Hello, I saw at https://z3x-team.com/check-your-phone/ says Unlock SPR using credits and Unlock using credits, I'd like to know what carriers unlock that second option (Unlock using credits) and doest it work for tmobile G975USQS2ASF7?
Hello, unfortunately, G975USQS2ASF7 from T-Mobile is not supported at this moment.
If there is no option:
Unlock TMB using credits
then it' s not supported.
