The satellite service is going to be very slow compared to anything that you have ever done with cellular. Cellular speeds generally run 1-5MB up and 5-15MB down (3G vs 4G) while satellite internet speeds generally run 0.1MB up and 1MB down. That combined with the high latency (delay) caused by the distance a satellite signal must travel (22,300 miles x 4 for a complete round trip) makes satellite a poor choice unless nothing else of any kind is available.
It's also quite expensive as far as start up costs and the monthly services start around $70-$80/month. You can also forget about any of the "high speed" satellite currently being offered as those services are provided on a KA spot-beamed frequency and it NOT mobile.
That only leaves the old Hughesnet HN7000S service or Starband as a mobile choice.
