The major drawback to SIM Card Reader is that it works exclusively with USB card readers, and so it can't sync with ActiveSync or other similar programs.
So, programs like SIM Card Reader can recover these data, and reconstruct them to bring back your deleted SMS. Just like with information stored on your hard drive or flash drives, when you delete a message from your phone, it isn't permanently deleted from the memory, but rather the information is overwritten without deleting it entirely.
SIM Card Reader is an app capable of recovering text messages using your computer that you have deleted from your from mobile phone. Did you know that there are programs that can recover this information for you? If you didn't, perhaps you should keep reading.
Have you ever deleted an SMS on accident? Sure you have.
