This Cell Phone Spy Data Extracktor looks just like an ordinary USB Flash drive. However, do not judge it by its size - it can be a powerful tool if used correctly. Just insert the SIM card in the device, plug it in the PC and you will be able to see all the numbers that were dialed through that SIM card, even deleted ones! This sim card reader can also restore deleted SMS messages and call logs, so nothing will be hidden from you. The manufacturer claims, this is the first SIM card reader in the world that can actually see deleted messages. More than that, this gadget can be used in peaceful ways, to make backup copies of phonebook or messages. Or you can make a full SIM card backup, buy a clean SIM card if needed and load your stored backup data on it.
Unfortunately, modern cell phones do not store messages on SIM anymore, and call logs are usually stored in phone's main memory. However, for those with old mobiles, or for the extra paranoid ones, this gadget will be very useful.
