Erasing One’s Device

No matter what you do with your device once you are done with it, either by giving it to someone, reselling it or even responsibly disposing of it, it is important that you first erase your sensitive information. Do not assume who ever uses the device after you will do the right thing and erase the device.

The first thing one should do is take a backup of the device in question so that way it will be easy to recover and move your data and respective settings to your new one.

Once the backup has been taken you will want to reset your device. Doing this resets it to factory defaults. If you are prompted to ender your cloud password, do enter it as this will break any links to your cloud account that is linked with the device.

To reset ones device you can do the following depending if you have an Apple iOS device or Android.

For an Apple iOS device you can do the following steps:

  1. Open Settings
  2. Click on General
  3. Click on Transfer or Reset
  4. Choose Erase All Content and Settings

For Android devices you can do the following (NOTE: These options will vary depending on the mobile phone manufacturer):

  1. Open Settings
  2. Click on System
  3. Click on Reset Options

Sim and External Cards

Besides resetting ones device it is important to consider what you do with your sim (Subscriber Identity Module) card. Carriers issue this card as it allows your mobile phone to be identified on the network as well as make a data connection.

When you erase ones device the sim card will still retain information about your account and it is still bound to you. If you are moving your number to a new device reach out to your carrier to assist you in transferring the sim. If moving your sim card to a new device is not possible then it should be retained and physically destroyed.

Many new phones have what is called an eSIM. This is a virtual sim card instead of a physical one. When the phone is reset the eSIM is also reset in the process.

Lastly on some Android devices SD (Secure Digital) Memory cards are used to add additional storage. These can be removed from the device if you will be disposing of it. This memory card can then be re deployed in ones new mobile phone. This card could also be placed in a USB memory card adaptor and used in ones PC. If the Memory card will not be used, just like the SIM, it is recommended that you physically destroy it.
