`Your Nokia cell phone can be programmed to pick up radar speed traps, when programmed your cell phone picks up the radar and alerts you on the message alert tone.
1. Enter your menu
2. Select settings
3. Select security settings
4. Select closed user group
5. Select on
6. Enter 00000
7. Press ok
8. Clear back to normal, within a few seconds your phone will display a radar sign with five zero's next to it. It is now activated.
Unfortunately only Nokia phones have this function. Cell info display needs to be de-activated. Settings -> Phone Settings -> Cell Info display
Each time you turn off your phone, or even each time you loose contact with your carrier, you´ll have to activate it again... It is done by steps 1 through 5, but the number (00000) will be already on the field as default. If you put the number 500 in the closed user group, and you go out of a store with detection ports thy will go off.

#746025625# says SIM CLOCK STOP ALLOWED or similar, depending on your SIM card. Newer SIMs have a feature called 'clock stopping' that allows the phone to save energy -- it is a kind of sleep mode for SIM cards. Not all versions of software support this. You cannot turn the SIM clock on and off, the phone will do it automatically if the SIM supports clock stopping.
