We recently visited Lake Fausse Pointe State Park in Louisiana. Granted, this campground is "out there" but I checked beforehand and Verizon's coverage map showed the area solidly in the 4G LTE coverage area. Long story short, this area has no coverage at all. As a matter of fact we had to drive 8.5 miles to a random spot on the road where we could pull over and make calls, check messages, etc. We had to do this every day to check on family members back home. The land is completely flat (It's southern Louisiana so....). Irritatingly, the "blue" network had coverage there. Been with Verizon for decades, but this may be changing soon. There's little excuse in 2021 to not have at least voice calling ability anywhere in the US. I included a map showing the obvious and grossly incorrect map. The green circle shows the location of the state park, seemingly (and falsely) swimming in LTE coverage.
Roussell, we never want you to consider leaving us. I completely understand how important it is to stay connected. Especially while traveling.
As you mentioned, this area does show some coverage. What make/model phone(s) do you have? Do you know if the settings were set to Roaming-ON? Are you still in this area?
iPhone Xs Max, cellular data roaming off. Not paying ridiculous roaming charges, especially in an area that Verizon is supposed to cover. No longer in the area, and won't be back for several months. We travel in our RV and hit spots all over the place that are similar; this is just one example.
The aversion to roaming tells me you've been a customer for a long, and the good news is that all of our unlimited plans will not bill for roaming as long as you are in the United States.
Turning Data Roaming on is a good first step. Additionally If you end up in an area with only Wi-Fi, let's ensure Wi-fi calling is on too. Here's how:
