How to turn on mobile Internet Xiaomi Redmi 9

A modern smartphone like the Xiaomi Redmi 9 is almost impossible to imagine without constant access to the world wide web: mobile Internet allows you to stay connected, navigators build routes in real time, and streaming services give endless entertainment. However, it often happens that after buying a new device or changing the device. SIM-card automatic setting does not occur, and the user remains at the screen with the dead data indicators.

Owners of the budget segment to which this model belongs sometimes face the need to manually adjust network parameters. This can be due to the features of the tariff plan, the specifics of the local coverage or simply a failure in the software of the MIUI shell. In this article, we will discuss in detail how to activate and configure data transfer to make your gadget work at full capacity.

Do not panic if after installing the SIM card icon “E», «3G» or «4G» Android requires certain permissions and the right access points to connect properly to the operator's gateways, and we'll look at everything from the simple actuation of the slider in the curtain to the deep tuning. APN-profile.

Basic activation of data transfer via the settings menu

The most obvious and common way to get the internet up and running is to use the standard operating system interface. In Xiaomi smartphones, network management is put into a separate block where all the key switches are concentrated, and you need to unlock the screen and find the Settings icon, which usually looks like a gear.

Once you enter the menu, you'll find the wireless connection section. MIUI It may be called differently, but most often it is a paragraph. SIM-And that's where the voice and packet controls are, and make sure you pick the SIM card that has the Internet connection, if you have two.

Inside the menu, select the slot you want (SIM 1 or SIM 2) and you will see a list of settings where you first need to activate the Mobile Internet switch, it should light up in blue, which signals that the device is trying to register with the operator's network. If the slider is already active, but there is no Internet, try turning it off and turn it on again after 10 seconds.

It is worth noting that in some regions or when using certain operators, additional authorization may be required.The system may request confirmation of actions or warn of possible traffic consumption. MIUI often suggests enabling traffic savings, which is useful for controlling costs, but may limit the background activity of applications.

Use of the Quick Access Panel (Stork)

For those who value time and prefer to minimize the number of clicks on the menu, there is a faster method. The notification and quick access panel in Redmi 9 contains shortcuts for the most important functions. To get there, you need to swipe from top to bottom of the screen. Depending on the interface settings, you may need one or two swipes to reveal the full list of icons.

Among the many colored boxes, find an icon that is signed as Mobile Internet or has a carrier logo, and clicking on it instantly activates or deactivates data transmission, which is especially useful when you need to urgently check your mail or card without diving into the wilds of system settings. Visual indication in the status bar (top of the screen) immediately shows the result of your actions.

If you don't see the right shortcut on the first page of the panel, swipe left or click the edit button (usually a pencil or three dot icon). In the editing menu, you can drag the Mobile Data icon to the active area for quick access in the future, which allows you to personalize your workspace to your habits.

Sometimes, when you press a button, nothing happens in the curtain, and then the system can be temporarily overwhelmed by background processes, try to close the extra apps or just restart the smartphone, which is a classic technique that solves 90% of software glitches.

💡

If the mobile internet icon is missing from the curtain, check whether Do Not Disturb or Save Energy is enabled, as they can block network shortcuts.

Configure APN access points for different operators

The most common reason for the lack of Internet when a switch is running is the incorrect configuration of access points. APN. These are the gateway addresses through which your device connects to a particular provider's network. In Xiaomi Redmi 9, these settings usually come automatically from the same location. SMS-A message from the operator, but sometimes they have to be manually written.

To get to this section, go to Settings path. → SIM-maps and mobile networks → (Select a SIM card) → Access points (APN). Here you will see a list of existing profiles. If the list is empty or the current profile is not working, click the button. + or a new access point at the bottom or top of the screen.

The key fields are Name (anything like MTS Internet) and APN (Access Point Address). The other fields, such as username and password, are often left blank or filled in according to the operator's specification. Below is a table with the main parameters for popular carriers.

Once you have entered all the data, make sure to click the menu (three dots) and select Save. Then go back to the list of access points and check the box against the created profile. Without saving and actively selecting, the new configuration will not take effect. Rebooting the device after this procedure will help to fix the changes.

Selection of network type and preferred mode

Modern networks offer different communication standards, from outdated 2G to high-speed 4G and experimental 5G. For comfortable use of Redmi 9, it is important to choose the optimal mode. In the Preferred Network Type menu (located in the same place as the APN settings), you can manage priorities.

It is recommended to set the 4G or LTE Preference value.This will provide top speed where coverage is available and automatic 3G rollback in places with poor signal. Choosing 4G Only mode can result in a complete loss of communication if you are in an area where LTE is not already deployed, so it is better to leave the switching option.

If you're in a hot spot, the phone can jump between standards all the time, which puts the battery down quickly, and in those cases, it makes sense to force a 3G or 2G switch for connectivity stability, albeit at a slower rate, which is true for messaging calls on country roads.

Also in this section, the option to Use LTE is often found. Make sure it's activated. Some carriers require VoLTE for sound quality, and this option is responsible for voice transmission over fourth-generation networks. On Redmi 9, this feature works consistently with most large providers.

Solving definition problems SIM-map

There are times when the phone just doesn't see the SIM card. The screen can show the message "No." SIM-It's worth doing a series of self-checks before you bring a device to the service, and often the problem is a physical contact or software freeze of the communication module.

First, remove the SIM card tray with a special paper clip. Carefully examine the golden contacts on and inside the card. The presence of dust, oxides or mechanical damage can interfere with reading. Wipe the SIM card contacts with a soft dry cloth and gently insert back, making sure that it sat tightly and smoothly.

If a physical check doesn't work, try moving the SIM card to the second slot, which will help you understand if the problem is in the particular connector or in the card itself, and it's also useful to check the SIM card on another phone, and if there's no network, then the card is defective or blocked by the operator, and you need to contact the communication salon.

⚠️ Warning: Never try to insert or remove SIM-card while the phone is on, unless the settings include "Hot Replacement." Although modern smartphones support Hot-swap, it is safer to manipulate the tray on the device off to avoid short circuits.

In the software part, it is worth checking whether it is blocked. SIM-The map is in the settings. SIM-If you have a switch on the card and mobile network, you have to have a switch on the switch on the right slot, and if you have a "Switch off" on the card, the phone ignores the card, even if it's physically inside.

Resetting network settings and additional recommendations

When all of these methods fail, the radical but effective step is to reset your network settings, which will bring all of your Wi-Fi, Bluetooth and mobile settings back to factory values, and your personal files, photos and contacts will not be affected.

You can reset via Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm the action, then the phone will restart. You will have to re-enter passwords from Wi-Fi networks and reconfigure APN access points, but often this completely solves the problem with the modem "glitch".

Another important aspect is the system update. Xiaomi regularly releases security patches and improvements for MIUI. Go to Settings → About the phone and check for updates. Sometimes network bugs are fixed in new versions of the firmware.

💡

Network reset is a secure procedure that eliminates software conflicts in the communication module, but requires re-authentication in Wi-Fi networks.
