Remove cellular carrier from iPad 12.9 2nd Gen
I have an iPad Pro 12.9 2nd Gen. It has no SIM card, and I have done a complete re-set removing all apps and data. Yet Settings > General > About > Carrier still says "AT&T 58.0".
I really don't want to ask AT&T about this, as I've never been a customer and they are known to be unresponsive to issues like this.
Is there any way to really and truly return the iPad to its pristine unlocked status? I'd be very grateful.
