Camp operators have no control or knowledge of your equipment or provider. For instance, my old samsung flip dumb phone with verizon works all over my camp, while the next guy with the same phone but a different provider may not. Then another with a smart phone with another provider again works just fine. How could we list that?
Are your wishes for 4g text & inet? If these are a must have, then plan on 'camping' in a city.
All we can say is in our location nearly all phones work for voice, some for higher usage, a few not at all.
Get a Wilson 2 way repeater booster if it is critical to you to have service. That is, if you want to leave the city behind.
