Like all great tools invented for our convenience, there are a lot of loopholes as well. Short messaging service or SMS is one of those tools that became a big hit for a lot of solid reasons. It was always easy to use and learn, plus it was very cost effective. As people began to use this extensively, it became a common way to communicate even till today. Now it is one of the cheapest ways to communicate instantly and marketers are cashing in on the economy. Companies can pay a small amount from their advertising budget and finally target those people who are potential buyers for their products. They have learnt ways to collect numbers that we widely share around so that they get spammed by advertising messages. This has become so common that people are forced to block messages or even change their numbers. Nevertheless, the demand for this service has made it more cost effective than ever before.
