Troubleshooting Connections

The top of your phone will indicate which types of signals you're using and the relative strengths of those signals. You'll also see an up-and-down arrow indicating an active data transfer. There's some variance with the model of phone you use, but most use standard symbols. Figure 3-1 shows a phone that is connected to a 3G network with a relatively weak signal. When data is being transferred over the network, the up-and-down arrow will light up. If you're on a CDMA network like Sprint, you'll see the letters EV where the 3G is located.
