How to avoid Three roaming charges

  1. Before you fly, install a travel eSIM at home on Wi-Fi.
  2. On landing, set mobile data to the eSIM and turn on data roaming for the eSIM only.
  3. Turn data roaming off for your Three SIM so you aren’t charged a daily fee for background data. You can still receive calls and texts.

Questions UK travellers ask

How much does Three charge for roaming?

Three daily roaming charge: £8 a day if you joined or upgraded on or after 18 December 2025 (£7 for customers who joined between October 2021 and December 2025), in Three’s Go Roam destinations. It lets you use your UK allowance abroad, up to 12 GB.

Is a travel eSIM cheaper than Three roaming?

For trips of a week or more it often is, because a daily charge adds up every day you use your phone. Compare the chart above for your destination. If your Three plan already includes your destination at no extra cost, use your plan.

Can I keep my Three number while using an eSIM?

Yes. Keep your Three SIM in your phone for calls and texts, turn data roaming off for it, and use the eSIM for data.
