I lost my SIM card for my post paid account. I see a new SIM card will cost me $25 fee and this single mom doesn't want to spend it. My question is this, can I purchase a prepaid SIM card (unactivated), put it in my unlocked phone and have t-mobile customer service (611, or online) activate the prepaid SIM for my postpaid phone number and current plan?
Hey, magenta4993112! I'm so sorry to hear about the lost SIM -- usually that goes hand in hand with a lost device, and that's a horrible situation to be in! The starting balance on a Pay in Advance SIM doesn't transfer to a postpaid account, so your best bet when you need to Buy or change SIM cards is to purchase one that works for your particular account type.
