Verizon Broadband Coverage in Joshua Tree Nat'l Park

I haven't been to Joshua in a few years and I'm planning on going soon. I'm wondering if any new cell towers have been added nearby and the signals reach some of the campgrounds.

I'm planning on camping on the south side of the park, but I'm willing to camp at other campgrounds within the park if they have a Verizon signal.

I'd like to hear from Verizon customers that have recently visited Joshua. Thanks!
