PER RIM:
Cell broadcasting is designed to enable wireless service providers to use SMS text messaging to send information to all BlackBerry� devices in a specific geographical area simultaneously. You can receive cell broadcast messages that contain a specific type of information by subscribing to a cell broadcast channel that provides that type of information. Different cell broadcast channels send different cell broadcast messages. For example, one cell broadcast channel might send regular weather forecasts while another might send traffic reports

If you have high speed internet you can buy and install a network extender. Wont help with EV data coverage, but will give you MUCH better cell phone reception within 5,000 square feet of the extender
