Switching my Samsung Galaxy S20 from ATT to T-Mobile but nothing was explained properly by the many staff I spoke with at both carriers. As a result I entered an incorrect "unlock code" too many times and now can only use the "MCK" code to unlock it. Everyone says to call everyone else and I have worked on this issue for over 8 hours today but still don't have a phone to use despite now paying for a plan with ATT & T-Mobile. Do I really need to go to a Samsung approved store to pay to get this unlocked? This has been shear insanity. Thanks in advance to anyone who can help.

You would need to get the MCK code from AT&T since they were your original provider it might take a little bit ask for a supervisor

@userO4Dz76EyiW If it was originally an AT&T locked phone, then AT&T would be the only one who can unlock it.
