Switched to Visible just over 3 months ago from ATT (had been on ATT since 1993 with bag phone)...
4 of us joined about same time so $25/month from after first month. Got the $20 promo so first month was only $20, then after a couple months got the $100 Mastercard. So Moto G Power phone that cost $180 wasn't so bad.
Works pretty well.. calls over WiFi are not very good from our house, we often turn off wifi on phone to get better call quality. I've used it as hotspot and streamed movies okay.
Our cell reception is -108db so not that great... I try and do speed tests when we're out and about to see how it is other places.. hoping we get decent coverage camping this summer, but no worries if we don't.
I would rate it a good value.
