@caseyliss I know you're going to hate this answer but your hotspot needs are probably best solved by Starlink Roam: https://starlink.com/roam
$50/mo for 100GB and you can pause it (Standby Mode) at any time for as long as you want. Use it during tailgaite season then pause it for the rest of the year.
Starlink | Roam

Work and play at remote locations. Service starting at $50/mo.

@caseyliss NASCAR teams all now pretty much exclusively use starlink at the track - even saw a photographer setup with remote tethering (to her camera) at a test this week.
