The free messaging service, set up by the charity and mobile network provider Nepal Telecom, will target users according to their location, offering them potentially "life-saving" information on weather and health hazards in time for the approaching monsoon.
The 7.8-magnitude earthquake sparked avalanches and landslides in northern Nepal, including on Mount Everest base camp, and killed more than 8,000 people, leaving thousands more homeless and in desperate need of food, clean water and shelter.
"This life-saving service provides real-time information and warnings on flood risks, disease outbreaks and health advice to geographically targeted communities at the touch of a button," Dhakhwa said in a press release.
According to the country's telecom authority, 87 per cent of Nepalis use mobile phones, with Nepal Telecom boasting around 11.9 million subscribers.
However, network coverage in the country's remote, mountainous villages remains weak, with frequent disturbances during the heavy monsoons, expected to begin next month.
