I bought my S21 in June of this year off of Samsung's website. I selected the carrier T-Mobile instead of unlocked because I was under it at the time. I recently (today on Oct 23) switched my carrier to AT&T, but when I put the AT&T SIM card in, my phone wouldn't accept it. I tried to go to the Network Unlock settings and pressed the permanent unlock, but it told me "Your phone isn't eligible to be unlocked: reason code 132".
I called T-Mobile, who told me that they were unable to unlock it and that I needed to contact Samsung instead. I called Samsung, who told me that my phone was locked by T-Mobile and only they could unlock it. I ended up physically going to a T-Mobile store, and the worker called tech support in T-Mobile. They said that since I technically bought it off Samsung, T-Mobile wasn't the manufacturer and they were unable to use my IMEI to unlock my phone.
I have been calling back and forth between the two for a couple of hours now and I still haven't gotten it fixed. I messaged both T-Mobile and Samsung on Twitter and have not yet gotten a reply. I saw that this seemed to be an issue for some people but there has never been a clear solution. Please help me.
