Trinetra iWay app is designed to work with 3G/4G data connection (i.e.) GPRS. Ensure ‘background data services’ is enabled for data synchronization. Location capture is done with the help of network signal of the service provider. In areas where signals are not available, GPS, if available on the mobile phone, can be turned on. If GPS is also not available, status updates on activities can still be done on the mobile application by the field personnel.
