iPhone 11 has 2 model #'s
My IPhone 11 has 2 model numbers. AT&T-A2111, and Verizon MWAV3LL:A which is a gold IPhone 11 Pro. How can this be? I have dual SIM card but I never used the second line anywhere.
Every iPhone has. Whether Dual SIM or Single SIM
A2111 is the Model Number
MWAV3LL/A is to identify the country where it is originally sold. (In your case it is "LL" hence USA/Canada
