This tiny device, not much bigger than a matchbox, backs up all the contacts held on a mobile phone SIM card. If you are wondering how this might be useful, just imagine all the numbers you’d lose if your phone was lost or stolen.
The process of backing up contacts is easy. Just slip your SIM card into the slot on the side of the device, type in your PIN number, press the Menu button, then the Enter button. Wait a couple of minutes and all your contacts are safely stored on the 8KB of memory.
It can store up to 250 numbers and you can back up your SIM as often as you need.
