I switched to Tello right when RingPlus was going out of business a few years back. I like it.
It's super cheap for me. I am using a phone that is 2 1/2 years old that I bought for $20 during a Black Friday sale, and I don't have a Tello plan, so I use Pay as you go. I use less than $1 of service per month, so I don't even bother putting it in my budget. I hate talking on the phone and am usually on wifi at home and work, so my cellular data usage is almost non-existent.
