馃嚢馃嚟 Early Warning System, Cambodia

Watch it in action

Cambodia is a country consistently ranked as one of the most vulnerable to the effects of natural disasters.

In order to deliver timely and potentially lifesaving information to people in disaster prone areas, an Early Warning System (EWS) was conceived by the organization, People In Need (PIN) .

People in Need realized that the EWS needs to be accessible to all Cambodians, regardless of literacy and Internet connectivity issues. They decided to look into a solution which uses voice based messaging for alerts and Interactive Voice Response (IVR) for registration.

With help from the Royal Cambodian Government, the Telecommunication Regulator of Cambodia (TRC) and the National Committee for Disaster Management (NCDM), it was regulated that the Early Warning System must be provided free of charge by the Mobile Network Operators (MNOs) in Cambodia.

With the pieces of the puzzle coming together the problems that still remained were:

  1. How to connect to the MNOs for user registration?
  2. How to send out automated alerts to people at risk in the event of an emergency?

The major mobile network operators in Cambodia each provided a SIP connection, but lacked the technology that People In Need required to handle user registrations and send out automated flood alerts.

Somleng SCFM is an open source contact center platform and call flow manager designed for Somleng and Twilio. Somleng SCFM comes complete with its own REST API for managing contacts, callouts and phone calls and can be configured to send out alerts and listen for inbound calls through Somleng which provides an open source implementation of Twilio's REST API.

Unlike Twilio, Somleng gives you full control over where and how inbound and outbound calls are routed from/to. Somleng is configured to send out alerts and listen for inbound calls via SIP connections provided by the local mobile network operators.

To summarize the technology:

  1. Citizens register for the Early Warning System by calling a short code and answering the prompts to select their address. The call is first received by a local mobile network operator then forwarded to Somleng which handles the IVR.
  2. Flood sensors which detect water level heights, trigger alerts and callouts via Somleng SCFM.
  3. Somleng SCFM sends voice alerts through Somleng to the local mobile network operators.

馃嚫馃嚧 Cash Assistance Programme, Somalia

In Somalia returnee households from Dadaab refugee camp in Kenya and vulnerable households in Bay and Bakool received emergency unconditional cash-based transfer assistance package to help them meet their needs during the current drought period.

In order to share information and get feedback about the program, a voice-based messaging solution was proposed. In the proposal voice messages and surveys would be recorded in the Somali language and delivered to the household head by mobile phone calls.

The price for terminating a call through Twilio in Somalia is $0.7680 per minute . To date more than 75.8 K minutes worth of calls have been sent out which would equate to $58,238.98 on Twilio.

In order to reduce costs and promote local businesses, Africa's Voices Foundation in conjunction with UNICEF Somalia partnered with Hormuud , a local MNO in Somalia. In comparison, Hormuud's pricing is between $0.04 and $0.07 per minute.

Somleng SCFM was again used in this project to provide Africa's Voices Foundation with a dashboard for scheduling callouts and managing recipients. Automated voice messages were sent to beneficiaries via Somleng through Hormuud.

馃嚞馃嚬 Promoting behavior change for the prevention of childhood malnutrition with mobile phone technology

Originally authored by Estuardo Pineda, T4D Officer, UNICEF Guatemala. Modified for spelling and clarity.


In Guatemala, 5 out of 10 children under six years old suffer from chronic child malnutrition. Early childhood, is the greatest window of opportunity to support the development of children's brains, bodies, and abilities through comprehensive interventions. Additionally, Guatemala is a multicultural and multilingual country, with 22 languages, including the Mayan, Spanish, Xinka and Garifuna. The use of the Spanish language has predominated in healthcare services, making it difficult for Mayan speaking population throughout the country to access public services every day.

With the objective of improving the nutritional conditions of children, adolescents, pregnant and lactating women, UNICEF Guatemala is coordinating with Government institutions at national, departmental and municipal level the implementation of comprehensive strategy to address stunting in Huehuetenango, Quich茅, Chiquimula and Alta Verapaz.


Given the current situation of COVID-19, there are actions that must be adapted to the new scenario, including the use of innovative solutions to reach the population through virtual platforms. The use mobile technology as a catalyst tool can accelerate the achievement of nutritional results for Guatemalan children.


Coraz贸n contento is a free-volunteer subscription mobile service that seeks to promote and strength early childhood development through a comprehensive intervention, with flexible models that take into account cultural differences and the reality of the country. Using text messages (SMS), social media, as well as voice messages (IVR) to provide an integrated package of information about: health, hygiene, sanitation, maternal nutrition, breastfeeding, complementary feeding and parenting guidelines directed delivered to caregivers (mothers, fathers) of children, as well as pregnant and lactating women and primary health care workers in seven native languages (Q始eqchi始, Poqomchi始, Ch始orti始, Q始anjob始al, Chuj, Akateko and Ixil).

To this day, UNICEF Guatemala has achieved:

  • An alliance between the Ministry of Health and the Academy of Mayan Languages of Guatemala to aligned the service with the National Crusade for Nutrition.
  • The development of 170 integral messages translated to seven native languages.
  • More than 6,000 mothers and pregnant women from Quich茅 and Alta Verapz subscribed to the service.
  • Endorsement from the Ministry of Health.


RapidPro is an open source software platform that allows for building and scaling mobile-based applications from anywhere in the world. RapidPro is designed to send personalized messages with responses analyzed in real-time.

Somleng is an open source cloud communications platform which can be used to deliver IVR messages through local mobile network operators.

Voice Messages are recorded into RapidPro and delivered to the beneficiary's phone via Somleng. Together RapidPro and Somleng are powering the way governments and development partners connect, engage and collaborate directly with the most important - and often most marginalized - voices in their communities.

馃嚥馃嚱 Powering Cloud Communications, Mexico

In Mexico, Somleng is powering C3ntro Telecom's Cloud Communications Platform as a Service (CPaaS).

Watch it in action


People in Need (PIN)'s mHealth project, implemented in cooperation with the Ministry of Health (MoH) Zambia Telecommunications Company Limited (ZAMTEL) and powered by Somleng, is an innovative and one-of-a-kind intervention in Zambia.

The project uses voice recorded messages to overcome illiteracy barriers and to improve maternal and child health and nutrition outcomes, influence attitudes and enhance knowledge and skills of women about the importance of key health and nutrition behaviors. The messages were incorporated into dialogues performed by a local drama group that created culturally appropriate characters to provide an educative, engaging and entertaining service, effective at changing people's behaviors. These dialogues were designed typically around specific topics such as health, nutrition or hygiene. The set contains key messages related to maternal health and nutrition as well as nutrition and health of children aged 0-6 and 7-24 months.

The messages were designed to cover the most important behaviors in order to provide timely information that supports the mother to provide the best possible start to their child's life during the first 1000 days most critical days (from the inception until the child is 2 years old). The pilot project targeted 100 women in Mongu and Nalolo districts in Western Zambia and aimed to prove that the concept is relevant and effective in the Zambian context.

How it works

  1. The messages are designed, consulted and approved by PIN and MoH.
  2. The messages are translated to the local language, performed and recorded by a drama group at a radio station or recording studio.
  3. PIN engages health staff from the health facilities the self-registration of women.
  4. The beneficiaries receive the voice messages as phone calls.
  5. PIN performs a study and collects endline data to measure impact of the intervention.


  • At endline, 89% of target women were aware that the recommended birth spacing is 2-3 years compared to 81% at baseline.
  • Furthermore, after they received the voice-recorded messages, 99% of women were aware of exclusive breastfeeding and its significance compared to 81% before the intervention.
  • After they received the mHealth service, 72% of women were aware of the recommended length of breastfeeding (12-23 months) compared to only 62% at baseline.
  • At endline, 88% of women were practicing vitamin A supplementation compared to 80% before the start of the intervention.
  • Moreover, 74% of women were taking pregnancy supplements every day at endline compared to only 60% at baseline.


The study found that the mHealth intervention has had a significant impact on knowledge, attitudes and practices of women with regards to maternal and infant nutrition and health. The level of satisfaction suggests that the service fills an important gap, is effective at changing behaviors and is highly relevant in the Zambian context. The results suggest that the intervention contributed to improved maternal\ and child health outcomes and led to changes in key nutrition behaviors. With several upgrades and improvements, which are currently underway, the project indicators may improve further.

馃嚦馃嚨Blockchain based cash distribution pilot, Nepal

Tokenized aid distribution platform to support vulnerable communities, Nepal


In January 2023, UNICEF Nepal launched a blockchain pilot to support 1,500 vulnerable households with cash distribution in the Madhesh province, Nepal . The cash distribution supports landless families, daily wagers and families with disabilities, with children under the age of five. The pilot uses an open-source blockchain based solution called, Rehat - developed by Rumsan , a UNICEF Venture Fund company, from Nepal.


This pilot sees a collaboration of two UNICEF Venture Fund portfolio companies, Rumsan and Somleng . Rahat is using Somleng's Carrier Bypass IVR feature . to support beneficiaries in the cash distribution pilot with information and later to receive feedback from the beneficiaries directly. This feature was developed by Somleng as part of the 2022 Growth Funding round by the UNICEF innovation fund.
