Pomme question

I've never fished Pomme before. I've hunted there several times on the Boliver end, but it's been a few years. Can someone tell me a good place to launch with descent parking and such, and does the upper end of the lake have much cell service around? I'm not usually one that has to be glued to my phone, but I'm on call this weekend and I can work from my boat if I have to with my hotspot if there is good cell/data service on the lake. If not, I'm going to LOZ where there is alway a cell tower in sight or a condo wifi to hitchhike on if necessary. Best case, I don't get paged and work doesn't interrupt my fishing.:fish

The st. park by the NEMO bridge is a nice launch. Bolivar landing on the lower end is nice but if fish are biting well can be tough to find a parking spot. Pittsburg landing is a up and down hill walk to the parking area and I do not care for the steepness of the ramp at the st. park marina. There is a couple of others but I am not familiar with them. Cell service is spotty there is areas of good reception.
