Just a few days ago I got an iPad Air 2 via Verizon. On the account, there is a phone number associated with the line for the tablet. Is that number functional? I guess what I mean is, can you answer phone calls or make calls with the number associated with the tablet? I've tried calling the number from a different number and nothing happens, but I'm not sure if it's just me.
If it is supposed to be a functional number then is there a way for me to add that number to an already existing Apple ID that is associated with my iPhone phone number?
