What should I do?
I will go to the U.S this summer and spend the whole summer as a summer college student. And then I'll go back to China, then after a year, I will go to the U.S to study for more than three years. And I want to use AT&T's network this summer and later after I get to the U.S university. I have two questions
1. I already have an iPhone that supports AT&T's network bought from the Apple Store, so can I just set up a number?
2. Can I use the same account and number I used during my summer time when I get to U.S university next year?
