Frequently Asked Questions

Is an eSIM needed for the UK?

For non-EU visitors, yes. International roaming in the UK is expensive, and a local eSIM plan is significantly cheaper. EU residents who previously enjoyed free EU roaming no longer have that right in the UK after Brexit.

Does eSIM work across the whole UK?

Major networks (EE, Vodafone, Three, O2) cover most urban and suburban areas well. The Scottish Highlands, remote Lake District, and rural Northern Ireland have patchier 4G. Most tourist attractions and transport links are well covered.

What is the best eSIM plan for visiting London?

A 5–7 day plan with 3–5 GB is sufficient for most London visits. If you are travelling beyond London to Edinburgh or Manchester, a 10–15 day plan with more data accommodates navigation and transport apps across longer distances.
