In my location, we have a not-so-friendly duopoly of internet providers whose basic plans start at about $60/month. Over the past few years, I've selected the option that didn't require a 12-month contract or equipment rental, but I'm still not especially pleased with my options.
Recently, I switched to Visible cell service from another MVNO. Unlimited data hotspot is included with the following caveats: max 1 device connected at a time, speeds capped at 5MB/s (though I've measured higher). Visible recently announced that they are moving towards 5G coverage with no increase in price. (Presumably this would require purchase of a fancypants new device to use). Using data on my phone and not tethered, I am getting speeds of >75 MB/s in our area (large NC city). My wife and I pay $25/month/line.
Has anyone explored using a mobile hotspot as their primary home internet service? We have a seven year-old who now relies on our internet for full-remote 2nd grade education, which adds some complexity. If there's a service you've used that can help slash the monthly payments to a giant telecom company to zero, I'd love to hear about it!
