Just know with Visible (and probably other MVNOs) you'll get downrated. We just switched to Visible and I get LTE a lot (was on T-Mobile just prior and it seemed like it had been years since I'd seen LTE show as my network, it shows most of the time on Visible but will change to 5G pretty frequently during less busy times - work phone has Verizon and it gets full 5G in same area). Which downrating so far doesn't bother me, I don't use my phone all that much, and generally if I start using the internet, like watching a video it sort of "wakes up" and then it'll stream like 720p without issue once it gets going. There are other perks (unlimited Hotspot, 5Mbps on the cheap plan 10Mbps on the Premium, Premium gets 50GB of priority data per month, and you can add an Apple watch line for free on Premium or $10/mo on the cheap). We switched because of T-Mobile's BS and coupled with the unlimited Hotspot could ditch a tablet line, so we went from $90/month to $40. I'm seeing if they'll give us the extra $5/line cheaper since we ported from T-Mobile (they have offer of $15/mo for 5 years if you port from T-Mobile). I think you can save $5/$10 a month if you have Verizon home internet as well. We had it for a while and it was ok, unlimited data but it wasn't consistent and they updated their modem/router thing to remove features (also had some odd limitations like could set only a single schedule for a device, so couldn't set like weekday and weekend schedules; you could bridge it to your own router so could get around things like that). It was good enough that my niece and nephews could play like Fortnite on it.
If you do a year you can get the Premium down to like $32.50. I'll be really curious what they'll offer at like Black Friday or Xmas (Mint used to offer 2 years of service for the price of one if you bought a phone).
