What smartphone, service, hotspot, booster do you use?

My wife and I have iPhone 8’s and Verizon. We use them for everything while on the road, use iPad when we want a little bigger screen. When CG WiFi is not available we will use the iPhones for internet access even for the iPad’s. I second the notion that if you are dependent on access you should get service from Verizon and ATT but even then sometimes you can’t get either.
