SPRING/ MVNO T-MOBILE IPHONE XS SIM LOCK PROBLEM (ON UPGRADE IOS17)
Hello; I purchased a SIM-unlocked phone in 2018, and I have been using my phone without any issues for years. When I upgraded to iOS 17, my phone entered restore mode, and when it was reset to fact...
Then it sounds like you are a victim of Apple's reseller policy, where the first SIM put in the device, the device SIM locks to. If that SIM isn't recognized, then the device will sometimes not lock to that specific provider. Again, updates and factory resets do not alter the SIM lock/unlock state on the device!
If you purchased the device new and were a Sprint customer and used that device on the Sprint network long enough to meet all of the SIM Unlock Policy requirements. Then you can send a copy of your receipt with your account number that you purchased the device on and reach out to Customer Care or send a DM to T-Mobile on Facebook or Twitter to verify those requirements are met. Once all of those requirements are verified as met. Then T-Mobile can request the device be SIM Unlocked from Apple, which can take 3 weeks or longer.
