Going abroad? 


International Roaming Guide for Vodafone and O2 networks

Before you leave the UK and travel abroad, it is important to think about what you'll need your device for.  Will you need to look at email or the internet?  Will you need to make and receive calls or even access your voicemail?

If you need email and other data services, we can help advise on which networks you should try and roam on to once abroad, as some networks only support voice.

Please try and let us know if you're travelling.  Its useful to know where you are going and for how long as we can advise on any bolt on's which might help you keep your costs down.

If you are going to need to access your voice mail, you will need to set it up prior to leaving the UK.
