This warning system would make it possible to send out SMS alerts to all mobile network users with no need to know phone numbers, in case of emergencies. However, Seehofer emphasised that he only saw the cell broadcast system as an addition to the warning systems already in place. The text alerts could supplement other methods of issuing warnings, such as sirens, smartphone apps and radio bulletins. Other countries, such as the Netherlands, Greece, Romania, Italy, or the USA, already use this system to send widespread emergency alerts. “Barely functioning sirens, no early evacuations and data protection prevented warning text messages to all affected citizens.”
