charges on bill

[whyamisofab]

There are charges for making calls while oversees, my phone was not able to make or receive calls while in USA so how can I have made these calls, also the number called is my own !

Did you turn Voicemail off before you travelled @whyamisofab?

If you check your billing in My O2 you should have a breakdown of charges.

If you need to contact O2, all ways are in this guide Guide: How to find help & contact O2
