3G mobile phones supporting software applications have become ubiquitous, the world over. This has naturally resulted in proliferation of a varied range of software applications which work on any 3G phone, regardless of the architecture of underlying cellular network. There are certain situations wherein one needs to stay aware of telephonic conversations, text messages of one's near and dear ones; i.e. kids, wife, girlfriend or husband. It is in these situations wherein mobile spy software comes handy.

Spy software works just like any other mobile software. It requires a one time installation on the host mobile.
Once installed, the software's functions can remotely be controlled by sending sms from another mobile. Through the sms interceptor feature, one can instantly receive a copy of text messages sent and received by the target mobile, i.e. the one on which mobile spy software is installed. The target's conversations can also be intercepted by activating the call interceptor feature. One can activate or hibernate the software or any features thereof, simply by sending short commands to the target mobile.

In addition of serving as an sms spy and a phone call interceptor, mobile spy software also works as a spy microphone. This means that you can remotely switch on this feature and listen to the environment of the target phone or spyphone, right from the comfort of your own living room. The best thing is that once installed on the host mobile, there will be no trace indicating that the host phone has become a spyphone. Even if the user of the target phone changes his/her SIM card, the functionality of spyphone is unhindered. In that case, the software automatically sends a text message on the snooping mobile informing about the new number in use.
