New to all of this. I used to jailbreak, unlock iPhones but am unfamiliar with this side of things. I was able to remove the passcode and Google account off the Pixel 6a which was on A13 and updated to the most recent patch (Let me know if you need instructions as that was not easy for me to find). But now I found that it is locked to AT&T which I do not have. Is it possible?
