I updated my phone last night sometime and since the update it's told me that my SIM card is Network locked and that my device is Network locked I guess and it's asking me for the MCK(Master Unlock Code).

I contacted both Spectrum & Samsung & they are both telling me that I have to contact the other to fix the problem

Have you tried taking out your SIM card, reset network settings, this will erase all settings, network, wifi passwords, Bluetooth devices. Put SIM back in phone

You might have to go to your carrier and get a new SIM card

For those seeking the most recent update on this matter, I find the outcome quite amusing. Despite Spectrum providing substantial evidence to AT&T, they persist in asserting ownership of the device. Consequently, Spectrum has decided to replace the device, but the question of how AT&T obtained my device information remains.
