iPhone 7 does not recognize any SIM or Carrier

Hey all, Just a general question.

So I have a nice iPhone 7 128GB that came across my desk that wont recognize any of the SIM cards I put in it. All SIM cards are confirmed working on their separate carriers. Now, I put a VERIZON card in it and the phone recognized the service, but came up with a "Network not Recognized" error. So I'm kinda stuck. Any help?

I was thinking this could be a China bought iPhone?

See if any of the SIM cards pins bent, also you can just look up the model number to see what carrier it is.

I'll check out the pins. I did search the Model number only to come up with "Verizon/Sprint/China" (Thats coming from Everymac,com) Again, that leads me to believe that the phone is of Chinese origin.


@bennythejet what is the model number?


a1660 / mn8p2ll/a


@bennythejet Try a China Mobile SIM card, see if that works.


We got it figured out. Though the model number classifies it as a CDMA, it recognized a T-Mobile SIM.
