Phone Test Mode Overview
If you do not see your phone model listed:
• Try using the field test mode for other phones from the same manufacturer.
• Not all phones have a user accessible field test mode. In particular, many GSM phones.
• Some carriers lock out/remove field test mode.
• If the code for your phone is not listed then we do not know what it is.
What the numbers mean:
Signal strength is a number ranging from roughly -50 to -105 (your
phone may show as a positive number).
Closer to zero means a better signal, i.e. -50 is better than -100.
