If latency isn't a top-tier issue, a 5G hotspot is a viable alternative in good coverage areas. I switched from Charter to T-Mobile by selling myself as a sole proprietor seeking a business account. Immediate $35/month savings to $50 for unlimited (I used 150GB in my first month without hearing a peep) and ready to go into my van in a few weeks. Speeds are generally 250-300Mbit, dropping to 80Mbit during brief congested periods.
Oh, and no bullshit fees. It's actually $50 on the nose.
I've heard that there's a hidden monthly data cap, and you get throttled real hard if you reach it, but now that it's “unlimited” they aren't telling you what it is.
On T-Mobile? If you get the top tier unlimited plan, it is specifically the one with no limits or slowdowns. All the other tiers give you unlimited usage, but explicitly state what the limit before slowdown is. I have the unlimited one and have used at most 2TB in a month without any slow down. My dad only gets like 15GB (or whatever the lowest tier is) for the month before it goes slow as fuck.
