Users who activate Apple’s own SIM card to use an AT&T data plan with the Wi-Fi + Cellular models of iPad Air 2 or iPad mini 3 are finding the SIM will lock itself to AT&T, and can no longer be used by another network. Though it appeared the SIM card would be interchangeable between AT&T, Sprint, and T-Mobile — though not Verizon — it’s not the case with AT&T.
The issue was confirmed by Re/code through AT&T spokesman Mark Siegel, who said users will need another SIM card to switch carriers, as the device remains unlocked. Why did AT&T decide to lock its card, unlike T-Mobile or Sprint? Siegel said “it’s just simply the way we’ve chosen to do it.” An Apple support document notes: “If your Apple SIM becomes dedicated to a specific network and you want to choose from other carrier programs, you can purchase a new Apple SIM from an Apple Retail store.” T-Mobile CEO John Legere tweeted a screenshot of AT&T’s SIM card prompt on Thursday.
