You need to look into BGAN satellite internet, there are a few options, they are all pricey.

There are both fixed point(ie stopped and getting service) BGAN and in motion BGAN, even between them there is a vast difference in price. For a full in motion setup don't be surprised to spend upwards of 20k and still need some reliable power source for the bgan and any laptop/devices. That is just for the hardware.
