I was able to purchase an iPhone 8 through my company with AT&T being the carrier. I have since left the company and would like to use the phone with a T-Mobile plan. When I put the T-Mobile SIM card in I receive the message Not Unlocked for that Network. Any suggestions on how to make this work or can I use the phone w/AT&T only?

Best Answer
Your original provider Controls the network lock status.
Procedures differ per other providers, but for you, start at AT&T to check your lock status or request it be changed.
