1. Emergency

This is very helpful in emergency situation, even our service provider have no range we can do it at-least any of the service provider have range. Just dail 112 it will search for a service provider and give you access to emergency no. We can dial 112 even if the phone is locked.

2. Hidden battery power

Suppose you don’t have charger in hand and you are waiting for an emergency call. Nokia phone normally have a reserve battery inbuilt. To activate it press *3370# then your phone will restart and gave you 50% charge. The hidden battery will automatically get charged on the next charging.

3. Make your stolen mobile useless

All the mobile phone have a unique serial number what we called it as IMEI number. Type *#06# the phone will display a serial number note it and keep somewhere safely. When ever the phone get stoled give the service provider the serial number so that they can de-activate phone so the stolen person can’t do anything with it. All of us do it we can avoid phone stealing.
