The first rep I spoke to was obviously NEW and knew nothing about activating my iPhone 5 on a differnt number on my account than the number that was upgraded. Now I get mixed answers most of them saying I can't activate on a differnt line until the sim ages out in about 24 hours if you are going through this or if you have got your activated on the line you want after the 24 hours please explain! My last rep I spoke to NOW says the sim card needs to be removed for 24 hours.... I have no idea what's going on or if I will be able to activate this on another line!
