Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the status bar instead of the expected high-speed indicator is in the status bar. 4G or+ displays standard E (EDGE) Or, in rare cases, just G. This means that the device is running an outdated data standard, making watching video or navigating virtually impossible. MIUI HyperOS or in the limitations of the mobile operator.
To solve this problem, the user needs to consistently check several configuration levels: from the basic settings of the access point to hidden engineering menus, access to which requires the input of special configurations. USSD-It's important to understand that the H mode (HSPA) is an intermediate stage between 3G full-fledged 4G, And it may be required to be forced to turn on in areas of uncertain reception, where the phone constantly "jumps" between standards, draining the battery.
In this article, we will discuss in detail the algorithm of actions to transfer a smartphone to the preferred mode of using high-speed batch data. We will touch on the issues of setting up APN, working with SIM cards of different operators and using Android diagnostic tools to fix network priority.
Basic network type setting in the smartphone menu
The first and most obvious step is to check the standard mobile network settings. MIUI The path to these options may vary slightly depending on the Android version, but the logic remains the same. SIM-Maps and mobile networks and choose an active SIM card.
In the menu that opens, find Network Type or Network Preferred, and here the system will offer several options, among which should be present Preferably LTE or 4G/3G/2G (auto), which allows the phone to choose the best available signal, prioritizing high-speed connections.
⚠️ Note: If there is no option in the list of available network types 4G or LTE, This may indicate that the SIM card is too old and does not support higher standards. 3G, Your service plan does not include high-speed internet packages.
Sometimes manual brute force helps, so try to select 3G Only, wait for the H or H+ icon to appear, and then return the setting to automatic mode, a method that often forces the modem to re-register and pick up a faster protocol.
💡
Before changing your network settings, be sure to turn on and off the Reim Flight in the notification curtain, which will force the communication module to the nearest tower with the updated settings.
Configuration of the APN access point for acceleration
If the choice of network type failed, the problem may be hidden in the incorrect settings of the APN (Access Point Name) access point, which is a gateway between the operator’s network and the Internet. Often the automatic settings that come to the SMS may be incorrect or outdated for the current location.
For manual check, go down the Settings path → SIM-maps and mobile networks → select a SIM card → Access points (APN). In the upper right corner, click the menu button or plus icon to create a new point. It is critical to fill in the Name and Plus fields correctly. APN.
- 📡 For MTS operator in the field APN You need to register Internet.mts.ru.
- 📡 For MegaFon, the Internet is used.
- 📡 For Beeline, you should specify Internet.beeline.ru.
- 📡 For Tele2 Yota also uses the universal meaning of the Internet.
Once you have entered, be sure to save your profile by clicking the corresponding button in the menu and activate it with a switch. It is not superfluous to delete old, unused access points to avoid priority conflicts when connecting.
☑️ Checking settings APN
Using an engineering menu to fix the mode
The most effective, but careful, method is to use the Android hidden engineering menu, which allows you to interact directly with the device's radio module, bypassing standard interface restrictions.
For most Xiaomi devices with MediaTek and Qualcomm processors, codes ##4636## or ##3646633## are running. Once you enter the last character, the menu will open automatically.
Inside, find the drop-down list Set Preferred Network Type. This list presents a wide range of combinations. To enable H mode (HSPA) as a priority, but with the ability to work in 4G, you should choose LTE/TD-SCDMA/GSM or LTE/WCDMA/GSM. If you want to force switch only to 3G/H, choose WCDMA only.
⚠️ Warning: Changing the parameters in the engineering menu can lead to complete signal loss or incorrect operation of the communication module.
Once you select the right option, click the Apply button. The signal in the status bar should disappear for a few seconds and reappear with the new designation. If you choose LTE only, and there is no 4G in the reception area, the connection will disappear completely — that's normal.
What if the code doesn't work?
Comparison of communication standards: G, E, 3G, H, 4G
Understanding the difference between the icons displayed helps diagnose the problem. Each letter denotes a particular data technology and its maximum theoretical speed. Below is a table showing the evolution of standards.
| Designation | Technology | Max. Speed (theor) | Status |
|---|---|---|---|
| G | GPRS (2G) | up to 115 kbps | Obsolete. |
| E | EDGE (2.5G) | up to 473 Kbps | Basic |
| 3G | UMTS | up to 2 Mbps | Standard. |
| H / H+ | HSPA / HSPA+ | up to 42 Mbps | High speed. |
| 4G | LTE | up to 300 Mbps | Priority. |
H+ mode is often called “3.5G.” It is significantly faster than regular 3G and in many use cases (navigator, messengers, music) is almost equal to the initial 4G. If your phone is “stuck” on E, but you are in the city, this is a clear sign of a software error or missetting priorities.
💡
The H+ icon provides sufficient speed for most everyday tasks, even if full 4G is temporarily unavailable or unstable.
Problems with SIM card and operator
Often the reason you can’t turn on H or 4G is because of the physical condition of your SIM card, and if you use a SIM card that’s been released for more than 5-7 years, it can be cut manually or simply have an old chip that doesn’t support modern 3G/4G authentication protocols.
In this case, no settings on Xiaomi's phone will help, and the only solution is to replace the SIM card in the carrier's cabin, which is a free procedure that takes a few minutes, after which you get a new chip that supports all the current communication standards.
In some remote areas or inside buildings with thick walls, the 4G signal may be too weak and the phone automatically resets the connection to 3G or E to maintain the stability of voice communication. In such cases, enabling 4G Only (via the engineering menu) will lead to loss of communication ("No network").
- 📱 Make sure that the plan includes traffic 4G/LTE.
- 📱 Check if the limit of high-speed traffic is exhausted (the operator can reduce the speed to 64 Kbps, which visually feels like a high-speed traffic limit). EDGE).
- 📱 Try to move the SIM card to another slot if there are two, as on some models the first slot supports the SIM card. 4G, And the second one is just 2G/3G.
Resetting network settings as a radical method
If software failures in Android have caused the communication module to malfunction, a complete reset of network settings can help. Importantly, this step will not delete your personal files, contacts or applications, but reset all Wi-Fi passwords, Bluetooth settings and mobile network settings to factory values.
Resets can be done via Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth (the path may vary depending on the version of MIUI). Once confirmed, the phone will restart.
This action often solves problems when the phone "does not see" the tower of a certain frequency range after updating the firmware. After restarting, the system will re-scan the airwaves and register on the network with the optimal parameters available for your region.
