Swap SIM Card to Different Phone
I already have a prepaid plan and an activated working SIM in my current phone. I ordered a new phone that I'd like to use as my only phone when I receive it.
Can I swap my current functioning SIM to the new phone (yes it is AT&T compatible and an unlocked phone) and just go about using the new phone just fine? Or do I need to update my device info somewhere on the website with the new IMEI also? Or does a new phone need a brand new AT&T Prepaid SIM card that will only be bound to it alone?
