Silent SMS were initially meant to allow operators to acknowledge whether a mobile phone was switched on and test the network without advising the users.

By sending a Silent SMS, the location of the mobile is instantly updated. According to Mathias Monroy, a journalist with Heise Online, this surveillance technology is largely used because it falls in a gray area from the legal point of view, the law being unclear whether a Silent SMS can be considered as communication. This is useful, because if it is not a communication, it does not fall under the framework of the inviolability of telecommunications described in Article 10 of the German Constitution.

An SMS geofence can circle anything, or any area, such as a retail store, a stadium, or even a neighborhood. You can see an example of a customer giving permission to a brand to use their location for SMS geofencing below.
