Woman using smartphone

Patty's daughter is going to spend a year in Great Britain. How can she bring along her cell phone? Leo says she could run into serious data roaming charges, so he recommends just getting a local SIM and number. She could check out prepaidwithdata.wikia.com. She may have to get her phone unlocked to do it, but it will work. Some companies like Sprint have a "world plan" but if she adopts it, she may lose the current plan she has. Better yet, she should just get a phone in England because that way she'll know the radios will work. She'll have an English number, but that's OK.
