My wife currently has an iPhone 6 and recently received her mom's iPhone 7. I erased and reset the 7 for her and when I put the sim card from the 6 into the 7 everything comes up from the 6 but there is no connection to T-Mobile. In other words, the phone number from the 6 did not transfer to the 7. Any suggestions?
Is the iPhone7 unlocked?
I think it generally throws an "invalid SIM" message, but your phone number is tied to the SIM card. If the SIM card is in the phone, if the phone isn't locked to another carrier, it should work. If it's locked to another carrier, you should get an error message.
