I'm wanting to take advantage of the current offer of saving $10/month on a monthly plan when you migrate over from prepaid. I went into a store yesterday and they sold me a postpaid SIM card and told me to call (which I'm working on). My husband currently has a monthly account under his name. Is it possible to activate this SIM card under his account, port over my pre-paid number, and still take advantage of the credit? It makes more sense for us to have it all under one bill, plus we'd get to take advantage of free family calling. I'm having trouble finding any information about how to follow through with this offer....everything I read says go in to the store, but then the store says to call. Then calling suggests going online.
