How to activate Google RCS messages on any Android?

RCS Messages (Rich Communication Service) is a service that has not yet been implemented in all countries ; It was designed with the intention of displacing the classic text messages that we know from telephone operator services such as SMS (Short Message Service) and thus try to compete with messaging apps like WhatsApp. Learn in this post how to activate Google’s RCS messages on your Andoid.

What advantages could Google’s RCS messages offer us?

Although we already enjoy excellent messaging applications such as WhatsApp or Telegram, the Google company is also willing to offer a new alternative with the RCS messages of its Google Messages application, launched almost at the end of 2019; which, like other chats, includes read receipts, response indicators or sharing multimedia files.

What do I need to be able to use these messages on my Android?

Despite the fact that the RCS protocol is not available worldwide (United Kingdom, France and Colombia, in Spain it is supported by Vodafone and Orange); It is possible to use the service between your contacts with the Google Messages app, as long as you have a mobile data connection or Wi-Fi signal to use the chat functions offered by said application.

Think that in case costs are limiting your ability to use applications, you can have the option of Google Pass and take advantage of promotions in applications of this brand.

This happens because RCS messages can be used between people (P2P) or also between companies and people (A2P); however, you must have the application updated and if you do not have it, you must download, install and configure it as your default message application.

The application is downloaded from the Google Play page at the following address: and then proceed with its installation, then You will have to do the following steps to make it your default application.

You look among the icons and press the “Settings” button and then go to the option “Applications and notifications> Advanced> Default applications> SMS application”; You will immediately see a screen where you can select the Google Messages application to be the default messaging application for your Android mobile.
