If your business requires it AND you want mobile service regardless of where you are then your only option is to purchase or rent a satellite mobile phone while you are on your Alaska adventure.
Much of the Cassier Highway about 500 miles will not have mobile service. I broke down with a radiator leak about 200 miles from the southern intersection of the Cassier Highway and the Yellowhead Highway. Here was my exact location.
I had to offload my car from my cargo trailer and drive 40 miles back north to get to Bell II to use their satellite phone for tow service.
Satellite phones are not cheap but if you need to stay in contact that's your only choice.
