Is #5 true?
1. In Case of Emergency –
The worldwide Emergency Number for mobiles is 112.
Even if you find yourself out of the coverage area of your mobile network and you dial 112, the mobile will search any existing networks to establish the emergency number for you. Interestingly, this number can be dialed even if the keypad is locked.
2. Lock Your Keys in the Car? –
If your car has a remote lock/unlock device (and you have a second one, say at home - aside from the one on your keychain that's locked inside the car) you can call someone at home on their cell phone from your cell phone, hold your phone about a foot from your car door, and have the person at home press the unlock button on the device, holding it near the mobile phone on their end. Your car will unlock. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other remote for your car, you can unlock the doors.
3. Secret Battery Power –
Imagine your cell battery is very low, you are expecting an important call, and you don't have a charger. Nokia phones come with a reserve battery. To activate it, press the keys *3370#. Your cell will restart with this reserve, and show a 50% increase in battery. This reserve will get charged when you charge your cell next time.
4. Disabling a Stolen Phone –
To check your mobile phone's serial number, key in the following digits on your phone: * # 0 6 #. A 15-digit serial code will appear on the screen. Write it down and keep it somewhere safe. If your phone gets stolen, you can phone your service provider and give them this code. They will then be able to block your handset so even if the thief changes the SIM card, your phone will be totally useless.
5. Testing Your Microwave –
Put your mobile phone inside the microwave and close the door. Now call your mobile number from another phone. If your mobile rings you should throw away your microwave, since inside the oven, your phone should have zero reception, so if it rang it means the oven is not properly insulated.
