Selection and installation of a message application
The MIUI shell installed on Redmi 10 uses Google’s own Messages app or Xiaomi’s system solution by default. However, standard software isn’t always convenient or functional. Many users prefer to install third-party solutions that offer a more flexible interface and advanced spam filtering capabilities.
If you decide to change a standard app, you'll need to download it from the Google Play store. Once installed, the system can request permission to use the default program, which is critical because without this status, incoming messages may not appear in the new interface.
When choosing an alternative, note that RCS is supported, which allows you to send multimedia and read delivery statuses, as in instant messengers. It is also important that the application has minimal access rights without asking for unnecessary permissions.

Set up Internet access and MMS
While regular text messages don’t require an internet connection, multimedia messaging (MMS) and RCS Chat protocol require network access. On the Xiaomi Redmi 10, access point settings (APNs) are usually applied automatically, but sometimes manual corrections are required.

Use Do Not Disturb mode wisely: If SMS does not arrive, check if the sender has been blacklisted or if the notification limit from unknown numbers is worth the MIUI security settings.

If you don't send messages after all the settings, the problem can be deeper. Often, cleaning the app cache helps. Go to Settings → Applications → Messages → Storage and click Clear Cache. Don't confuse it with clearing the data, otherwise the correspondence history may disappear.
Another common cause is the phone's overcrowded memory: If the free space runs out, the system can't create a new file for an incoming or outgoing message.
