Get emergency help
The emergency number worldwide for cell phones is 112. This number can be used to contact any network where ever you are and it can be dialed even if the keypad is locked.
Unlock your car remotely
If you have keyless entry locks on your car and you are locked out, all you need to do is contact someone who has access to the second set of keys and key fob. Hold your phone a foot from your car door and have the person on the other end hold the spare key fob next to their phone and press the un lock button. You guessed it, the door un locks!
Find hidden battery power
If your phone shuts down due to low battery power, you can access the hidden battery power in your phone. To activate the hidden power, dial *3370#, your phone will restart with a 50% increase in battery power. The reserve will be recharged the next time you charge your phone.
