Hi, i want to add bitcoin adress… Yeah gameflip asks me for paperwork i already provided, photos id etc… but they also want my mobile numer with a photo of it’s invoice/bill. How i can get that if the number is prepaid or on another name? 
Hello!
Did you tried to call your sim card’s company? If not, tell them to get you a bill showing your full name and your address, Then you can simply give it to gameflip and they will approve it for sure.

You didn’t understand 
sim cards can be bought anywhere.
