Re-use SIM card for prepaid
I visited the U.S.A for short-term bussiness trip last week and bought prepaid SIM card at AT&T store to use my smartphone.
And my account will close because my account isn't set AutoPay.
If I visit the U.S.A again, can I use same SIM card without visiting AT&T store ?
My expectation is that I can set a prepaid plan and activate the phone by using internet.
