Network & Coverage

Stay connected across every corner of Cologne

Your eSIM connects to O2 and Vodafone — both with 5G — across Cologne and on through Germany. The phone takes whichever network is strongest where you stand.

5G coverage across Cologne and on through Germany.

Where you will use it

the cathedral and AltstadtEhrenfeld and the Belgian quarterDeutz across the riverthe trains along the Rhine

During carnival large parts of Cologne are closed to traffic for several days and the transit network reroutes daily — the app knows, the timetable on the wall does not.

Does the Cologne eSIM work outside the city?+

Yes — it is a Germany-wide plan. This page exists because people search for the city, not the country.

Can I share it as a hotspot in Cologne?+

Yes. Tethering is allowed, which is what makes one unlimited line practical for a couple or a family moving around together.

How it works

Connected in
3 simple steps

Before you fly

Scan the QR code over Wi-Fi. About a minute.

On landing at CGN / DUS

Turn off flight mode — the line registers by itself.

Turn on data roaming

The step most travellers miss. It is not roaming in the billing sense; it is how the phone lets the eSIM use a foreign network.

✈️

Ready before you land

The train from Köln/Bonn straight into the Hauptbahnhof beside the cathedral — and your eSIM is already working when you get there.

Frequently asked questions

Everything you need to know about your Cologne eSIM

Is the data truly unlimited?+

There is a fair use policy, as with every unlimited plan on the market. We publish the details on our fair use page rather than bury them, so you can check before you buy.

When does my Cologne eSIM activate?+

On its first connection to a local network — in practice when you switch off flight mode at CGN / DUS. Not when you pay.

Can I buy it weeks before the trip?+

Yes. It stays dormant until it first connects, so buying it together with the flight is fine.

Should I buy a SIM card at the airport instead?+

You can, but it means queueing after a flight and paying whatever the counter asks. An eSIM bought beforehand is already working before you reach passport control.

Which devices are compatible?+

Any eSIM-capable handset — iPhone XS and newer, recent Samsung Galaxy, Pixel 3 and newer. Dial *#06# — if an EID number appears, you are good to go.

Can I extend it if I stay longer?+

We do not extend a plan that is already running. For more days, buy another eSIM for the same destination — it arrives by email and installs alongside the one you already have.

Only staying a few days?

A short trip is usually cheaper on a fixed data plan — same networks, one price for the trip.
