It seems Google hasn’t yet decided on which is going to be its primary messaging app or service. It already has a few like Google Hangouts and Google Allo (and more). Aside from these Google is also providing RCS messaging to select telecommunications providers. RCS stands for “Rich Communications Service” and it is an upgrade to the general SMS standard.
SMS service is generally used by spammers these days because most of the people use instant messaging apps like WhatsApp, Facebook Messenger and Telegram to send and receive messages. A big reason why people don’t use SMS is because they have to pay for every message. For example, if I send a text message using SMS from India to America, it cost me Rs. 5. But since I already have a broadband connection, I use WhatsApp, which is free, and there is no limit on the number of characters I can send. Besides, I can also send rich media.
RCS brings rich media to the normal SMS service. Google already provides RCS through the Sprint carrier on select smartphones. Now it has partnered with Telenor to bring RCS messaging to Europe and Asia for Android devices.
In order to be able to use RCS messaging, you can either upgrade your existing messaging app or you can download a dedicated RCS app from Google Play.
Some of the primary RCS features are group chat, high-resolution photo sharing and read receipts. The service will be powered by the Jibe RCS cloud from Google. The RCS messaging service to Telenor subscribers will be introduced in Norway, Denmark, Sweden, Hungary, Montenegro, Serbia, Bulgaria, Pakistan, Myanmar, Bangladesh, Thailand, Malaysia and India.
