A 5110. (With the Snake game, IIRC.)
My first phone was a MicroTAC - a huge Motorola thing (about 25 years ago). Still have 2 of them out in the shop, and they'd still work if there was an analog cellphone network.
I had a Bag Phone at around the same time. (That was a phone in a small bag, like an overnight bag.)
Before that I had MTS (that's going back to about 1970) and IMTS phones (you could dial calls instead of yelling for the operator) in my car.
