We're a UK mobile network, so our SIMs are meant for people living in the UK.

You get 5 days of free EU roaming per trip, and any further days abroad will cost £2/day.

This allowance resets every time you get back to the UK, so you won't pay a penny for those weekend getaways or midweek business trips.

You can use your normal allowance when roaming (up to 20GB per month on our Unlimited plan).

Please note that calls to EU numbers are not included in this and if you spend over 60 consecutive days in the EU, Three reserves the right to ask you to transfer out or pay extra to continue to use your SIM. We'll always give you notice if Three request this.
