I've been using Total Wireless, which is one of TracFone's subsidiaries and an MVNO for 2+ years, and they are fantastic. For $35 a month I get unlimited talk and text, 5 GB of high speed data on Verizon's network that I've never noticed being throttled, and if I would use all 5 GB, which I never have, I still have data but the speed would drop to 3G or slower. I have a Moto G7 phone--their phones are very affordable and they have frequent flash sales on various phones on their website. The voice network quality is outstanding, as is the data network availability and speed. I've used Virgin Mobile, regular (not prepaid) AT&T, and Straight Talk in the past and none of them even come close to the quality and value for the cost compared to Total Wireless. I very highly recommend Total Wireless.
Verizon's purchase of TracFone is worrisome to me. I dropped straight talk after 7 years because of the bad customer service. I'm now on AT&T prepaid $75 plan which is $60 with autopay and it's incredibly better. The perks include Better customer service, 5G access, Visual voicemail Unlimited everything with a hotspot. Hard to beat that deal!
