What is the Nokia Net Monitor?

The Nokia Net Monitor is a hidden menu built into Nokia’s mobile phones that allows the user to view, and in some cases change internal data about the phone’s hardware, software and its connection with the mobile network. It is primarily intended for Nokia’s engineers and network operators, however some interested users like to have it enabled, often “because they can”.

What can I do with the Nokia Net Monitor?

The Nokia Net Monitor consists of a number of ‘tests’, each test is a page (screen) of information, some of which are interactive (explained later). Some of these tests contain useful information, others might be useless to anyone other than a Nokia engineer. In short, here is a list of some things that can be done with Net Monitor (by no means complete)

• View information about the serving cell and neighbouring cells, such as accurate signal strengths, C1 and C2 values, transmitter power, timing advance
• Lock the phone to a channel of choice, or in other words select a base station
• View information about battery capacity and charging
• Find out the reason a call terminated or couldn’t be made
• Observe handover statistics
• View SMS send, receive and failure statistics
• View call statistics
• View and edit files on your SIM card (use your phone as a SIM card editor)
• Tweak audio values??
• View timers measuring the phone’s uptime and how long it has been connected to a network
• View information about the SIM card
• View information about the phone’s operating system
• Force the LCD and keypad backlighting on or off (useful for saving power or using phone as a torch)

Which Nokia phones have Net Monitor?

Most older Nokia phones, even analog phones, have a Net Monitor menu and it's relatively easy to turn it on.
The Nokia 2100, 3210, 3310, 3315, 3330, 3350, 5110, 5210*, 6110*, 6150*, 6210*, 6250*, 7110*, 8110, 8210*, 8250*, 8810, 8850*, 8855* and 9110 (and their various international versions) can all have Net Monitor easily enabled with a data cable and correct software. Phones marked with an asterisk (“*”) can also have Net Monitor activated through an infra-red connection.

The Net Monitor menu cannot be enabled by software on the recent phones such as the Nokia 8310, 6510, 6310, 6310i, 7210, 7250, 6610. These phones are known as DCT-4 phones. As it turned out, Net Monitor also present in their standard firmware (e.g. 6310i on pressing 15 in menu says "Shortcut not available", not "Invalid shorcut") and can be activated in them by replacing some bytes in the firmware, which, however, requires a programmer (box) and skills to work with it.
