To spy on any cell number you suspect you have to install the Mobile spy software in that cell; it will not load any application in the targeted cell. So they will not get any suspension that they are being monitored. This software works on the number and starts uploading all the details in the web. The calls made by them and received by them, the messages sent by them received by them , the images they sent and received, the sites they browsed in the net , and even the contacts they have and the recipients phone number, the message sent time and date etc. All the details will be uploaded in the cell spy web site. By entering in the site we can have all the data in detail.
