My burner is a TracFone with prepaid minutes. I got it when they had a 2x promo, so now every time I reload it with minutes, I get double, eg. when I add 120 minutes, I get 240. The phone itself is very basic. The kind where you have to press the number more than once to get the right letter when you're texting. Cheap and compact but no frills on other smartphone functions. No monthly fee. It has "service days"
