Case Study: Tera
TERA, the relief application that revolutionized the IFRC
Humanitarian Emergency Communication Platform
Context
The humanitarian and disaster-response sector faced a critical communication challenge between the years 2000 to 2015:
Reaching vulnerable populations rapidly during emergencies when traditional communication channels were disrupted or unavailable.
International humanitarian organizations, particularly the International Federation of Red Cross and Red Crescent Societies (IFRC), required a scalable solution to communicate with affected communities before, during, and after disasters. The technical problem centered on enabling geo-targeted, mass communication without requiring access to individual phone numbers, while also allowing two-way engagement with communities affected by earthquakes, epidemics, floods, hurricanes, and other crises. Mobile networks existed, but there was no integrated platform capable of transforming telecom infrastructure into a real-time humanitarian response mechanism.
Humanitarian response teams were constrained by fragmented communication systems, delayed field intelligence, and limited visibility into rapidly evolving emergency situations. Traditional outreach methods, including radio, field brigades, and community mobilization, were slow, difficult to scale, and often ineffective in disasteraffected areas. The IFRC also faced architectural and integration limitations:
Any solution needed to work directly with telecom operators, scale to millions of users, respect subscriber privacy, support geographic targeting, and maintain reliability even in low-connectivity environments.
Additionally, organizations lacked an efficient way to collect community feedback in real time, limiting their ability to coordinate aid delivery, logistics, evacuation, and health-response efforts effectively.
Challenge
The SSI
Solution
SSI developed TERA (Trilogy Emergency Relief Application), an enterprise-grade humanitarian communication platform integrated directly with mobile network operators. The platform enabled geo-targeted mass SMS alerts to all active mobile devices within affected areas, without exposing personal subscriber information.
Beyond one-way notifications, TERA was designed as a two-way communication platform, enabling affected communities to respond, report needs, request assistance, and receive automated guidance through keyword-based workflows. The platform incorporated telecom-grade integrations, geographic mapping, multi-operator interoperability, opt-in/opt-out controls, and rapid deployment mechanisms.
- 100M+ SMS messages delivered across disaster and health-response scenarios
- Deployed following the Haiti earthquake and later across Mongolia, Pakistan, Sierra Leone, Kenya among many others
- Red Cross reported significantly higher reach than traditional methods alone
- High usefulness perception among recipients
- Became a replicable humanitarian response model across multiple countries
Impact
GIS-enabled geographic targeting · Mass SMS infrastructure · Two-way keyword workflows · Multi-operator telecom integration · Opt-in/opt-out controls · Rapid deployment architecture
