I'm flying into Düsseldorf instead — will it still work?

Yes. This is a national Germany eSIM, so it works at Düsseldorf Airport (DUS) and on the short train hop down to Cologne just the same. One plan covers both cities and everywhere between them.

How much data for a weekend in Cologne?

A compact bundle usually covers a couple of days of maps, tram tickets, translation and social photos of the Dom. Choose a larger allowance if you'll stream music in the brewhouses or hotspot other devices.

Good to know in Cologne

During Cologne Carnival in February, the Altstadt fills with over a million revellers and the mobile networks strain under the crowd — expect slower data around the Dom, and agree a meeting point in advance in case messages lag.

Two simple ways to buy

Cologne eSIM plans: unlimited, or by the GB.

Every Cologne eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Cologne — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Plan your data

How much data do you need in Cologne?

A rough, honest guide to sizing your Cologne eSIM so you're not guessing. Most travellers in Cologne are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Cologne eSIM: your local data guide.

Cologne wraps around its colossal Gothic cathedral, with Kölsch beer poured in Altstadt brewhouses and love locks glinting on the Hohenzollern Bridge. A Cologne eSIM keeps KVB tram times, maps and translation running as you climb the Dom's 533 steps, browse the Belgian Quarter or ride the Rhine promenade by bike.

One eSIM for Cologne and all of Germany. It's the national Germany eSIM — from $2.15/day with unlimited data, working the same in Cologne as it does the moment you leave it.

Landing at Cologne Bonn Airport (CGN)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

On the ground

Where you'll lean on data in Cologne.

Altstadt & the Dom

The cathedral and riverside old town anchor any visit; data covers Dom tower tickets, brewery bookings and quick history look-ups.

Belgian Quarter

Independent shops, bars and street art fill the Belgisches Viertel — lean on maps and reviews to find the best coffee and late-night späti.

Rheinauhafen

The striking Crane Houses and Chocolate Museum line this redeveloped harbour; navigation and photo uploads make the riverside walk easy.

Ehrenfeld

Cologne's creative quarter rewards wandering, with translation for menus and ride-hailing back across town after a late gig.

The practical bit

Getting around Cologne on your eSIM.

Apps you'll want online in Cologne

KVB— Cologne's app for Stadtbahn and bus tickets and live times; also unlocks KVB-Rad bikes.
FREENOW— Germany's leading taxi app; hail a licensed Cologne cab home after Kölsch in the Altstadt.
Bolt— Ride-hailing operating in Cologne; book and track affordable rides across the Rhine, needs a connection.
DB Navigator— Deutsche Bahn app for the short hop to Düsseldorf or Bonn; live times need data.

How long to stay in Cologne

A weekend covers Cologne comfortably, taking in the cathedral, a Kölsch crawl through the Altstadt, the Rhine promenade and the museums, though Carnival visitors often stay longer.

How much data for Cologne

A Cologne weekend of maps, KVB trams, translation and cathedral photos runs comfortably on 3-5GB; around 1GB suits a light overnight, while Unlimited fits streaming Kölsch-bar playlists or hotspotting other devices.

Coverage in Cologne

Cologne has solid 5G across the Altstadt, CGN airport and the tram network, but expect congestion and slower data around the Dom during February Carnival, when over a million revellers share the same masts.

Peace of mind

Your Cologne eSIM: data-only, zero bill shock.

Your Cologne eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Cologne, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
