Factory rest of unlocked T-mobile

[goober84]

I have a Galaxy S6 (T-Mobile) that has been unlocked from T-mobile and I am now using on At&t. My question is if I factory reset it will that undo my unlock from T-mobile? Thanks for the help!

IT shouldnt. The unlocking should be done on the core level and by hard resetting your device back to factory should leave the unlocking alone.

Thanks for the response. I'm just preparing for if I have to do so for some reason in the future haha.
