How to turn on 4G on Xiaomi: The Complete Guide

Modern smartphones Xiaomi, Redmi and POCO support high-speed data transmission standards, but sometimes users are faced with a situation where the device automatically switches to 3G or even EDGE. This can occur for a variety of reasons: from the settings of the device itself to problems on the operator’s side. The speed of mobile Internet directly affects the comfort of using navigation, streaming services and video, so the issue of activating 4G LTE is a priority.

In this article, we will explore all possible ways to force the fourth generation of communication, you will learn where hidden engineering menus hide, how to correctly prioritize the network and what to do if the icon is missing. LTE Often the solution lies in simply reconfiguring the access point or replacing it. SIM-maps for more modern.

Before you go to complex manipulations, you need to make sure that your equipment is compatible with the basics. Not all models, even those released relatively recently, have the same communication modules for different regions. In addition, the tariff plan should provide access to high-speed Internet, as some carriers by default block LTE at old tariffs.

Reviewing the support of standards and SIM-map

The first step should always be to diagnose the hardware. 4G simply because the established SIM-The card is too old and does not support the standard. USIM. Communications operators are gradually withdrawing old-style cards from circulation, replacing them with new chips with support for encryption and high speeds.

Global versions of Xiaomi smartphones (Global ROM) usually have a full range of frequencies, while the Chinese versions (CN ROM) may not support some LTE bands used in Europe or the CIS.

⚠️ Attention: If yours SIM-The card was hand-cut from the Mini or Micro format to Nano, which could damage the contacts or chip, in which case even the new phone would not be able to catch a stable signal. 4G.

An engineering menu can be used to quickly check the type of map and network status, but first make sure the service is available. 4G It's activated on the operator side, and often it's enough to just call support or send it to the operator. USSD-request that the tariff be updated remotely.

• 📱 Make sure that SIM-card 5-7 It has a Nano-SIM format without mechanical damage.
• 🌍 Check the phone model for support for the bands (Band 3, 7, 20, 38) used by your carrier.
• 💳 Contact the operator to clarify the status of the service connection LTE/4G on your room.

If the card and the fare are all right, we move to software settings, and sometimes the system itself limits the speed to save battery power, especially in energy saving mode.

Basic settings through the smartphone menu

The standard MIUI or HyperOS shell interface provides easy access to network connectivity management, and it is often enough to simply change the preferred network type in the appropriate section, but the location of these settings may vary depending on the operating system version.

To find the desired parameters, go to Settings, then select the item SIM-You have to choose an active SIM card, if there are two, and find the Network Type section. LTE or 4G (recommended).

In some cases, after selecting the right item, the phone may need to restart, which is normal, since the communication module needs to re-register with new parameters, and do not ignore this step if the changes do not take effect immediately.

Note the Use 4G switch, which in older versions of MIUI could be displayed separately, and if you see a switch like this, it must be activated, and the absence of this switch in newer versions means that the system automatically controls this setting based on the type of network you choose.

Using the Engineering Menu for Forced 4G

If standard settings fail, you can use Android’s hidden engineering menu, which allows you to force the radio module to switch to LTE mode only, ignoring 2G and 3G signals. This is especially useful in areas of uncertain reception, where the phone constantly “jumps” between standards, losing connection.

To enter the menu, dial the Phone app code ##4636##. If the code works, the Check menu will open. Select Phone Information. In the list that opens, find the drop-down menu Set Preferred Network Type.

Select the LTE Only option. After that, the 4G icon should appear in the status bar. However, be careful: in this mode, incoming voice calls may not pass if your carrier does not support VoLTE technology or if you are outside of 4G coverage.

To return to normal mode, simply select NR/LTE/GSM/WCDMA from the same menu or restart the device. Remember that running continuously in LTE Only mode can consume battery power faster, as the phone will try to communicate with the tower even at very weak signal, without switching to more stable 3G.

Setting up APN access points

Often the problem with not having 4G is that the APN is the address that the phone uses to access the carrier's gateway to access the Internet, and if that data is lost or missing, the high-speed connection will not be established, even if the network signal is excellent.

Settings APN are on the way: Settings → SIM-maps and mobile networks → Settings APN. Click on your carrier name or create a new access point if the list is empty, APN, type of authorization) can be found on the official website of your operator.

It is critical to correctly specify the type of APN. To work 4G, the default,supl or just default box must be written in the APN Type field. The letter register matters, so it is better to copy the values from the operator's website or reset the settings to factory values for your region.

• 📡 Name (Name): Any, for example, MTS Internet.
• 🌐 Access point (APN): Strictly according to the operator (for example, Internet.mts.ru).
• 🔑 Type of authorization: Usually PAP or CHAP (It is indicated on the operator's website).
• ✅ Type APN: It must contain the word default.

After making changes, remember to save the profile by clicking on three dots in the corner of the screen and selecting Save, then activate it with a tick.Reboot the phone will seal the result.

💡

If you changed your APN settings but the internet didn't come up, try turning on your flight mode for 10 seconds and then turning it off, and this will force the device to re-register with the new settings.

Network reset and system errors

Sometimes software failures accumulate in the system, interfering with the correct operation of communication modules, updating the firmware, installing dubious applications or changing system files can lead to conflicts, in such a situation, the solution is to reset the network settings.

This operation will not delete your personal data, photos or contacts. It will return only the parameters of Wi-Fi, Bluetooth and mobile networks to factory values. To do this, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.

⚠️ Note: After resetting your network settings, you will have to re-enter passwords from all saved Wi-Fi networks and re-match Bluetooth devices such as watches or headphones.

If that didn’t work, check for system updates. Xiaomi regularly releases security patches and improvements for modems. Go to Settings → About phone and click on MIUI/HyperOS. Also check for updates in the Security and Google Play Services app.

In rare cases, the problem may be related to physical damage to the antenna or plume, especially if the phone has recently fallen. SIM-card 4G It may be possible to have a diagnosis at the service center.

The impact of two SIM-mapping the speed of the Internet

Owners of two-symbol Xiaomi smartphones should be aware of the important feature of the modem. DSDS (Dual SIM Dual Standby) in full, with activation of the second SIM-The speed of the first card may be limited, or the second card will work only in the mode. 2G.

Modern processors allow both slots to work in 4G, But there's only one active to transmit data. If you notice a speed drop, try to extract a second one. SIM-If it grows, it means the limitation is due to the design of your device.

Also make sure that the correct setting is selected. SIM-Data card. Path: Settings → SIM-maps and mobile networks → Internet. Make sure that there is a SIM card with a connected tariff. 4G, Not the one that is used only for calls.

In addition, some operators require registration. IMEI network-worker 4G, It's rare in the CIS, though, if you've moved it. SIM-card to a new phone and 4G Missing, wait. 15-30 minutes or restart the device to the network to update the data.
