Looking for a dumb phone for a college student

I’m planning to go into college soon so money isn’t something I’m exactly swimming in, I want to find a dumb phone that’s preferably a candy-bar form, I don’t really care about features, I just want call, text and contacts storage. The less money I need to spend the better. I currently use Verizon put im planning to switch to AT&T. I also have a spare SIM card and number from Tello but I’m unsure of wether these kinds of phones will work with it. Any help would be a great help!
