Nokia network monitor (
Netmonitor) or
Monitor Mode was a hidden mode on most
Nokia cell phones used to measure network parameters. Additionally there are measurements for phone and battery temperature and other phone specific measurements and tests. The mode can only be activated over a special
FBus, or
MBUS cable; or in some cases over infrared. Free software exists on the internet that allows one to activate this mode. The first step is to select a Nokia Phone like
Nokia 3310 that has network monitor then activate the monitor. To activate, download software such as
Gnokii, gammu, logomanager, or N-Monitor by Anderas Schmidt and connect the mobile with a
FBus cable. In Nokia phones you just activate the monitor and not upload it to the phone, as it is already present. Some of
Nokia Series 60 phones have a
Field test application installed or it could be installed with privileged permissions or on rooted phone. Such mode and programs are available on Android and iPhone devices. ==Options==
