Do all cell phone towers work together in transmitting signal?

You have several cell phone companies and they have their own towers and sometimes share towers, well whenever your on your cell phone and its AT&T or something does it only use AT&T towers or does it just use whatever towers are closest no matter what company it belongs too? Like say, im using an AT&T phone and theres only US cellular towers around does my signal bounce off those and then AT&T is charged for using the US cellular Tower? Is that what Roaming charges are?

1. They only use their own towers. If you connect to another tower ... it's roaming.
2. ... when travelling outside the geographical coverage area of the home network roaming is a general term referring to the extension of connectivity service in a location that is different from the home location where the service was registered http://en.wikipedia.org/wiki/Roaming cellular operator A & B may be mutually exclusive competitors & may not share cell towers & other services at all, in which case the premise that all cell phone towers work together is false likewise, A & B may share towers / services ... depending upon the agreement between them
