When we need to clear our mobile phones?

Should you have used cell phones a great deal, you must have stored plenty of data on your phones, involving some extremely confidential contacts, text and voice messages, photos, videos conversation history. If you itch to trade in your phone, have it donated or given away, you should definitely learn to erase your personal data in order to protect them from being revealed before you hand it over. Otherwise you may suffer more than your data’s being laid bare, which’s your identity will likely be stolen. As long as you haven’t closed your account, it’s possible for others to make calls via your phone, and you’ll need to pay for the terrible consequences. But if you dispose of your private data one by one, that will be way too time-consuming and inconvenient. What's worse is that if you merely erase them, they may still be restored with professional tools.

Your photos, videos, pictures, music and those downloaded will often be stored inside the memory card if your cell phone has one. Your contacts and text messages will usually be stored either on your phone or in the SIM card, which your phone will include one when you use a Global System for Mobile Communications (GSM)’ wireless carrier. Even if you have deleted the data, they haven’t gone elsewhere, sticking still around where it used to be. Pure operation of wiping data isn’t equal to erasing them entirely.

In this case, precautions need to be taken to ensure the security of your personal data.
