Frequently asked questions
How do I activate Go Roam?
Go Roam works automatically when you arrive in a Go Roam destination as long as data roaming is switched on in your device's settings. If you’re a Pay As You Go customer, you’ll need to have activated your SIM and made a chargeable event such as making a call, sending a text or getting online, in the UK first. When you arrive in your destination, you’ll receive a text confirming the roaming costs in that country. To check out the standard international roaming charges for the country you’re visiting, go to Roaming Charges and choose your destination.
Don't forget that when you're calling or texting back to the UK, you'll need to replace the first 0 in the number you're calling or texting with +44.
What else do I need to know about Go Roam?

With Go Roam in Europe you can use your allowances to call and text back to the UK and use your data, (up to our fair use limit) as well as make calls and send texts between our Go Roam in Europe destinations, and it won't cost you a penny more - fair use policy applies. If you don't have any allowance left, you'll also benefit from competitive roaming rates.
