SMS is basically a telecommunication service which is designed to convey text messages from one cellular device to another. The era of sending and receiving letters has gone since the era of technologies has started to take over the world. It’s been decades since the communication system became dependent upon telegrams, landlines. During the 1980s, the idea of sending short text messages was invented. Later, it was designed in GSM standards. One of the oldest methods of communication is SMS which allows us to exchange a limited amount of informative messages between two cell phones. The first ever text message was sent in December, 1992. Though SMS is still a growing communication system spreading all over the world even in rural areas nowadays, challenges are also becoming very prominent as we are moving towards a better digitised environment dependent upon the internet. Several apps like Facebook messenger, WeChat, Viber, WhatsApp, and Telegram are dominating the market globally but as these are mostly internet-based, it’s not possible to use these everywhere. Places like hills or black forests still cannot have proper roads even where internet connectivity becomes a luxury.
