First of all, you need to ensure that you have the Google Messages app installed on your device. Currently, that’s the only app that supports this feature. If you already have it installed, ensure that you’re running the latest version of the app by updating it from the Play Store.

Now, chances are that you haven’t received your ‘invitation’ to RCS because you device doesn’t know which SIM to activate. If you’re on a dual SIM device, this is what’s holding you back.

Thanks to the Google Messages app Help section, we get a little insight towards how to enable this feature on your dual sim device.

To get Google Chat on your dual-SIM device, you need to have calls and data set to the same SIM card. With that, you might need to go to your device settings and configure the SIM settings accordingly.

This function is a little different depending on which device you’re using but here’s the general procedure for doing this.

  • Open Settings and select Network & Internet.
  • Tap on Mobile Network.
Select Mobile Networks
  • Select one of the two available SIM cards, the one you’d like to use.
  • You should then see options for Call preference, SMS preference, and a Mobile data toggle.

Toggle all the settings to the selected SIM.

And that’s it. Your device now knows which SIM to use for RCS. And if you open your messages app, you should see this pop-up below, notifying you that RCS is available for your device.

Should you not want to go through the above process, you could also simply eject the SIM card you don’t want RCS on and only leave the single SIM you want. You can pop it back in once RCS services are enabled on the preferred SIM in the port.

And that’s it! We have tried this process on 3 different devices and it worked on 2 of them so you might want to go into this with your fingers crossed.

If you’re lucky, welcome to the wonderful world of Google Chat on your dual-SIM device. Go on and share those images over the Messages app instead of having them compressed by WhatsApp.
