Hi, I am a mum from Australia, my daughgter has started College in Tishomingo Oklahoma 74360 and needs a USA Mobile. The T Mobile site shows that they have coverage in her area....but....when you try to go to the T Mobile plans online it says that they do not have a service for 73460. What the???? If I put in the Zip Code for Madill a few miles away that works and I can see the Individual Plans etc....can I still order her a phone?, will it work in Tishomingo????? AT&T require 2 year contracts and are expensive especially as she will be calling Australia from time to time...any advice would be greatly appreciated.
