Two common reasons behind this problem are that RCS Android messaging is either not available in your area or that it is an error that is causing it. As always, we are going to go through a step by step guide on how to fix this problem on your smartphone.
1. Compatibility and availability
Sanaz Ahari, Android Messages Product Manager, recently confirmed that RCS messaging is now available to all users residing in the United States. Other than that, Google noted that the long-awaited functionality is only available in France, the United Kingdom and Mexico. You can ask your operator for updates on the same, but other than that, there is not much you can do. RCS Messaging will work on all Android phones that support current text messaging.
2. Default messaging application
First, download Google Messages. RCS messages only work on this one, and no third party messaging app is supported at this time. This will most likely change in the future.
Google Messages should be the default messaging app on your phone. Open Settings and go to Manage apps under Apps. Tap the menu icon here to select the default apps.
Press Messaging and choose Messages here instead of any other application you are currently using.
It is possible that the default Android operating system has changed after installing a different launcher or messaging app. Check whether RCS messaging works on your smartphone or not.
3. RCS messaging status
Check whether the RCS chat function is enabled or not. If so, check whether the status indicates that it is connected or not. Open Messages and tap Settings under Menu.
Tap the chat features and enable the Enable Chat Features option.
You will be asked – Let the application always run in the background? Tap Allow.
Go back one step and tap the chat features again. If you see this screen, RCS messaging is not available in your area. Then, if available, you will be asked to enter your mobile number (main or first SIM number only) and validate it. If it is already done, the status should appear as Connected.
Several users see Connection there. The functionality is not very stable at the moment, and waiting a few hours seems to work. RCS messaging should work automatically again. What you can try is to turn off the chat features and then turn it back on to see if the RCS messaging chat feature works or not.
If you see the Disconnected state, press the Retry button to reconnect. At this point, also make sure the internet is working on your phone or try to connect to another Wi-Fi network, just to be sure.
Note that the chat features must be enabled on everyone in the group you are posting to, and that everyone is using the latest version of the Messages app.
4. Google Hangouts and Fi Conflict
Do you use Google Fi to connect to the Internet and did you also install Hangouts? Open Hangouts, tap the menu icon to select Settings> Accounts, then select your Google account here.
Make sure that messages are disabled in the Calls and SMS section of Google Fi.
5. Clear cache and app data
Old data such as the cache could be responsible for Android RCS not working on your phone. Open Settings and select Manage applications under Applications. Search for messages here and open it. Tap Clear Data at the bottom of the screen.
Tap Clear cache, and then tap Clear all data.
Did it help? Otherwise repeat the same process, but this time for the Carrier Service app. It will depend on the carrier you have subscribed to. Restart the phone once after this step.
Note: I recommend that you update the Messages and Carrier Service app to the latest version before proceeding to the next step.
6. Disable SIM 2 on dual SIM phones
Most Android phones nowadays support dual SIM card. Unfortunately, several users have discovered that using a second SIM card prevents Android RCS messages from working properly. You will need to delete or temporarily disable it until a fix is released.
Android RCS is not designed to work on two separate numbers, and when you pair it with one, the other creates a conflict.
To deactivate the second SIM card, open Settings> Dual SIM. The option may vary depending on the make and model of your phone, and Xiaomi phones don't even have any way to deactivate the second SIM card.
If you can't live without a second SIM card, make sure the same SIM card saved with the Messages app is used for calls and data. Again, the options vary from smartphone to smartphone for that.
The future is here
RCS messaging is the future of text messaging and will soon be available worldwide on all Android smartphones. I hope Apple supports it too. In this way, you will be able to communicate with those who use iMessage. Until then, you will have to wait for it to be made available in your country.
