Cell Booster Phone Test Mode
Click on the manufacturer of the cell phone you’re attempting to increase your signal for. The link will provide you with a list of models on how to reach test mode on your phone and get a numerical value of your cell signal.
Please notice that signal strength, measured in decibels (dB), is expressed as a negative number and can range from about -30 to -110. On certain phones, the number may show as positive in test mode. In such cases, convert it to negative. For example, 60 dB is actually -60 dB. The closer the number is to zero, the better signal your phone is receiving. Thus, a reading of -60 dB is a stronger signal than -75 dB.| Apple | Blackberry | Samsung |
