How to Enable Mi Messages on Xiaomi: The Complete Guide

Owners of Redmi and POCO smartphones often face situations where a standard text messaging app stops working correctly or requires forced activation. In the Xiaomi ecosystem, Mi Messages is responsible for this, which provides not only regular SMS sending, but also support for modern data protocols. The problem often lies in regional restrictions or failures after updating the MIUI and HyperOS shell.

Activation of this service allows you to use advanced functionality, including sending high-quality multimedia without compression, characteristic of standard media. MMS. No service on. RCS-You won’t be able to see “printed” or “read” statuses in conversations with other Android users. In this article, we’ll take a look at all the nuances of settings, from basic activation to solving complex login errors.

Many users confuse the system application with third-party counterparts, which leads to improper notification and synchronization configuration.The system component is deeply integrated into the shell, so its operation affects the receipt of confirmation codes from banks and delivery services. The correct configuration will save you from missing important notifications and delays in correspondence.

Mi Messages differs from standard SMS and Google Messages

The fundamental difference between Mi Messages and conventional SMS is data technology: If classic messages use signal channels on a cellular network, Xiaomi’s branded service relies on an Internet connection (Wi-Fi or mobile traffic), which allows files of any size to be transferred instantly, without being limited by the limits of the carrier.

Unlike Google Messages, which is now pre-installed on many global firmware versions, Mi’s native app has closer integration with MIUI’s system security features, which automatically filters spam using local antivirus databases and blocks unwanted numbers at the system level, rather than simply hiding them in the Spam folder.

It's important to understand that for advanced functions to work, both interlocutors do not need to have smartphones of the same brand. RCS (Rich Communication Services), which uses Mi Messages, is a universal standard. However, for maximum communication quality and the work of all emojis, it is desirable that the interlocutor also has an Internet chat.

Step-by-step activation of the service in the settings of the smartphone

The process of turning on the service may vary depending on the version of the operating system, but the basic algorithm remains unchanged. SIM-A card that will be used by default for voice and the Internet without an active network connection, activating Mi Account messages is impossible.

To start the procedure, go to the settings menu and find the section responsible for applications. In some versions of the firmware, it may be called "Apps", in others it may be called "System Apps." Find it in the list of Mi Messages and open it. If the application is hidden, search by settings by entering the word "Messages".

Inside the app menu, select Settings or Chat Settings, and you will be prompted to enable Internet Chat or «RCS-The system will request confirmation of the phone number by sending a hidden SMS Make sure that there is a minimum amount on the balance sheet or a tariff is included that allows sending international SMS, The activation server may be located abroad.

⚠️ Warning: The activation process can take up to a few minutes. Do not turn off the smartphone screen or switch to other heavy applications at the time of registration of the number, so as not to interrupt the handshake protocol with the server.

Set up RCS and chat functions over the Internet

Once the basic service is successfully activated, you can access the fine-tuning of the RCS protocol. This is the setting that turns a regular caller into a powerful messenger. In the message settings menu, find Chat settings. Here you will see the connection status: Connected, Connected, or Disconnected.

For comfort, we recommend activating the Send as Text option if the Internet connection is unstable, which ensures that your message will be delivered to the recipient even in the event of a Wi-Fi break, automatically switching to the SMS channel. However, it is worth remembering that delivery via SMS may be charged according to your tariff.

💡

If reading indicators do not appear at a particular contact, check if it has Invisible mode or traffic saving in the settings of the message application itself.

Notification settings are also worth a special attention. Mi Messages allows you to flexibly customize sounds for different types of events: new message arrival, delivery and reading, especially for users waiting for important confirmation codes or business correspondence.

Solving Common Connection Errors

The most common problem users face is the endless Connection status or login error, often due to a conflict of network settings or port locking by a carrier, try temporarily disabling Wi-Fi and activating exclusively via 4G/LTE mobile Internet, which will eliminate problems with corporate firewalls or routers.

If the problem persists, you need to clear the cache and application data. Go to Settings → Apps → All apps → Messages. Click on Clear and select Clear All Data. Importantly, this action will delete the correspondence history stored locally on the device, so back up important dialogs first.

Another cause of disruption may be time desynchronization. The encryption protocols used in Mi Messages are extremely sensitive to system time accuracy. If the clock is lagging or even a few minutes in a hurry, the security server will reject the registration request. Set the Autodetect option in the date and time settings.

⚠️ Note: When resetting the application, be sure to check whether the background activity restriction for system processes is worth it. MIUI Aggressive energy savings can kill the sign-up process immediately after the screen is turned off.

Synchronizing messages between Xiaomi devices

Xiaomi's ecosystem allows you to synchronize messages between your smartphone and tablet, as well as some laptop models, using a single Mi Account. Make sure all devices are logged in to the same account, which allows you to see your correspondence history and respond to messages from the large screen of the tablet.

Sync is set up via the Mi Cloud service. Go to the Mi Account settings, select "Mi Cloud" and make sure that the Messages slider is activated. Sync is in the background and requires Internet access. This is convenient when you switch to a new phone: you just log in, and the entire history of the correspondence is restored automatically.

💡

To sync all devices, two-factor authorization in your Mi Cloud account must be enabled, which increases the security of your personal data.

Not only are text messages synchronized, but multimedia attachments are synchronized if space is allocated to them in cloud storage. Free 5 GB may not be enough for a complete media history, so the system can offer to expand the tariff plan or synchronize only text.

The impact of energy saving on the service

MIUI and HyperOS shells are known for aggressive power optimization, which often blocks the background processes of system applications. If Mi Messages stop arriving notifications or messages are delivered with a delay, first check the battery settings. Go to Settings → Battery → Problem Search or Activity Control.

Find Messages and set background activity restriction to No Limits mode, which will allow the app to maintain a constant connection to the Push Notification server even if the smartphone screen is off. Without this step, the system can freeze the app after 15 minutes of downtime.

Also check to see if the global Ultra Battery Saver mode is on, and in this mode most network functions, including background message synchronization, are suspended to save power.

⚠️ Warning: After a firmware update, the power saving settings may reset to factory (aggressive) settings. Always recheck the permissions for key applications after a major system update.
