The SMS spy system doubles as an SMS tracking and monitoring system
as well as a cell phone monitoring system. However not all SMS spyware
systems can work as cell phone spyware. This is because some of the
earlier versions of SMS spyware were made specifically to monitor SMS
communications. But the developments in the technological world have
necessitated the need to have an all inclusive system that can track all
the communications from a cell phone. This is why the latest systems
that you can pick for SMS tracking can also serve as a cell phone
tracking system.
