Now you can trigger alarms with dual SIM cards


Workers in forestry and rail are among those who regularly find themselves in areas with poor mobile coverage. A weak signal is a genuine safety risk, if an accident occurs or a threatening situation arises, the ability to raise an alarm cannot be taken for granted.


We are therefore delighted to announce that Crystal Alarm now supports dual SIM cards from different mobile operators on Android devices. By connecting to two networks simultaneously, the app significantly increases the likelihood of a reliable connection, ensuring that help can always be reached when it is needed most.


Want to improve your coverage and peace of mind with dual SIM support? Get in touch with Crystal Alarm to activate this feature.
