What cell phone company only pulls your credit score from transunion?

i know for a fact t mobil does? they only pull transunion, they just lowered their credit standards so you can get approved with a lower score than before, and one way or another youll get approved with them, either a post paid account witch means they bill you monthly its not pre paid, or they will give you an account where you pay in advance but its not like a pre paid you get a plan the same plan youd have if they billed you monthly you just pay at the start of the month, and they report your payment history to the majore credit bureas each month so it helps you to build and re establish credit, so they can get you a plan one way or another and you wont waste an inquiry on your credit, and they have exspanded coverage and they cover most areas just as well as Verizon these days hope this helps.
