Questions UK travellers ask

Which UK network has the cheapest roaming?

It depends on your plan and destination. O2, Three and Vodafone publish daily charges or passes; EE prices vary by destination. For trips of a week or more a travel eSIM is often cheaper than any daily charge.

Do UK networks still include roaming in Europe?

Some plans include Europe roaming, others charge a daily fee. Check your own plan before you travel.
