If your income/ job depends on reliable internet - cell network based internet access will not work for you unless you limit yourself to camping near cities with 5-10,000 or more population, or near major interstates.
People whose income depends on reliable internet, yet who want to travel almost anywhere in this country, even Mexico or Canada - use satellite based RV internet.
It isn't cheap. It is going to cost $6 to $7 thousand for the initial equipment and setup, and between $80 and $250 per month for the service. If you want 2 mps download, and 1 mps upload - that is the high end costs. Most of us would not be satisfied with that level of service in our home. Especially for graphic intensive usage.
$7,000 for setup, $2,400 per year for service is a budget breaker for me. But if $15-20,000 per year income or more depended upon reliable internet access 24/7 365 - then it would be worth the investment.
Because some of the cell network based solutions listed above can easily run to a yearly cost of $1,500 and an equipment cost of $1,500 or more.
Here is one company which has been in the business for several years -
RVDataSatDo be aware that like a cell phone/network based solution must be within near line of sight of a cell tower, a satellite based solution must be within direct line of sight of the satellite.
While storms don't usually hurt a cell based signal, they will interrupt a satellite signal, as will trees and other obstructions.
But if you are going to camp more than 20 miles from a cell tower, satellite is the only solution.
