Visiting London or Manchester from Poland is exciting — don't let data limits spoil it.

Whether you're landing in London Heathrow, visiting family in Manchester, or exploring Edinburgh, you need reliable data. Post-Brexit roaming policies can be confusing and restrictive.

That’s why Polish travelers choose a UK travel eSIM — installed before departure and ready the moment you land.

Why Roaming from Poland Can Be Tricky

The Problems:

Post-Brexit Rules: While some PL carriers still offer free roaming, Fair Usage Policies (FUP) often limit GBs.

Speed Throttling: Roaming data can be slower than a local connection due to network deprioritization.

Data Limits: Your domestic unlimited plan might have a small cap (e.g., 3GB) in the UK.

Common Questions

Frequently asked by our Polish customers

It depends. Since Brexit, UK is not always in Zone 1 (EU). Even if included, FUP limits often apply (e.g., only 1-3 GB of your plan is usable). Cellesim gives you a dedicated high-speed allowance.

Yes. You can keep your Polish SIM card active for calls and SMS (crucial for BLIK and bank codes). WhatsApp will continue to use your Polish number while using Cellesim data.

No. Unlike buying a physical SIM card at a shop in some countries, Cellesim eSIMs are hassle-free. Just scan and go.

We recommend installing the eSIM at home in Poland (while you have WiFi). The data plan will not start until you actually connect to a network in the UK. So you lose no days by installing early.
