hi, and welcome.

you didn't mention how long the travel will be.

if it's a short trip, you might consider renting a satellite phone. not that expensive to rent - but you do pay $1.75/min for outgoing calls. free incoming.

these folks have info here:

and there are other rental providers.

good luck.
