Modern flagship smartphones like the Xiaomi Mi 10 Pro offer advanced communication technologies, but basic features like texting sometimes require manual configuration. Device owners may face a situation where standard operator settings do not apply automatically, or the MIUI shell interface hides important options under the menu layers.
The configuration process depends on which application you use to communicate: standard Mi Messages or a third-party solution, such as Google Messages. In the first case, you get deep integration with the manufacturer's ecosystem, including smart category definition and ad blocking functions. In the second, the classic Android interface with minimalist design and synchronization through a Google account. The choice of tool affects the sequence of actions that must be performed to correctly operate the service.
In this article, we will discuss in detail all the stages of configuration, starting with the verification SIM-You'll learn how to activate advanced functions, such as: RCS-Chat, and what to do if messages stopped coming after the system update, understanding these nuances will make your smartphone a reliable tool for business and personal correspondence without failure.
Status check SIM-maps and baselines
Before you move on to complex settings inside the operating system, you need to make sure the physical health of the card and the correct installation. Xiaomi Mi 10 Pro is equipped with a hybrid tray, so it is important to ensure that the card is properly installed. SIM-The card was trimmed to the nano-SIM standard and sat tightly in the slot. If the contacts are contaminated or the card is not installed to the end, the device may not see the network, which automatically blocks the ability to send SMS.
To check the status, go to the Settings menu and select About Phone, then All specs or open the status immediately. SIM-Make sure that the card intended for messages is activated voice call and data transfer, as some operators require registration on the network through these channels to activate the message center.
Then check the automatic settings that come from the operator.
- 📱 Make sure the status bar shows the icon 4G or 5G, not just E or G.
- 💳 Remove and insert. SIM-card again, having previously wiped the contacts with a soft cloth.
- 📶 Check the balance of the personal account, as with a negative balance outgoing SMS frequently blocked.
⚠️ If after the reboot the smartphone continues to write “No network” or “Emergency calls only”, the problem may not be in the settings, but in mechanical damage to the tray or antenna module.
In some cases, manual entry of Message Center (SMSC) settings is required, which can be obtained from your mobile operator’s website or by calling support, and inserting an incorrect message center number will result in no outgoing message being delivered to the recipient, although incoming messages may come in normally.
Set up the standard Mi Messages application
The MIUI shell installed on the Xiaomi Mi 10 Pro uses its own text messaging app by default, and it has advanced functionality including ad blocker and smart sorting. To get started, open the app and follow the initial greeting instructions. If you haven't used the brand's devices before, the interface may seem overloaded, but the basic features are in logical places.
To access the basic settings, click on the three dots in the top right corner of the screen and select Settings. SIM-cards where you can select the default card to send messages if the device has two SIM-It also activates the delivery report function, which lets you know when a subscriber received your message.
An important aspect is the spam protection setup that is built into MIUI.
- 🛡️ Enable "Antispam" in the settings of the application for filtering advertising SMS.
- 🔢 Add important numbers to the blacklist manually through the lock menu.
- 📂 Configure the categories of messages (finance, transport, promo) so that they are sorted automatically.
💡
Use the Business Messages feature in Mi Messages to see company logos and quick action buttons instead of long text codes.
Special attention should be paid to the function Mi Message, which allows you to send messages over the Internet to other Xiaomi users for free. In the settings of the application, find the appropriate switch. When activated, the system can request the sending of a test paid SMS to verify the number - this is normal procedure, the cost of the message is usually minimal or free depending on the tariff.
Use of Google Messages and Alternatives
Many users prefer to replace the standard application with Google Messages, which offers a cleaner interface and advanced RCS protocol features. Installing this application from the Google Play store requires the provision of appropriate permissions to access contacts and SMS. Once installed, the system will suggest making it the default application - agree to this so that all incoming messages are opened in the new interface.
The main advantage of Google Messages on Xiaomi Mi 10 Pro is the support of Rich Communication Services (RCS). This technology turns the usual SMS to a full-fledged messenger with support for high-quality photos, typing indication and status "prints". To activate, go to the application settings (three dots) → Settings) and select a section RCS-chat.
The process of activating RCS can take some time and requires a stable internet connection.
- 🌐 Make sure that mobile internet or Wi-Fi is enabled to register with the service.
- ✅ Connected status indicates successful activation of advanced features.
- 💬 If the status is “Connect...”, try clearing the app cache in Android settings.
⚠️ Note: When switching between standard applications MIUI Google Messages and your correspondence history may not sync automatically.
If you use third-party apps, make sure they are given all the necessary permissions on the Android system. In MIUI, permission controls are strict, and without explicit permission, the application simply won't be able to access the communication module. Go to Settings → Apps → All apps, find your messenger and check the permissions section.
Solving problems with shipping and shipping
When a message freezes in a "Submit" status or returns with an error, it is one of the most common. The first step in diagnosis should always be to reboot the device. This action resets temporary errors of the network stack and updates the registration of the phone in the operator's network. If the reboot did not help, you should check whether the limit of characters in one message is exhausted when using a different encoding than the standard one (for example, if you have an emoji).
Often the problem lies in the overflowing memory of the phone or specifically the cache of the message application. When the internal storage is filled critically, the system can block the creation of new log files for SMS, which interrupts the sending process. Clear the space or use the built-in security utility to delete junk files.
For deep cleaning of application data, perform the following actions:
- Go to Settings → Applications → All applications.
- Find the application you are using (such as “Messages”).
- Select Memory and click Clear → Clear Cache.
- If it doesn’t work, choose Clear Everything (this will delete your correspondence history, make a backup!).
☑️ Diagnosing problems with SMS
The table below shows the basic error codes and methods to fix them that can occur on Xiaomi devices.
| Code/Symptom | Possible cause | Method of decision |
|---|---|---|
| Mistake 1 (Usual) | No network or weak signal | Switch network mode (4G/3G) or shift SIM |
| Not delivered. | Wrong SMS number | Check the number. SMSC customized SIM-map |
| Waiting for shipment | Antivirus blocking | Add an app to the Mi Protection exceptions |
| Multimedia failure | Mobile Internet shut down | Enable data transfer for MMS |
Setup MMS and multimedia messages
Sending photos and videos over MMS requires additional settings, since this protocol uses data channels rather than a voice channel. On Xiaomi Mi 10 Pro, you need to make sure that data is activated in the mobile network settings. Without mobile Internet enabled (Wi-Fi for MMS is usually not enough, although modern implementations may try to use it), the message with the attachment will not go away.
The APN settings must have the correct MMS values written in. Usually they come automatically, but when you manually configure them, you need to pay attention to the MMSC, MMS proxy and MMS port fields. These data are individual for each operator and cannot be universal.
Key parameters that affect the operation of MMS:
- 📶 Type of protocol APN must include the value of mm.
- 🔄 Make sure that the Traffic Saving mode for the message application is not enabled.
- 📏 The amount of the investment must not exceed the operator's limits (usually the 300-500 kb).
Why don’t MMS work over Wi-Fi?
If the automatic configuration of the access point has not occurred, create a new APN manually. type the name (any), APN (gateway address, for example, Internet.mms.ru) and save the settings. After saving, be sure to select the created access point, mark next to it, and restart the phone.
Optimizing work and saving energy
MIUI is known for its aggressive energy saving policy, which can shut down the background processes of the message application, which causes notifications of new SMS to arrive with a delay or not at all. To avoid this, you need to configure the application in the background. This is especially true for the Xiaomi Mi 10 Pro, where battery optimization is the first place.
Go to Settings → Applications → All apps, find your SMS application. Select AutoStart and turn it on. Then go to Battery (or Energy Saving) and select No Limits mode. This will prevent the system from "killing" the message process when the screen is off.
💡
The “No Limits” mode for the messaging app is critical to getting confirmation codes and important notifications on Xiaomi smartphones in a timely manner.
It is also worth checking the notification settings.
- 🔔 Make sure that “Sound Notifications” and “Pop-up Notifications” are enabled".
- 🚫 Check if the "Do Not Disturb" mode is worth the schedule.
- 🔒 In the Security app, make sure the app is not blocked.
⚠️ Warning: No Limits settings may slightly increase battery consumption, as the app will be constantly active in the background.
For maximum efficiency, it is also recommended to disable the in-app transition animation if you are using an older version of MIUI that can slow down. In newer versions of the shell, the Xiaomi Mi 10 Pro runs quite smoothly, and additional optimization is rarely required, except for the installation of heavy third-party themes.
