1) Emergency numberThe Emergency Number worldwide for Mobile is 112. Ifyou find yourself out of coverage area of yourmobile network and there is an emergency, dial 112and the mobile will search any existing network to establish theemergency number for you, and interestingly ...this number 112 can be dialed evenwhile the keypad is locked. Try it out.
2) Locked the keys in the car? Your car has remotekeys?This may come in handy someday. Good reason to own acell phone: If you happen to lock your keys in the car and the sparekeys are home, call someone on your cell phone. Hold your cell phoneabout a foot from your car door and have the other person at your home pressthe unlock button, holding it near the phone on their end. Your carwill unlock.Saves someone from having to drive your keys to you.Distance is no object. You could be hundreds of miles away, and if you canreach someone who has the other "remote" for your car, you can unlock thedoors (or the trunk).Editor's Note: *It works fine! We tried it out andit unlocked our car over a cell phone!"
3) Hidden Battery powerImagine your cell battery is very low, u r expecting an importantcall and u don't have a charger. Nokia instrument comes witha reserve battery. To activate, press the keys *3370#Your cell will restart with this reserve and the instrument will showa 50% increase in battery. This reserve will get chargedwhen u charge your cell next time.
Caution:
There is nothing like a reserve battery in nokia or any other cellphones. The code you have given (*3370#) is a pre-programmed code to change the active "speech codec". This code changes the speed codec to half rate. When half rate speech codec is active, phone uses about 50% less battery than the normal full rate speech codec, that's why the phone shows an increase in battery power. Also note that using a half-rate speech codec also reduces the voice quality.
