It seems that iPhones with the update to iOS 7 the Dutch mobile alarm system NL Alert supports. Users of all service providers get a carrier update, then a switch Noodmeldingen in the image.
The notifications users receive by default: the switch is turned off if users have the carrier update to install. In General, notification center, users need to switch to turn on the notifications to receive. It warns Apple – yet-in English – that receive those notifications can have a negative effect on the battery life of iPhones. The carrier update is only available for the new iOS 7, that Wednesday night came out.
The carrier update came Wednesday available for KPN, Vodafone and T-Mobile, know iPhoneclub. That Vodafone gave to customers with a suitable subscription with access to the 4g network. Users can the carrier update in the Settings to the sub-menu General Info. It is unclear when the next test takes place, in which iPhone users can try out and see if the notifications work. The organization behind EN Alert now says with the providers to see if the system works on iPhones.
Moreover, it seems that the government wants to get rid of the current technology, in which users own the phone to set the mobile alarm to receive. Recently, EN Alert tested with Wireless Emergency Alerts, a technique that in the United States already is used to allow mobile users to warn, for example, an approaching tornado. For this way of alarming the user has nothing to set: all phones support that standard, even iPhones. That is necessary because earlier this year showed that a small minority of the mobile phones receives the message, though that number is probably due to several factors is much higher.
EN Alert is last year already several times employed in, for example, burn in which there is danger that the release of hazardous substances. The alarm system works with a separate frequency, so the message will also be broadcast can be like the rest of the mobile network is down: it is like a hard shoulder on the motorway from the mobile network.
The message is sent to all mobile phones in a certain area, but the government can not determine who the message has been received. The system is since last year in use.
