Have you sent an important message and the recipient on Xiaomi never received it? Or can not accept SMS from the bank, services or friends? The problem with delivering messages on Redmi, POCO or Mi smartphones is more common than you think - and both phone settings and external factors can be to blame. In this article, we will discuss all possible reasons why Xiaomi does not accept SMS, from the banal lack of a network to hidden bugs of MIUI firmware.
The peculiarity of Xiaomi devices is that they often face conflicts between the standard Messages application and Google services (for example, Google Messages), and also have unique settings for working with the company. SIM-Also, after the updates, MIUI Network settings are often reset, resulting in loss of communication with message service centers (SMSC). Not only will we list the symptoms, but we will also give step-by-step instructions with illustrations (where this is critical), and we will also warn against common mistakes that users make when trying to fix the problem.
If you're in a hurry, use the FAQ box at the end of the article, which contains answers to the most common questions.
1.Problems with SIM-card-carrier
The first thing to check is the physical condition. SIM-And even if the phone is showing the signal on the network, it doesn't guarantee that the text is working properly:

- π Malfunction SIM-Cards or slots: Try inserting another SIM-If it doesn't work, it's the phone.
- π₯οΈ Modem firmware failure: This is a rare but possible case, especially after unofficial firmware (custom) ROM).
To diagnose hardware problems:
- Check the phone's IMEI (enter *#06#). If it shows as 000000000000000, the modem firmware has gone off.
- Install the DevCheck app and check the status of the Cellular module.
- If you suspect an antenna damage, contact a service center. Self-repairing can exacerbate the problem.
β οΈ Note: Xiaomi with MediaTek processors (e.g. Redmi Note 11 or POCO M4 Pro) modem crashes are more common than on Qualcomm Snapdragon. If the network is lost after firmware, try reflashing the phone with the official version MIUI via Fastboot.
7. Features of working with eSIM and virtual operators
If you use an eSIM or a virtual carrier (e.g. Tinkoff Mobile, SberMobail), the problem may be due to incorrect profile activation or operator restrictions.
