Currently, we have four data plans:
Grandfathered AT&T Unlimited Plus HotSpot Plan ($20/mo) - We've had this plan since November of 2017 when our MIA Membership paid off in a big way by warning us that this plan would be going away. And, if we wanted a good unlimited AT&T plan to grab a hotspot before it goes away. We did, and we still have this true unlimited plan today even though it went away in late 2017.
Verizon Unlimited Plan via Mobile Must Have ($120/mo) - This plan is via their data broker and is also no longer available, unfortunately.
AT&T Unlimited (5000GB fair use cap) via Mobile Must Have ($120/mo) - This plan is still available for $399 then $160/mo at the time of writing this FAQ (June 2021). It's a steep price, but unlimited data plans are hard to find these days. We locked in at $120/mo. NOTE: This plan is only available if you purchased your router hardware from Mobile Must Have.
Sprint Unlimited (800GB fair use cap) Plan via Mobile Must Have ($120/mo) - MMH only recently started offering this plan and we jumped on it! When it works, it works great! But, that's just the nature of Sprint / T-Mobile. The coverage isn't nearly as good nationwide as AT&T and Verizon, but it can save your bacon when it does work and our primaries don't. NOTE: This plan is only available if you purchased your router hardware from Mobile Must Have.
With the above plans, we primarily have the first two active most of the time (our router can have 2 modems active at once and bonded together). Yes, we pay a LOT for a versatile and resilient data solution, but our job depends on it.
