In prosecution of suspected offenders, secret services may use so-called silent SMS. Dasentschied The Federal Supreme Court (BGH) in a written veröffentlichtenBeschluss. In so-called silent SMS, a text message is sent to one-handed, but it is not displayed re so that user does not notice anything. Neverless, device establishes a radio connection to NächstgelegenenMobilfunksendemasten. This allows investigators to locate device undetected and create motion profiles.

With his Revisionvor to BGH, plaintiff made numerous procedural obstacles. Under Anderemargumentierte He, for silent SMS, re is no legal basis. Demwidersprach BGH. Thus, in case of a being communicable offence of "significant importance", Criminal Procedure Code allows locating EinesMobilfunkgeräts "with technical means". At introduction of DerVorschrift in year 2002, silent SMS had not yet existed, but legislator had taken account of technical progress with formulation "technical means" and kept provision with Thatonlyone for new locating methods open .Inviolability of apartment is not touched
According to BGHwerde with silent SMS also does not touch inviolability guaranteed by Basic Law of apartment. It is possible that DasMobilfunkgerät will be located in apartment. But that's a coincidence. A deliberate intervention in privacy of apartment was not silent SMS, were judges of Karlsruhe.
The German authorities increasingly use silent SMS. For example, Federal Office for Protection of Constitution in second half of 2017 has sent around 180,000 of such clandestine messages to mobile phones from suspects.
