Looked through your IG, very cool. Who/what are you using for internet access while on the road? I'm interested in trying to travel more when working remote but trying to make sure I end up with a decent connection each day seems like it could be challenging.
I used Calyx hotspots for 2 years. The hardware they offer is garbage and Sprint coverage is spotty.
The Franklin R850 is outdated and unreliable. I had one and hated it. The ZTE hotspot they had after that wasn't terrible but the charge controller was bad and would overcharge the batteries. Now they're back to the terrible R850 since ZTE is banned. I can't speak to the R910 but after my experience with the R850 I never want to own another Franklin product.
I may get another unlimited Sprint or T-Mobile hotspot since they're good for high bandwidth activities (eg streaming video) when the signal works.
There is such a thing as unlimited, one of the people on our T-Mobile account is at 147GB of tethering with another week to go. People have successfully used both the plans I mentioned for home internet.
If your not in a very congested area, any of these plans should work just fine.
