After my friend’s phone got stolen I decided to install this app to protect my phone data from being hijacked and perhaps even to recover my phone if it would ever get stolen. I have tried a few similar apps before this one but they all seem to be running in the background and draining my battery. This app just waits for an SMS that is sent by their website after you login, and only then gets activated in the background. So no battery drainage! A lot of similar apps cost money to install, but with this one you only pay SMS credit when your phone is actually stolen. So no unnecessary costs!
I would recommend to install this app in case your phone would ever get stolen. Here is an example of how it works: https://www.youtube.com/watch?v=8gODZVr3pEA Good Luck!
