What is mSpy? How does it work?

mSpy is a background smartphone application that secretly records and logs SMS messages, Call history, calendar tasks and memos; bugs meeting rooms or whatever surroundings; tracks GPS locations of the phone in real time and displays all routes on a convenient map. The software installs directly into the phone you wish to spy on. 
However, physical access to the device is only needed for initial download. All settings may be adjusted remotely anytime online right from your web Control Panel. 
After the installation process is completed, as soon as in 20 minutes, all data, even those deleted, are uploaded to your private Control Panel account which is available from any PC or phone browser.

Immediately after making a purchase, you will receive an e-mail with detailed instructions for installation and setting up.

NB: The target phone must have access to the Internet, and be compatible with mSpy. Check if your mobile device is supported. Please note, mSpy works on a range of platforms including BlackBerry and iPhone!
