So I went to Sprint to get a phone I know not the best place to go but they had a great deal on the new essential phone only 150 to pay it off after 2 months.

To my surprise I had gotten a mail that said my credit score check was 739 how is this possible I had only done a few things to even get credit and I'm not sure if they did. I've gotten a the from rent a center and had a contract with at&t when I was 17 but I'm only 20 and done nothing to get good credit explanations anyone?
