Thank you for the quick reply, my current phone i bought it at an o2 shop and got a sim only deal but they don't do that now and i didn't want to pay monthly, and now i know i can buy one from elsewhere, many thanks again.
Yes, thats what I do. Bear in mind certain functions may not be available ie 4G calling and Wifi-Calling to a non-o2 handset you intend to bring across as in some cases they need the O2 Firmware to be present on the new phone.
