Editor's Notes
- We will talking about the need of SMS in your application in the context of Nepal and what you need to know about making use of SMS as a medium in your application.
- Before we start, lets start with the basis stats of the mobile environment in Nepal. As of Jul 2014, number of mobile users stood at 84% and 33% of them use internet and majority of them use 3G. As for smart phone, we still don’t know the real numbers. We can atleast assume that majority of those using 3G belong to smart phone users. But it doesn’t cover the whole population – which raises questions on if your users belong to that category only or beyond. Also 3G coverage in Nepal is not very high. We have to understand our target users and their target locations.
- Based on our target users and target locations, we can see if our app solely based on internet is adequate or not. If our target areas is rural areas without 3G network, then we might have to consider other medium like SMS.
- SMS might be one of the options based on your target users and locations. It might not be. Also the usage of sms depends on the type of content/services you are serving from your app. If it’s rich content, then sms is definitely not for you. SMS could be either push or pull based service. Push sms is where you send SMS directly to your customers like notifications or some alerts, send info through SMS. Similarly there could be pull sms where the user send information to you, seeking services like sending sms to take certain action like querying for the weather or temperature status.
- What can you do with sms? Request for agriculture
- How do you do that? There are quick solutions like smssync, an android based application, which turns your phone into local sms gateway. SMS gateway can send and receive sms and send to your application. This could be quick fix if you are planning to use sms in your app. Your app can now send sms to this mobile with smssync installed, which sends the sms to the designated URL, which can then process the process and send sms notification accordingly.
- Though there are shortcomings, you can use it for quick testing and during the making of the MVP. There are services called VAS which gives you such services. VAS are authorized organisations who deal with the telecom and help you get the codes and provide apis to send and receive sms.
