4 phones on my fam plan. Phone A is a 3Gs, B - 3Gs, C - dumb, D - dumb. The dumb ones are upgrade eligible. Can I order an upgrade to the iP4 for one of the dumb lines, call (or visit) AT&T and provide them the number on the sim cards from the new iP4 and the sim on the dumb one and get them to switch the phone numbers back?
Sorry if that's confusing. I provide my dad with a cell. He using an older Nokia and doesn't need to / want to upgrade. I was going to order the iP4 on that line. When it comes to me I want to replace my 3Gs with it and he'll continue to use the Nokia. He doesn't have txt, data or anything on his so I'm thinking there could be a snag with the services but I wasn't sure.
When you purchase a "smart" phone, are you committing to a service (data and/or text) to be eligible for the promo price?
