Losing or Disposing of Your Device

Take care when disposing of, selling or repairing your machine
It is a good idea to factory-reset your mobile phones before disposal, re-sale or repair. Delete all accounts and wipe/remove all data (file, photo, emails, contact, calendar).

If you lose your device or data
Contact your mobile network service provider immediately to avoid unauthorized use of your device and reset your ITSC password and/or other passwords of your personal accounts saved on the device.
