What is the next step with my “unlocked” iPad?
Hi. So I bought what I thought was an iPad pro locked to AT&T at a pawn shop. I went to the AT&T website to unlock it, and it turns out it was already unlocked. I am currently with Sprint, and I would like to add the iPad as one of my lines. I put in my iPhone’s Sprint SIM to test it out. The cellular data works, but I still get the “the sim card has locked please power cycle” error every few minutes. I’ve turned the iPad off and on, and this still happens. Does this mean my iPad is not unlocked? If my iPad is unlocked, like i think it is, how should I go about adding my iPad to my list of devices on my Sprint plan?
