Travel & roaming without bill shock
Since the UK left the EU every network writes its own roaming rules. Five minutes of preparation beats every horror story.
Before you travel: the five-minute drill
In the official app — destination, daily cost, what's included. Plan generation decides everything; folklore decides nothing.
Exceeding it triggers per-GB charges even on unlimited UK plans.
Every network offers one; it's the difference between a surprise and a shrug.
A local data profile beside your UK line often beats daily fees by a mile — eSIM guide.
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.
