Every car owner at least once in his life got into a situation where the keys remain inside the locked car. Do not rush to panic or, worse, beat the glass.

If you have a second set of remote key at home, take your phone, calmly dial the number of someone from the household and ask to use the key directly from the house, first take it to the mobile phone, and at that time keep your device at a distance of about 30 see from the car door.

Thus, your phones will create a kind of portal and serve as a guide for the key. This will help you save time, material costs and open your car in two accounts. The distance in this case is absolutely irrelevant: if you are at least a hundred kilometers from home, if you can get through to the person with the spare keys, you can open the car or even the trunk!

It is not regrettable, but every second owner of a mobile phone at least once in his life became a victim of theft of a cell phone. The situation is very unpleasant and the matter is often not even in the cost of the device, but in information.

If you live in a big city, we advise you to take a responsible approach to the issue of the safety of your property, and, of course, does not interfere once again to be safe. If you still lost your phone, it is best to immediately block it. For this you need the serial number of the cellular.

Dial the following combination of digits * # 06 # on the phone, then the code of 15 digits will be displayed on the screen - this is a unique number that is never repeated and is assigned by the manufacturer individually to each device. Write it down and keep it in a safe place. If your phone is lost, call your mobile operator and report this code, after which the cell phone can be blocked.

After such a phone will not be use. Of course, this is not a guarantee that you will get it back, but at least the attacker will not be able to use your phone in its original form.

If an emergency situation overtakes you, being anywhere in the world, you just have to dial the short number “112” from your mobile phone and the phone will automatically search for the emergency number within the available networks in this region.

Even being outside the network coverage area, having no funds in your account and being in a foreign country, you will necessarily be connected to the necessary emergency service by this number. Moreover, this number can be dialed without even removing your phone from the lock!

The most pressing issue for all mobile phone owners is the battery charge. Fortunately, there is a life hack for this problem too, although this advice is intended only for Nokia owners.

The fact is that it is in Nokia phones that there is a hidden battery reserve. To activate it, you need to dial a combination of digits * 3370 #, after which the phone will reboot using the backup battery and the battery charge will increase by 50%. The backup battery, in turn, will recharge the next time the battery is charged.
