Will receive NCK+ PUK /Defreeeze (MCK or PCK) codes.
This works for Galaxy S21 G991u S21+ G996u S21 Ultra G998u from any Usa network that asks for code,basically AT&T Xfinity Spectrum.
There is no refund if we deliver the code but you can not use it because the phone is not asking for unlock code with a sim from a different carrier!
-First, try the Network code when the phone asks for unlock code with a different SIM, and if not working or it asks for PUK CODE, factory reset it, insert the Defreeze code (even if seems that is not accepting it, is OK) and after use the Nck code and should work.
NO REFUND IF PHONE HARDLOCK OR CODE NOT WORK
ADD IMEI ON YOUR RISK
