How does T mobile will know, which phone belongs to which line/contract for getoutofred reimbursement ?

    Me and my wife ( 2 lines total ) switched to T mobile last week from Verizon. 

     

    Final bill from Verizon doesn't show phone models ( like Iphone 7 Plus ). Not sure while submitting reimbursement claim for getoutofred, this will be an issue. I do not want to get rejected for reimbursement claim even if I have qualifying phones.

     

    I am sure I am not the only person where Verizon did not put phone model on final bill.   What I am wondering here out of curiosity is - how does T mobile knows, which phone belongs to which line/contract  when Verizon bill doesn't mention anything about model number ?
