Even though the Visible website shows 5G coverage at Monument Valley, my wife and I had "No Service" within about a 5 mile radius of our hotel.
We had a friend with us that had Verizon as their provider and they had 3 to 4 bars at 4G, so either Visible isn't 100% on the Verizon network or they have such a week signal neither of us could connect.
If anyone else has had the same experience, or did have Visible cell service, please let me know.
I'd love to visit Monument Valley again, but not without any cell service.
Verizon or any other big network carriers have inter network roaming. Visible dont have any roaming. Visible just works when there is verizon network.
