Can you reccommend an unbelievably simplistic cell phone for mom (pay as you go)

[hal]

My mom HATES cell phones, but needs one. She DOES NOT want an iphone nor any substitutes. She wants something that is as basic as possible - something that makes phone calls - absolutely no other features required NOR desired.

Used to be lots of tmobile deals (no contract, pay as you go with refill cards) with really, really simple phones... did those dry up?

Any reccs?
