THE JAMES BOND TRICK
If you short-circuit theleft middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying.
*#06# to check the IMEI (International Mobile Equipment Identity)
*#0000# shows the software version
*#3370# - Enchanced full Rate Codec (EFR) activation. It will automatically
restart.
*#3370# - Enchanced full Rate Codec (EFR) deactivation
*#4720# - Half Rate Codec activation. It will automatically restart.
*#4720# - Half Rate Codec deactivation

Enchanced Full Rate will give you much better sound quality when you enable
it. The new Enhanced Full Rate CODEC adopted by GSM uses the ASELP
(AlgebraicCode Excitation Linear Prediction) compression technology. This
technology allows for much great voice quality in the same number of bits as
the older Full Rate CODEC. The older technology was called LPC-RPE (Linear
Prediction Coding with Regular Pulse Excitation). Both operate at 13
kilobits.(but you take up more space on the network, so they can charge you
more) - Talk-time is reduced with about 5%
The following codes are the standard GSM codes for various network services.
Most Nokia phones have easier ways to activate them through the menus. Check
the guides for your model.
