UK Roaming Charges Explained in 2026
Travelling abroad from the UK? Roaming policies have changed significantly in recent years. This guide compares EE, O2, Vodafone, Three, Tesco Mobile, giffgaff and Lebara roaming policies, explains fair usage limits and helps you understand whether roaming or a travel eSIM makes more sense.
What happened to EU roaming after Brexit?
Before Brexit, many UK travellers benefited from "Roam Like at Home" rules across Europe. Today, UK mobile operators set their own roaming policies. Some networks still include roaming in selected plans, while others charge daily fees or require travel passes.

Why roaming bills still surprise travellers
Many travellers assume their old roaming benefits still apply. In reality, roaming costs can depend on the destination, your tariff, fair usage limits and when your contract started.
Check before you fly
Before travelling, check whether your destination is included in your roaming allowance and whether any daily charges or fair usage limits apply.
