Is there cell phone service with Verizon at Long Pine Key Campground?

Yes I have verizon and I could get a signal there, but not further into the park...only a few more miles down the road and its gone.

If you have Verizon, it's phenomenal! 3 or 4 bars of 4G LTE!

I have Google's Project Fi, which uses T-Mobile and Sprint towers. I had a signal only about 3% of the time, so it sounds like you're in better hands with Verizon.

Yep,what Wendy m.said.

Yes, Verizon also works intermittently past Ling Pine Key.
