I finally found a solution: MOFI4500-4GXELTE-SIM4_COMBO

It' a cellular router and was $315. I took the SIM card from my tablet and upgraded the data package for it with AT&T for $20/month - our shitty satellite internet service was $70/month and we usually bought $20-$30 worth of additional data every month.

This thing is BAD ASS. We've been streaming movies, YT and the kids are online gaming without any issues for about two weeks now. Cell service is marginal at best at our house. 2 bars on the phone on a good day. You could get yagi antennas to mount on the roof if your signal is REAL bad. I thought I'd try the unit with the antennas it came with before getting the yagi's and we don't need them apparently.

If you have a cell signal at your rural/remote location, I highly recommend this.
