How to enable mobile Internet on Xiaomi: from settings to hidden menus

Modern Xiaomi and Redmi smartphones have become indispensable satellites in the digital world, where access to the network is necessary every minute. SIM-map or system update icon 4G or+ This can be caused by a simple error in the menu, and deeper system failures that require interference with the parameters of the access point. In this article, we will discuss all the stages of activation of data transfer, from basic switches to manual registration. APN-parameters.

Before we get to the tricky stuff, it's worth checking out the obvious things that are often overlooked. Sometimes the problem isn't the software, but the physical contact of the SIM card or the temporary failure of the radio module. Mobile Internet on MIUI and HyperOS devices is governed by a complex system of priorities that can conflict with the operator's settings. So if you see crossed-out arrows or an "G" icon instead of the expected "LTE", you don't panic - in 90% of cases, you can fix the situation yourself in a few minutes, following a logical algorithm of actions.

Special attention should be paid to the correct operation of the radio module, because it is responsible for receiving the signal of the cell tower. If there are coverage outages in your region or there are preventive work carried out by the operator, no settings of the phone will make the Internet work faster. However, if the neighbors with phones of the same operator are functioning normally, then the reason lies in the configuration of your Xiaomi. Next, we will look at the step-by-step process of diagnosing and enabling high-speed connection.

Basic activation through the curtain and settings menu

The fastest way to start data transfer is to use the notification panel, but in the MIUI shell this control can sometimes hide additional options. The standard procedure involves swiping from top to bottom to open the "curtain" where the "Mobile Internet" or "Data Transfer" button is located. If the icon does not light up in green or blue after pressing, and the system gives a notification about the lack of access, you need to go to the deep settings menu for detailed verification.

To do this, open the Settings app and select a section. SIM-Maps and mobile networks. This menu displays all active SIM cards, and it's important to make sure that the "Enable Mobile Internet" switch is activated for the card you're planning to access. Often users forget that on dual-symbol devices, the priority of the Internet and voice calls can be spread across different slots, which creates confusion.

⚠️ Note: If the mobile Internet switch is active in the settings but the icon does not appear in the status bar, try rebooting the device. Xiaomi radio can hang in the background, and a simple reboot often resets this software stupor.

In the same settings section, it is useful to check whether the Traffic Saving mode is turned on, which can block background applications and create the illusion of a network absence. Also, you should pay attention to the item "Use mobile Internet", where you forcibly select a SIM card to access the network if you have two active cards installed. The priority SIM card must be chosen correctly, otherwise the phone will try to download data through the card with zero balance or without a tariff.

Setting up an APN access point for different operators

If basic settings are enabled but the internet is not working, it is likely that the phone is missing or misdefined with the APN (Access Point Name) access point settings. This is the gateway through which your device connects to the carrier gateway. On modern Xiaomi smartphones, this data is usually downloaded automatically when you first install the SIM card, but manual network selection or corporate tariffs may require user intervention.

To check or change these settings, go to Settings. → SIM-maps and mobile networks → Choose your SIM card → Access points (APN). In the list that opens, you'll see the current profile. If the list is empty or the Internet is not working, click the "New Access Point" button or the plus icon in the corner of the screen.

For most Russian operators, the settings are as follows, and can be entered manually if the automatic setting does not work:

• 📡 MTS: Name: mts internet, APN — Internet.mts.ru, login and password - mts.
• 📡 Beeline: Name: Beeline Internet, APN — Internet.beeline.ru, login and password - beeline.
• 📡 Megafon: Name of Megafon Internet, APN — Internet, login and password - gdata.
• 📡 Tele2: Name — Tele2 Internet, APN — internet.tele2.ru, login and password are left blank.

Once you have entered all the options, be sure to click the menu (three dots or the "More" button) and select "Save." Then go back to the previous menu and make sure that the tick is exactly opposite the created or edited profile. Sometimes the Android system requires you to re-enable flight mode to apply new network settings.

Selection of network type and preference mode

A critical stage in the diagnosis is to check the mode of operation of the network. Xiaomi smartphones support many communication standards, from ancient 2G to modern 5G. If the settings are forced to set the mode "Only 2G" or "Only 3G", the phone will not be able to connect to the 4G towers, even if they are in the immediate vicinity, this often happens after resetting or when traveling to other regions.

To change the mode, go to Settings → SIM-maps and mobile networks → select a SIM card → Network type (or "Preferred Network type"). You must select "Preferred" option here. LTE" or "5G/LTE/3G/2G (This setting gives the telephone permission to search for the highest possible connection speed available in the area.

There is also a hidden engineering menu that allows you to control the radio module in more detail, but for the average user, standard settings are enough. If even when choosing "preferably LTE" the phone stubbornly holds 3G (H+), try temporarily turning on flight mode for 10-15 seconds, and then turn it off, this will force the modem to re-register on the network and possibly choose a more optimal base station.

⚠️ Note: Compulsory inclusion only 4G (LTE Only) through the engineering menu may result in a complete loss of communication if there is no coverage in your area. LTE, As the phone will not be able to switch to 3G for voice calls (if not configured with VoLTE).

Resetting network settings and radio module

When software failures accumulate, standard flight on/off may not help. Network settings reset is effective in such cases. It is important to understand that this operation will not delete your personal files, contacts or applications, but it will clear all stored Wi-Fi and Bluetooth pairing passwords, as they relate to network settings.

You can reset through the Settings menu → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth → Reset. Once confirmed, the phone will reboot the network modules, an action that often resolves problems when the phone "sees" the network but cannot log in or get access to it. IP-operator.

An alternative, more radical method is the use of USSD-In the call app, dial ##4636##. The Testing menu will open where you select Phone Information. This menu has a button to “Run Ping Test” or the ability to temporarily change the type of network, which also causes the radio stack to restart.

Problems with SIM-map and physical contact

Often the reason for the lack of Internet is trivial – poor contact of the SIM card with the contacts of the tray. Over time, metal can oxidize on the gold contacts of the card or accumulate dust, which prevents normal data exchange with the operator, especially for older SIM cards that have been used for years and have been cropped as nano-SIM.

It is recommended to remove the tray, gently wipe the SIM card contacts with a soft dry cloth or a stain (very carefully). If the SIM card is very old (released more than 5-7 years ago), it makes sense to contact the operator's salon for a free replacement with a new one with support for modern encryption standards and 4G/5G. Old cards may simply not work properly in modern Xiaomi networks.

It is also worth checking the integrity of the tray itself. If it is deformed or skewed, the SIM card may not fit tightly. In dual-symbol phones, try moving the card to another slot (SIM 1 or SIM 2), as sometimes one of the slots may have a software or hardware defect.

• 🔍 Examine the SIM card chip for scratches or chips.
• 🔍 Make sure the card is inserted into the tray by the correct side (in the shape of the cutout).
• 🔍 Check if the tray sits tightly in the phone case after installation.

Impact of MIUI and HyperOS Updates on the Network

Xiaomi users are well aware that system updates (MIUI or new HyperOS) can bring not only new features, but also network bugs. After a major firmware update, network profiles are often lost or the algorithms for working with base stations change. If the Internet disappears immediately after the update, there is a high probability of a software conflict.

In such cases, it is worth checking for updates for Google Play Services components and system applications, as they are responsible for basic communication functionality. You can also try to clear the cache of the Settings and Phone application, although this is less effective than a complete network reset. Sometimes waiting helps: after a major update, carriers can update their network settings remotely, and after 24-48 hours the problem resolves itself.

💡

If the Internet is unstable after updating the firmware, try temporarily disabling the Wi-Fi Assistant function in the Wi-Fi settings. It can mistakenly switch traffic to the mobile network even if Wi-Fi is working normally, or vice versa, block mobile Internet when the router signal is weak.
