My iPhone says model MQ3U3LL/A then A2632

on apple that shows up as an iPad model and mentions a part number

i don’t have or use and iPad for my phone or accounts

we purchased our phone brand new from our cell phone carrier in the store. We have not had any work done on our phones

We have had identity fraud

problems with several types of accounts, including mobile phone accounts

Is someone able to control my iPhone/phone number somehow from an iPad with cellular service? And my AppleID?

it doesn’t matter what I change my password too, my accounts keep getting hacked and changed by someone else.

How do you stop identity theives?
