Test Mode Instructions

To determine where to find the best signal strength for your phone or cellular device, it works best to put your phone into it’s “Test Mode.” If you would like to put your phone in test mode, please reference the table below for the most up-to-date list of Cell Phone Test Modes, and the instructions will guide you through the steps of setting it up. If you have questions, or if you need assistance with putting your phone in test mode, contact weBoost Customer Support Department at 1-866-294-1660.

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.

In phone mode dial *3001#12345#* then press CALL. The Field Test Screen will appear. The signal bars will now display the signal in a dB reading. -51 is full signal, -105 is no signal. When testing phones in a 3G environment it is possible to determine the frequency being used by selecting: UMTS Cell environment, then select UMTS RR info. The screen displayed will list the Uplink and downlink Frequency in code form. Uplink frequency on the 850 MHz cellular band will list an Uplink Frequency code between 4132 and 4233 and a Downlink Frequency code between 4357 and 4458. If you are operating on the 1900 MHz spectrum the Uplink Frequency code will be between 9262 and 9538 with the Downlink Frequency code being between 9662 and 9938.
