International
When you make calls and texts, while in the UK, to someone who is not in the UK

Roaming
When you use your phone (calls, texts or data) while not in the UK

It is always advisable to call in to customer services prior to travelling, just to ensure there are no bars on your account

All incoming calls are free whilst you are in the UK

Typically, you’d be billed on your next invoice, however, it can take up to 3 months to be billed for any international or roaming charges

Usually your handset will select a network automatically, however, this isn’t always the case. If you are getting no service, try manually selecting a network in your device settings

If the above doesn’t work, you will need to contact customer services
