Which is the best mobile network in the DR?

Good evening!
I'm planing to travel by car through the country. I was wondering, which mobile network has the best availability in the Dominican Republik? The northern and eastern parts are of special interest. I don't expect to have any problems around Santo Domingo...
Are there any areas, which have no mobile network at all?
Thank you very much.
