Field Test is used to view various engineering parameters, such as signal
strength, frequency band, tower ID, etc. This page will capture the information
that I know about.
WARNING: Using the various programming and test features of the phone can
render your phone unusable of you are not careful. Do not attempt to make these
changes unless you are careful and know what you are doing. You *CAN* screw
CDMA & TDMA:
enter this real fast to enable field test mode:
Then you can go in and out of "test mode" with <MENU><left soft key>
You need to dial a number after getting into test mode in order to see anything
on the screen. The screen does not update when its idle.
The phone will ALWAYS start up in field test mode (probably not what you want).
You need to enter this code to disable "test mode" (you cant type this when on
the field test screen):
Alternately you can go into programming mode and enable/disable "test mode" on
(assuming you have not changed the security code - if you have, then use that
instead of the six zeros)
You need a data cable and software to modify the phone so that it has field
test capability (called Engineering Menu)
Most CDMA and TDMA phones have field test capability.
Current Nokia GSM phones do not have field test capability. Only special
firmware flashes have it. Some older phones do have field test (5190, 6190,
7190, 6340, 6340i)
To enable Field Test (called Netmonitor) so that it is a main menu entry:
Scroll to Field Test and enable it. Recycle Phone Power. You will then have a
new menu item "Field Test".
Main Menu Field Test Codes:
TDMA/CDMA/GSM (old): 1
TDMA (newer): 2101
Most Siemens phones do not have field test capability. The s56 is one of the few
You need a serial data cable and software to enable field test. You need to do
this for each SIM you will use in the phone.
