NL-Alert siren test across the Netherlands — no need to panic!
The Dutch government will conduct a national test of the NL-Alert system at 12:00 PM on Monday, sending a loud and attention-grabbing alarm sound to mobile phones across the country. Authorities emphasize that this is just a test.
Officials advise removing headphones or earbuds before noon to avoid discomfort, as the alert sound is intentionally sharp. This test is conducted twice a year on the first Monday of June and December to ensure the system is functioning properly.
NL-Alert messages will appear on mobile phones, in the NL-Alert app, and on digital information screens in public transport. Some people may receive the alert multiple times due to repeat settings or devices being set to the broadcast channels used for old and new devices.
Phones that are turned off, in airplane mode, out of network coverage, connected to old 2G or 3G networks, or linked to towers in Belgium or Germany may not receive the alert. Some older devices require users to manually activate NL-Alert.
The system is designed to quickly warn and inform the public about emergencies, including large fires, severe weather, natural gas leaks, and other hazards. By sending text messages through nearby cell towers, NL-Alert enables people to take immediate action.
