What is cell coverage like for Verizon at TFF?

I am going to be renting a boat and do not own a marine GPS. Was considering using some mapping Apps on a smartphone and was wondering what the cell signal is like on the flowage for Verizon (or other carriers). Is there signal out there?

I have Verizon and have reception about 75% of the time on the TFF. Our guests that have AT&T seem to have the best signal.
