How to turn on the Internet on Xiaomi: step-by-step instructions

Modern smartphones Xiaomi and Redmi are powerful multimedia centers, whose work is unthinkable without a permanent connection to the global network. SIM-Mobile Internet stops working automatically, this can be caused by a failure of settings, the absence of an activated service from the provider or a software conflict in the shell. MIUI. Understanding the basic principles of network modules will allow you to quickly troubleshoot problems.

In this article, we will discuss in detail all possible ways to activate data transmission, starting from the banal inclusion of the slider in the curtain and ending with manual registration of the parameters of the access point. APN. It is important to consider that the interfaces of different versions of firmware may differ slightly, but the logic of actions remains the same for the entire ecosystem of the brand. SIM-maps and specific settings for 4G/LTE network.

Before you start complex manipulations, make sure your SIM-The card is active and there are funds on the balance sheet. Sometimes the problem is not the phone, but the lack of network coverage in a particular location or the temporary work of the operator. If you are sure that the card and the coverage are all right, then move to the software configuration of the device.

Quick activation through the notification curtain

The easiest and most common way to start data transfer is to use a quick access panel, which is suitable for everyday use when you need to quickly switch from Wi-Fi to mobile traffic, and owners of Redmi and Poco smartphones can control this process in a single touch without diving into the depths of the menu.

To do this, you need to unlock the screen and swipe from the top edge of the display down to open the control center. Find an icon signed as "Mobile Internet" or "Data Transfer", which usually looks like two arrows pointing up and down. Click on it to activate the function: the icon should be illuminated in blue or green, which signals a successful start of the process.

Some versions of the MIUI shell have SIM management on a separate menu, so if you just click it, you can hold that icon for a few seconds, and you can select the SIM card to go online if you have two, and you can see the current traffic flow and go to more detailed settings.

• 📱 Swipe from top to bottom to open the control center.
• 🔵 Find the Mobile Internet icon (two arrows).
• ⚡ Click once to turn on or long to select SIM.
• 📶 Make sure the network indicator in the status bar shows 4G or LTE.

It's worth noting that when you activate the mobile Internet, the system can request permission to use geolocation to better determine the location, which is a standard procedure that helps you find the nearest cell towers faster. If you turn on the icon, but the pages in the browser do not load, try to switch flight mode.

💡

If the internet doesn't work immediately after you turn it on, activate Flight Mode for 10 seconds, and then turn it off, which will force the phone to re-register in the operator's network.

Configuring data transfer in the system menu

If your desktop widgets don't work or you need a more fine-tuning, you should consult the system menu. This is where all the key switches that are responsible for your Xiaomi's network activity are located. This section allows you not only to turn on the Internet, but also to adjust restrictions to save traffic.

Go to the Settings section, select the item «SIM-This is where the main switch is located, which is often hidden from the user's eyes in standard mode. In the window that opens, find the "Mobile Internet" or "Use Mobile Internet" switch and put it into the active position. Without this step, even the presence of a SIM card will not give access to the network.

You can also set the priority menu. SIM-The system allows you to flexibly manage the flow: you can set limits, turn on warnings about exceeding the volume or even prohibit background data transmission to save battery power. These settings are critical for GB limited package tariffs.

Note the "Network Type" option: For maximum speed, it is recommended to choose LTE or 5G mode, if your tariff and carrier coverage support this, and if the signal in your area is unstable, sometimes it makes sense to forcefully switch to 3G to provide at least slow, but stable access to messengers.

⚠️ Warning: Do not enable data roaming if you are in your home region, which can result in large amounts of money being written off from your account, even if you have not been outside the country, but your phone has connected to an affiliate network.

Manually configuring the APN access point

Often times, the SIM card is identified, there is money in the account, but the Internet does not work. In 90% of cases, the problem lies in the absence or incorrect settings of the APN access point, which is a kind of "key" that allows the phone to correctly connect to the operator's gateway to access the world wide web.

To check or create a new access point, go to Settings → SIM-maps and mobile networks → select the desired SIM card → Access points (APN). If the list is empty or the current point is not working, click on the New Access Point or Reset to default settings.Reset often solves the problem by automatically pulling the correct settings from the operator's server.

If you don't automatically set up, you'll have to enter the settings manually, and you can find this information on your mobile operator's official website, and you'll usually need to fill in the Name and APN fields, and you can leave the remaining fields unchanged or empty. After you enter, make sure you save your profile and select it active.

After saving the settings, it is recommended to restart the device, which is necessary to ensure that the network module fully reconnects with the new parameters. If after the reboot, the 4G or H+ icon appears but the pages do not open, check whether the APN settings have a proxy server or port that your operator does not require.

Using two SIM-mapping

Xiaomi smartphone owners often use two numbers at once: one for work, the other for personal use. The system allows you to flexibly manage which of the SIM cards will be used for data transfer, while the second can be occupied by voice calling.

On the menu. SIM-There's a default section for maps and mobile networks, and you can assign a call card here, SMS It's important to understand that the Internet will only work on the SIM card that you select from the Internet, and switching between them is instantaneous, but requires confirmation in some firmware versions.

There is a function of “Intellectual Choice”. SIM-maps that try to determine which map is best for the current location, but for stable operation, it is better to set a strict priority. If you use the tariff with unlimited Internet on one card, make sure that it is active in the data transmission settings, so as not to waste paid traffic of the second card.

• 🔄 Go to the settings. SIM-priority management maps.
• 📞 Set up a primary. SIM for calls and separate for the Internet.
• 🚫 Turn off the second. SIM, If not used, it will save energy.
• ⚙️ Make sure that roaming is not included on both cards at the same time.

It is worth remembering that when you are actively calling on a card that is not selected for the Internet, the connection to the network can be temporarily interrupted or switched to EDGE if VoLTE technology is not supported. For smooth operation, it is desirable that both SIM cards support 4G, and VoLTE mode is enabled in the settings.

Solving Connectivity Problems with 4G and LTE

Even with a supported tariff and SIM card, the phone can stubbornly cling to 3G or E. This may be due to the network type preferences or the frequency features your Xiaomi catches in a given area. Global versions of smartphones sometimes do not support all the frequencies of local carriers (for example, Band 7 or Band 20).

You can check if your model supports the required frequencies on specialized sites, knowing the exact model of the device. → The phone. → Click on "Version" several times MIUI», To open the engineering menu (if available), or use hidden code ##4636##. From the menu that opens, select Phone Information and find "Install preferred network type».

You can choose LTE Only or LTE/TD-SCDMA/GSM. Be careful: LTE Only can cause you to stop receiving incoming calls if the operator does not support VoLTE technology.

⚠️ Note: Change of parameters in the engineering menu (##4636##) It could cause you to lose all communication («LTE/TD-SCDMA/GSM (auto mode) after verification.

Also the cause of problems with 4G maybe old SIM-If your SIMKA is bigger than yours 5-7 It may not be physically up to the standards. 4G. In this case, only the replacement of the card in the operator’s cabin will help, the number is usually saved.

💡

Problems with 4G Often replaced by the old SIM-maps to new or reset network settings to factory parameters.

Resetting network settings as a radical solution

If none of the above methods worked, and the Internet on Xiaomi never worked, it may have accumulated software errors or profile conflicts, in which case the way is a complete reset of network settings. Importantly, this action will not delete your personal files, photos or contacts, but will forget all saved Wi-Fi passwords and Bluetooth settings.

To perform this operation, go to Settings → Connection and Sharing (or “Advanced Settings”) → Reset Wi-Fi, mobile networks and Bluetooth. Click Reset button at the bottom of the screen. The system will ask you to confirm the action with an unlock code or a pattern lock.

Once the process is complete, the phone will restart, and you will need to re-enter the Wi-Fi passwords and possibly reconfigure the APN hotspot, although most of the time the correct settings are automatically tightened immediately after the reboot, a method that helps in most cases when a software failure blocks the modem.

• 📂 Go to the section "Connection and Sharing».
• 🗑️ Select “Reset Wi-Fi, Mobile Networks and Bluetooth».
• 🔐 Confirm the action with a password from the lock screen.
• 🔄 Wait for the reboot and check the Internet.

In rare cases, even when the reset doesn't work, the problem may be in the hardware, the antenna module or the board itself. If the phone falls or falls into the water, the likelihood of hardware failure increases, in which case acting alone can be dangerous, and it is better to contact an authorized service center.
