The silent evolution of SMS messaging services

How the once highly praised technology now become finally available for everybody


image0 Some years ago there was considerable excitement around the use of short message service (SMS) communication solutions, particularly in the ICT for Development context and in countries across Africa. And indeed, some remarkable projects emerged from this: using SMS for HIV/AIDS education in Uganda, providing farmers with relevant information via SMS in India, China, Indonesia and Nigeria, and enabling convenient money transfers over SMS in Kenya and Tanzania.

In Nicaragua SMS communication for the good, has been used least in two projects, both related with health issues:

  • Chat Salud a SMS service for every teenager in Nicaragua to inform themselves about “embarrassing” topics on sexual health, sexually transmitted diseases and domestic violence.
  • In cooperation with the University of Engineering (UNI), the Nicaraguan Ministry of Health (MINSA) uses a solution they call “Telemedicina” in the remote areas around Waslala with about hundred volunteer health promoters in each community to track basic vital signs of sick people in the communities in order to be able to take proper decisions about hospitalization in urgent cases.

Until just recently the used technology has been RapidSMS, a solid Open Source tool to interact and communicate over SMS with people and process the obtained information. This was good, but in all projects a team of professionals was needed to build the individual solutions, and it was required to dispose of a GSM modem as an endpoint.

This has changed now: A simple smartphone with internet access (over wifi or 3G) can be used as an endpoint to the regular cellphone network in any country. Easy communication flows can be designed comfortably using a nice online configuration tool to draw an understandable diagram.

All this happened almost quietly, just days ago, when the African start-up company Nyaruka together with the UNICEF Innovation Centre published under an open source license a completely new version of an automated SMS messaging and processing application: RapidPro.

Anyone can use it and, because the source code is available, developers can extend the functionality. The software can be run on an independent server or hosting can be acquired as a web service called TextIt.

It became incredibly easy to set up a SMS survey or reminder application for anybody. No big expenses in hardware nor special deals with telecommunication companies are needed. Within minutes a new application can be created. And this can freely be used for such noble causes as providing better health in developing countries, but also is a great tool for surveys in social sciences or marketing and can be used for any kind of crowd-sourcing data collection for anybody. Think about it, there are too many good use cases where this can benefit.
