International roaming and overseas calls aren’t possible with any of the SMARTY plans right now, although you're still able to receive calls from abroad when you're in the UK.

In the meantime, if you’re going abroad and you'd like to keep in touch with family and friends, you've still got plenty of options. Hook up to any available WiFi signal and use apps like WhatsApp.

You can also use these types of apps to keep in touch with anyone else who is travelling overseas.
