Text messaging or SMS(Short Message Service) is well known for alerts and notifications. Be it in a crisis or a marketing campaign. It is actually the most powerful medium for quick and effective dissemination of messages.
SMS does have its shortcomings such as unreliable delivery or spoofing but it still remains the most ubiquitous of communication technologies which fed the frenzy of a USD 100 Billion global market in 2014.
Impressive statistics aside, SMS comes with its inherent power of simplicity and availability. It is native to every mobile phone, smart or otherwise. It works from day one of the service, and everyone knows how to use it. 7 Billion of them!
But, we have a new phenomenon growing and that is the Internet of Things(IoT). Essentially IoT consists of sensors(they see and hear), actuators(they do things) managed by a controller. A control system with internet thrown into the mix.
Experts estimate Billions of devices(sensors and actuators) will be connected. The most popular device in this fray is the mobile phone. Use of SMS now takes IoT to another level. Every mobile phone with SMS becomes a sensor and an actuator.
This is akin to using SMS for online banking authentication. A authentication code is received via SMS(sensor) and the user enters the code when prompted(actuator).
Using SMS allows IoT to reach users around the world and not only in developed cities and countries. A rice farmer in a developing part of the world would appreciate control over his crops via IoT if he could use a technology like SMS. Expecting him to watch dashboards or install apps on smart phones is not feasible.
The world is catching up to this concept, I think. No wonder the Global (application to person) A2P SMS market is expected to reach USD 70.32 Billion in 2020.
At the end everyone should be able to benefit from IoT, all 7 billion of them. SMS is one way.
