iPHONE IMEI NOT RECOGNIZED trying to activate my iPhone BYOD
I have an iPhone that I am trying to activate to use with my current my Virgin Mobile account. It is an iPhone 6 Plus model a1522 and was originally an AT&T phone.
before I had this phone sent to me, I checked with Virgin Mobile customer service that I could use the phone. Once I received the phone, I installed the SIM card sent to me by Virgin Mobile and set up the iPhone.
AT&T has verified they unlocked the phone, I finished the unlock through iTunes and received the message "Success! Your iPhone has been unlocked"
After getting this message I called to get it activated to my Virgin Mobile account only to be told that my IMEI number is not compatible. I am totally confused. Please help!
