First, Verizon is the only cell system that works in rural areas. AT&T, T-Mobile, and any other GSM based 3G/4G system concentrate on the cities and interstates.
Wilson makes the very best "amplifiers" or repeaters on the market. You can get them for vehicles, not just for buildings.
No cellphone can have more than 300mW (just under 1/3Watt) output by federal law, so it's all about antennas. Android phones by major manufacturers seem to have better internal antennas than the iPhones.
I don't know how big of a place you have, but if you're using a utility vehicle or tractor, then a Wilson rig will work, but you have to be close to the rig when you talk.
Text messages will get out in places that voice will not due to the frequencies they operate at and the fact that they are a "burst" of info rather than a stream.
Oh, and those little "bars" that show cell signal strength? They only pertain to the voice side of the device and even then they are routinely manipulated by the carriers to indicate a larger service area than is actually there.
