Only a few years ago, what was considered ‘innovative’ was using phones – in any way possible – to engage with communities. Time moves quickly, eh? With the advent of <\/span>chatbots <\/span><\/a>and <\/span>messaging apps<\/span><\/a>, using ‘plain old’ SMS seems relatively stone-age. Yet, in many communities where UNHCR works, mobile phones are one of the most prevalent and preferred channels of communication. Despite the wealth of software, products and services available – and the case studies demonstrating how SMS technology can be used – it still isn’t a ‘given’ that such services will exist or even be considered in different humanitarian contexts.<\/span> With this blog post, we’re trying to unpack and address the challenges of using SMS in humanitarian contexts. We’ve taken some of the best offerings available and demonstrate how you can set up a two-way SMS system within a matter of minutes.<\/span> <\/span><\/p>\n

Can’t I just use my mobile phone?<\/h4>\n

This isn’t as crazy a suggestion as it might sound – and should really be a first<\/g> consideration once you’ve <\/span>established that SMS is a preferred channel within a community<\/span><\/a>. Actually, many field staff are using their own phones daily to contact different community groups or vulnerable individuals who need dedicated support. There is nothing hugely different between using a personal device and a bell-and-whistles<\/g> platform for managing SMS – just that the latter is built for scale, and comes with some extra features.<\/span> Just as a middle-of-the-road cellphone allows you to create a contact list (and modern smartphones even facilitate the creation of groups), dedicated software for sending SMS messages en-masse contains specific functionality that facilitates working with a large number of contacts. Try sending 10,000 messages from your smartphone. Tricky right? Other than getting airtime for such a large number of messages, this would be very difficult to do using only your own handset. This is where software for managing SMS communications helps. <\/span> There’s been a wave of opportunities in recent years in terms of using SMS to communicate with communities or clients. Some have been driven forward by the aid and development sector, others have emerged out of commercial customer service in private enterprise. Within the private sector, there are often local companies\/organisations <\/span>that provide either products or services for managing SMS engagement with customers <\/span>(in Uganda UNHCR has worked with <\/span>SMS One<\/span><\/a> for example)<\/span>. While there’s simply too many of these to list here, your best approach when researching options for SMS services is to look for local providers in country<\/g>. In respect to commercial products, there are some like <\/span>Bulk SMS<\/a> and others that come at a cost. As such we generally prefer options designed around humanitarian\/development use cases – these often have open-source, free or favourable pricing models.<\/span> Within the aid and development sector, some products use defined parameters for sending\/receiving information such as <\/span>U-Report<\/span><\/a> developed by UNICEF. There are a number of service providers that provide software services to manage SMS in\/out such as <\/span>Viamo<\/span><\/a>, <\/span>RapidSMS<\/span><\/a> and <\/span>Envaya<\/span><\/a> (and many<\/g> more to choose from). <\/span><\/p>\n

Previously, UNHCR Innovation has tried to operationalise two-way SMS through the creation of a dedicated project: <\/span>‘Ascend’<\/span><\/a>. Because of our investment here, and our collaboration with FrontlineSMS \/ SIMLab as part of the CDAC Network<\/a>, we’re often inclined to use FrontlineSMS given its simplicity, ease-of-use and low barriers to entry for our field operations (we demonstrate this in our video below). But as always, check your specific requirements to ensure that the solution on the table fits your needs. Read more in <\/span>this blog<\/span><\/a>.<\/span><\/p>\n

Web Aggregators<\/h4>\n

There’s a lot of noise currently about how web-aggregator services such as Twilio<\/a> and Nexmo<\/a> are revolutionising the way companies, and organisations are communicating. But what actually are they and what do they do? From the Twilio website: <\/span>“Simply put, Twilio is a developer platform for communications. Software teams use Twilio API to add capabilities like voice, video, and messaging to their applications….Behind Twilio API is a Super Network, a software layer that connects and optimizes communications networks around the world”<\/span><\/i> Essentially what this means is that Twilio (and their competitors) are working with Mobile Network Operators, and other communications providers, to wrap potential communication options in an interface which web developers can speak to and work with. Rather than your organisation going out and brokering these different relationships with every company, you can rely on the web aggregators to do this. These aggregators are consistently brokering relationships with thousands of wireless carriers globally. Sounds great? It has the potential to be, but in many of the countries where UNHCR is operating, there are limitations to the services they currently provide.<\/span><\/p>\n

From scanning through the geographical options on some of the major aggregation platforms, there are very few countries in Africa and the Middle East in which two-way SMS is supported. To move away from one-way messaging towards building substantive<\/g> dialogue with communities the option of inbound messaging is a critical feature. This can only be implemented by using a local number and working with local operators directly. In some countries where we work, the telecommunications sectors haven’t gone through a liberalisation process and there are quite a few restrictions in place. As these aggregation services develop, their reach will broaden. The ecosystem of aggregators will develop, bringing new countries into their scope each year. For now, in the majority of humanitarian situations, you’ll most likely be better off working with Mobile Network Operators directly and with conveners such as the <\/span>GSMA<\/span><\/a>. FrontlineSMS<\/a> has actually put together a handy <\/span>pro\/con guide<\/span><\/a> on this to review before you choose your approach.<\/span><\/p>\n

<\/h4>\n

OK, let’s do this.<\/h4>\n

So now we’ve established that SMS is a channel our community is using, understand our requirements, and have done our background research on tools, We’ll now get started with sending SMS out to the community. As mentioned above we’ve spent more time working with FrontlineSMS than other tools – and are quite a fan of their <\/span>free desktop app<\/span><\/a> – so we’re going to show you how you can get started with this technology in this post.<\/span><\/p>\n

The right tools for the job.<\/h4>\n

In terms of hardware, the requirements are pretty bare-bones for FrontlineSMS. A computer (and it doesn’t have to be a good one – basically with access to the internet, and an updated operating system and web browser) and a relatively new Android smartphone should do the trick. And of course SIM cards as applicable. You might also want to send messages using multiple networks (different MNOs) which would require more SIM cards, and of course more phones.<\/span> In terms of software, you can download the <\/span>Frontline SMS desktop app <\/span><\/a>for your operating system. On the Android device, you’ll want to download the dedicated FrontlineSync App; this builds the bridge between the phone \/ SMS functions and the computer.<\/span> For those adamant in making things tricky for themselves<\/g> you can try using a USB modem<\/span>. We had some compatibility issues with a USB modem we’d attempted to use for FrontlineSMS. The protocol for connecting the modems is based on an old technology (serial port), the modem needs to be using this technology to be recognised. This wasn’t the case with our E3533 and as such<\/g> we were unsuccessful in using it. There are actually <\/span>guides on how to change the protocol on such a modem to Serial<\/span><\/a> that can function as a workaround. Our friends in the <\/span>Community Technology Empowerment Network<\/span><\/a> in Uganda also ran into issues with USB modems being unpredictably recognised. They found the connection with FrontlineSync really straightforward. In conclusion, we’d recommend sticking with Android devices and using the FrontlineSync application.<\/span><\/p>\n
