Cheapest Way to Use Phone while in the USA
I've recently purchased a Galaxy S2 on contract with O2. I expect to have the phone in the next couple of days and understand that it will be unlocked.
I will shortly be on holiday in the USA. What will be the cheapest way to use the phone whilst I am over there? I will want to access the internet, send and receive texts to other people in the States, call and receive calls from other people in the States, and receive texts from people in the UK. I may want also want to send texts and make and receive calls to people back home in the UK, but this is less likely.
Thanks in advance of your help!
