providers request

Things most newcomers don’t know

The network gives up around the stadium on a matchday.

Eighty thousand people in a few hundred metres saturate every operator's cells, and the Hauptbahnhof afterwards is no better. Messages arrive an hour late and calls simply fail. Locals fix a meeting point in advance; newcomers rely on their phones and spend the evening looking for their friends.

Even prepaid SIMs require identity verification in Germany.

Every SIM must be registered to an identified person, so a supermarket prepaid card still needs a passport check. Arriving expecting to buy an anonymous SIM off a shelf wastes an afternoon of your first week.

Home internet takes weeks, so order at lease signing.

German broadband provisioning routinely takes several weeks and can require an engineer visit. Order the day the lease is signed, using the future address.

The reformed telecoms law fixed a real contract trap, and it dates from 1 December 2021.

German telecom contracts historically rolled over for another full year if you missed the cancellation window. Since the Telekommunikationsmodernisierungsgesetz took effect on 1 December 2021, §56 TKG caps the initial term at 24 months and lets you cancel at any time with one month's notice thereafter.

Common mistakes to avoid

  • Relying on your phone to find people on a matchday.
  • Expecting to buy an unregistered prepaid SIM off a shelf.
  • Applying for postpaid before you have any Schufa record.
  • Ordering home internet on move-in day rather than at lease signing.
  • Believing a postcode checker over what is physically in the building.
