Trust me when I say I know 5G isn’t everywhere, but I think it will be. I purchased the Inseego M1000 used from eBay and popped a Visible sim chip in it. Initially, I used a Verizon sim chip and drove from Joshua Tree Nationa Park to Big Bend National park, and not once did I see 5G appear on my screen.
Overall I am happy with Visible, I created a Party and now my bill is only $25 a month for unlimited internet in my car. Scroll down to see my first speed test results! :)
