Activate new service (1-year pre-paid), port another number, already have SIM
I wish to activate a new 1-year pre-paid service and port our AT&T home landline number to it. The store gave me a SIM and said I need to do this online for the $300 1-year offer.
--The store gave me a SIM, but the offer page automatically applies a new SIM charge. Do I need to order a SIM?
--How do I port the other number to this device? The store said this is possible to do.
