I've installed Apple music and when I try to verify it says I don't have an we account with Apple music. After looking around about this I think it may be because when I moved to EE I changed the number to my previous number, and if I go to the phone number in the phone settings (s8) it is not my number but in fact the number of the sun initially. I think Apple may be looking at this number on the device and not in fact the actual phone number. I don't think this number can be changed either? Any ideas?
