These phones when purchased through Best Buy will lock to the first SIM card inserted. Do not go back to Best Buy and ask them to unlock the phone as they are not able to unlock iPhones. They have limited access to unlocking services and will refer you to T-Mobile. Follow these steps to unlock your iPhone.
Steps To Unlock Your iPhone (T-Mobile ONLY)
1) Call T-Mobile customer service or message them through the T-Mobile app and let them know that you would like the phone unlocked. They should be able to unlock the phone after you provide them with the IMEI number.
2) If T-Mobile gives you the runaround and tells you that they can't unlock your phone because it was not sold by them but by Best Buy, contact Apple Support. DO NOT GO THROUGH BEST BUY. Let Apple know that you reached out to T-Mobile but they don't want to unlock the phone because it was not sold by them. Ask Apple to reach out to T-Mobile while you are on the line with them. Apple should be able to get in touch with T-Mobile. At that point you'll be on a 3 way phone call. Explain to T-Mobile your situation and tell them that you want to get your phone unlocked. They're going to tell you that they'll be reaching out to their "Back Office" to unlock the phone. After that, you should be fine. It may take a few hours from contacting the Back Office for them to unlock the phone.
