how much data is relaying while playing poker?

[riverspecialist]

Im planning to buy a yacht and sailing around the world with another poker player but we needs internet (satellite i assume?). Im having a hard time figuring this out, but it seems like there arent any reasonable unlimited access plans and the per/minute rates look like deal breakers too. They do offer per/data charges though which seems reasonable that is, assuming poker doesnt use much data. Anyone know how to figure out how much data im sending and recieving while playing x tables?
