I also forgot to ask this in the OP. So the precise details of my trip is this, I'll be spending 8 days in total split between Boston and New York City. Then, starting from November 30th, I'll be spending 5 weeks in the US split between Hawaii, Los Angeles, and Boston. If I get a T-Mobile or AT&T sim card, can I pause or suspend my account after my 8 day trip and resume when I fly back to the US on November 30th?

Thank you!
