Secret Codes for Mobile Phones

I now present some secret codes for you all, which you can type into your mobile phone to reveal some extra information and perform certain tasks. Remember you may be voiding your warranties by using some of them and can end up with a dead brick (having given the official disclaimer, play respectfully and you shall be safe)

UNIVERSAL

Staring with universal one

• *#06#

Typing this will reveal your IMEI (international mobile equipment identity) number across brands and handsets (it is a regulation). Every phone has a unique number and technically if your phone is lost it is possible to trace it via this number even if the thief changes the network.

In regions such as Europe this actually happens in practice, but in India things are little slack. While buying a phone always match this number (which comes on the screen) with the number printed on the backside (battery compartment) of your phone and the box in which the phone has come. All three should be same, indicating a genuine phone.

• 112

This is not really a code but an emergency number. You will be able to dial this number even if the keypad is locked and will be able to dial independent of the presence of the network, till any cellular network is available within the range. This will also work even if you have no credit.

NOKIA

Codes for Nokia phones:

• *#7760#

Reveals the production serial number, confined to work on the Series 40 phones, doesn’t works on all Series 60 phones.

• *#7780

Proceed with caution, this shall reset your phone to factory settings. Useful if you are debugging and confused if the problem is software setting related or hardware.

• *#0000#

Very useful, tells your current firmware version. In phones that support OTA (over the air) updating, you can simply update your phone firmware from the option menu that this will bring via GPRS/3G/Wi-Fi without connecting to PC Suite.
