I was recently talking to a friend who asked me if she should change her cell phone provider. She was happy enough with the service except for a few places in her house that never seem to get more than one bar of service.
Before changing service, it’s a good idea to know which network you are using. In the US, there are only three – AT&T, Verizon and T-Mobile. All other cell phone companies use one of those three networks.
