I paid off my iPhone 6s on T-Mobile last month and just requested to have my iPhone unlocked...I'm moving to Verizon on Sunday and T-Mobile sent me an email with the following instructions to unlock my iPhone. "Thank you for taking the time to contact T-Mobile. 24 hours after receiving this email, follow the below instructions for unlocking your T-Mobile iPhone. If you have a non-T-Mobile SIM card, follow these steps: If you have a non-T-Mobile SIM card: 1. Insert non T-Mobile SIM Card 2. Complete the setup process. If you will be using your T-Mobile SIM card follow the steps below: 1. Back up your iPhone using iTunes. 2. When you have a backup, erase your iPhone. 3. When you see the Welcome screen, connect your device to iTunes. If successfully unlocked, the message Congratulations, your iPhone has been unlocked will display. Additional information for unlocking Apple iPhone devices can be located at https://support.apple.com/en-us/HT201328" I don't have a new Sim Card yet since I'm switching on Sunday but I followed the bolded steps above and I never got the "Congratulations, your iPhone has been unlocked" message that it mentions. Can anyone who's gone through this explain in better detail how to unlock (or confirm) my iPhone has been unlocked? Thanks!
