Owners of budget smartphones often face a situation where after installing a new SIM-card access to the network is not available, although other subscribers of the same operator everything is stable. Xiaomi Redmi 9 is no exception, and its operating system MIUI sometimes requires manual adjustment of parameters to correctly display 4G. The lack of Internet can be caused by a failure in the profile of the APN access point or banal frequency incompatibility.

In this article, we will discuss in detail the algorithm of actions that will help to return the mobile Internet to working condition without contacting the service center. You will learn not only to activate data transfer, but also to correctly prescribe the settings for any Russian and foreign telecom operators.

The right network configuration is the key to fast loading pages and stable operation of messengers. Ignoring basic parameters can lead to the fact that the phone will only work in 2G mode, which in modern conditions is almost unusable.

Checking physical factors and condition SIM-map

Before you go into software settings, you need to rule out the trivial physical reasons for the lack of communication. Often the problem lies in oxidized contacts or improperly installing the card in the tray. Make sure that the card chip fits tightly into the contacts inside the slot.

Notice the condition of the card itself, which, if it's been in use for a long time, could cause scratches or scuffs in the contact area, and even a serviceable Redmi 9 smartphone can't read the operator's data correctly.

• 📱 Check if your carrier is active (sometimes the balance goes into the red).
• 🔌 Remove the tray and wipe the contacts SIM-soft-cloth.

Basic activation of mobile data in the MIUI interface

The MIUI shell interface has its own features that can confuse the inexperienced user. Unlike pure Android, traffic management is put into a separate security menu, but the basic switches are in the notification curtain.

Manually configuring the APN access point

The most common reason for the lack of internet is the incorrect APN (Access Point Name) setting, which is the address the phone accesses the carrier gateway. In Redmi 9, these settings often come automatically, but sometimes they need to be manually spelled out.

Example of settings for MTS:


Name: MTS Internet




APN: internet.mts.ru




Login: mts




Password: mts

Once you have entered, be sure to click on the three dots in the corner of the screen (or menu button) and select Save. Then go back to the list of access points and activate the profile you created by putting a dot next to it.
