Please read first Kestrel Hub is an independent third-party information centre. We have no affiliation with, authorisation from, or connection to any network mentioned on this page — trade marks belong to their owners and appear only to identify subjects. We sell nothing, cannot open or change any account, and never take payments or security details. Billing, contract and account matters belong with your network's official customer service. Our helpline gives general information only, at standard geographic call rates.

Before you travel: the five-minute drill

Read your plan's roaming page

In the official app — destination, daily cost, what's included. Plan generation decides everything; folklore decides nothing.

Find the fair-use cap abroad

Exceeding it triggers per-GB charges even on unlimited UK plans.

Set the free spend cap

Every network offers one; it's the difference between a surprise and a shrug.

Long trip? Price a travel eSIM

A local data profile beside your UK line often beats daily fees by a mile — eSIM guide.

Kill data roaming when idle near borders and at sea

Maritime and satellite networks charge premium rates and connect uninvited.

Where the four networks broadly stand

Which UK network still includes EU roaming?

O2 has been the hold-out keeping inclusive EU roaming on standard plans (fair-use cap attached). Three and EE generally charge daily fees on newer plans — some higher EE tiers bundle a travel pass back in — and Sky Mobile runs daily passes. Every clause is generation-dependent; your app has your answer.

A roaming bill looks wrong — can I challenge it?

Yes. Worldwide data-roaming financial caps must apply unless you actively opted out; charges past caps you never lifted are challengeable. Keep evidence and climb the ladder in the complaints guide.

Want to talk it through?

Our helpline answers general questions about anything in this hub — switching, coverage, complaints, staying safe. We can't open accounts, take payments, or act for any network.
