## What is a good signal strength number?

Cell phone signal strength is measured in decibels (dBm). Signal strengths can range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal. In general, anything better than -85 decibels is considered a usable signal.

### Is 3 bars of signal good?

The bars (or dots, depending on your phone model) don’t relate to actual decibel numbers — instead, they indicate the relative strength of the available signal. The key word here is relative. One bar indicates lower signal strength than two bars. And two bars represent lower signal strength than three bars — and so on.

2. Poor signal strength = -85 dBm to -100 dBm.
3. Good signal strength = -65 dBm to -84 dBm.
