Is iTunes required to unlock t-mobile devices?
My 11pro has been unlocked in t-mobile and received an email from the technical team. I waited for 24 hours and then inserted other mobile phone cards, but it showed that the mobile phone card did not support it. I asked the customer service representative and they said that the device had been unlocked. Let me use iTunes to restore him, but I am not sure if this is useful.
iPhone 11 Pro, iOS 14
