Your mobile phone can do more things than you observe at first. Here are some hidden functions and combinations of keys on the phone that you had no clue, but can be very useful at the right time:

1. 112 is the number that can be called the emergency phone. Interestingly, this number can be called even if the phone keys are locked.

2. They say that if you are away from home and you locked the keys in the car, you can solve this problem with a simple call from a mobile phone. The condition is to have spare keys (with remote), which are in the hands of the person called. What should I do? Ask the person called to close her phone keys while you keep your phone at about 20 cm from the car. Other press remote keys and your car door opens. Works with the trunk door. Anyone tested this?

3. What do you do if you need to talk on the phone and run out of battery when the world is your dearest? Well, it seems that mobile performs a backup load, which can enable the combination * 3370 #, completing the battery at a rate of 50%. Each time you upload your phone, load and reserve, you can use in a situation "urgent".



4. How can you prevent immediate access to your data if your mobile is stolen? Dealers of mobile phones are not disclosing information that would be very helpful in this case, that have no interest to prevent the use of mobile, even if the device is no longer in the hands of original owner. You need to know your phone's unique series and you can do this by typing * # 06 #, without pressing other buttons. Code will appear on your phone, unique in the world that you should keep in a safe place and if you reveal operator declaring phone stolen. Series that enable permanent blocking of furniture, which can not be used or if the SIM card is changed. A test, go!

These codes will work on most Nokia Mobile Phones to activate/deactivate advanced hidden functions that you can’t change through the phone menu
