In the modern world, high-speed mobile data has become the standard, but there are situations when technology LTE becomes more of a hindrance than a helper. Users of smartphones based Android often face the need to forcefully switch the network mode to an older standard 3G or even 2G. This may be caused by a desire to save battery power, an unstable signal in remote areas, or the need to hide the 4G/LTE icon in the status bar.
The process of deactivating the fourth generation of communications is not complicated, but the path to the necessary settings may vary significantly depending on the device manufacturer and operating system version. In this article, we will analyze in detail the standard methods of disabling, using the engineering menu and third-party applications, so that you can choose the best option for your gadget.
Before you start changing the parameters, it is important to understand that refusing to 4G automatically limit the maximum data transfer speed. If your goal is simply to reduce traffic consumption or improve the stability of voice calls in an area of poor coverage, then switching to WCDMA or GSM will be an effective solution.
Why turn off high-speed Internet at all
Many users wonder why it is worth limiting the capabilities of their modern smartphone. The main reason lies in the physics of the radio module. When the phone is at the edge of the coverage area LTE, it constantly tries to maintain a connection with the tower, constantly switching between standards. This process causes increased power consumption and heating of the case.
In addition, in some regions, third generation network infrastructure 3G operates more stable than overloaded fourth generation towers. Voice calls through technology VoLTE are not supported by all operators and not on all tariffs, therefore, when making a call, the phone often resets the connection to 3Gwhich leads to a break in the Internet session. Fixing to one standard eliminates these jumps.
⚠️ Warning: Disabling 4G will significantly reduce web page loading speeds and prevent you from viewing high-definition videos. Make sure that the current tasks do not require high bandwidth.
It is also worth mentioning situations when the icon 4G is visually annoying or the user wants to prevent background updates of applications via the mobile network. In such cases, switching to the mode 3G only acts as an effective software traffic limiter without having to completely turn off mobile data.
Standard method through phone settings
The safest and most accessible method of changing the network type is in the standard settings menu Android. The interface may differ slightly on devices of different brands, such as Samsung, Xiaomi or Pixel, but the search logic remains the same. You will need to find the section responsible for connections and SIM cards.
Usually the path looks like this: you need to go to Settings, then select item Connections or Network and Internet. Next, go to the menu Mobile network and find the item Mode network or Network type. Here the system will offer a list of available options, among which you need to select a combination without mentioning LTE or 4G.
- 📱 Select an option
3G/2G (auto)to automatically switch between standards. - 📶 Option
Only 3Gwill forcibly fix the connection on third generation networks. - 📞 Mode
Only 2Gwill provide maximum energy savings, but will leave only voice communication and SMS.
If there is no explicit indication of disabling in the list 4G, look for an item with the name Preferred network type. In some firmware, for example based MIUI or OneUI, this parameter may be hidden in the specific settings submenu SIM cards, especially if the device uses two active slots.
☑️ Check before changing mode
Using the engineering menu for advanced users
For those cases when the standard menu does not provide the necessary options or does not work correctly, you can use the engineering menu. This is a hidden section of the system intended for testing equipment and fine-tuning the radio module. It is accessed through a special code entered in the application Phone.
The most universal code for devices on processors MediaTek is ##3646633##. For smartphones based on Qualcomm the combination ##4636##often works. After entering the code, the service menu will open, where you need to go to the Phone Information or Phone informationtab. There you will see a drop-down list Set Preferred Network Type.
##4636##
##3646633##In this list you need to find a value that does not contain an abbreviation LTE. The optimal choice would be WCDMA Only (3G only) or GSM Only (2G only). Be extremely careful: changing other parameters in the engineering menu may lead to signal loss or incorrect operation of the device.
⚠️ Attention: The engineering menu interface depends on the chipset manufacturer. Incorrectly changing the radio module settings may require resetting the network settings or reflashing the device to restore functionality.
What to do if the code does not work?
If standard codes do not open the menu, the manufacturer could block access to them in its shell. In this case, try installing the Engineering Mode Shortcut application from the Play Market store, which creates a shortcut to hidden system settings.
Third-party applications for network management
If manual configuration seems too complicated or the buttons in the engineering menu are inactive, specialized utilities from the store will come to the rescue. Google Play. Applications like Force LTE Only (4G/5G) or NetMonster allow you to control your preferred network type through a software interface, bypassing standard shell restrictions.
Such apps often use the same system calls as the engineering menu, but provide a more user-friendly interface. After installing the application, you will need to give it the necessary permissions, after which you can select the desired operating mode of the modem in one click. This is especially convenient for frequently switching between modes.
- 🚀 The application Force LTE Only allows you to quickly activate the "4G Only" mode or return to standard settings.
- 📡 The utility Network Cell Info gives detailed information about towers and allows you to change standards communication.
- 🛠 The tool Mobile Network Type offers a simple switch without unnecessary technical details.
It is worth considering that the operation of such applications may be limited to versions Android above 10 or 11 due to stricter Google security policies. In new versions of the OS, access to changing the radio module is strictly regulated, so some functions may not be available without root access.
Before installing third-party network management applications, check reviews and the date of the last update by the developer. Outdated utilities may not work correctly on new versions of Android.
Features of disabling 4G on different brands
Smartphone manufacturers often modify the standard one Androidby adding their own shells, such as One UI, MIUI, ColorOS or EMUI. This affects the layout of menu items and available settings. Below is a table with approximate paths for popular brands.
| Brand | Path to settings | Features |
|---|---|---|
| Samsung | Connections → Mobile networks → Network mode | Often hidden with two SIM cards |
| Xiaomi / Redmi | Settings → SIM cards and mobile networks → Network type | May require entering a code in the call menu |
| Huawei / Honor | Mobile network → Preferred network type | In new versions of EMUI, the item may be missing |
| Pixel / Motorola | Network and Internet → Mobile network → Preferred type | Pure Android, standard settings |
On devices Samsung with two With active SIM cards, the network mode selection item often disappears from the menu. In this case, you need to temporarily disable the second SIM card in the settings in order to gain access to selecting the standard for the main one. After changing the settings, the second card can be activated back, but the mode may be reset.
Smartphone owners Xiaomi may encounter the fact that there is no “3G Only” option in the network type selection menu. In this case, it helps to activate the hidden menu through the code ##4636##, which works on most devices of this brand regardless of the version MIUI.
⚠️ Attention: Settings interfaces may change with firmware updates. If you do not find the specified item, use the search in the phone settings by entering the request “Network mode” or “Network type”.
The location of the network settings directly depends on the manufacturer’s shell. If the standard path is not suitable, use a search in the settings menu or engineering code.
The impact of disabling LTE on autonomy and communication
The transition to third or second generation networks has a direct impact on the operating time of the device on a single charge. The module 4G consumes significantly more energy when searching for a signal and transmitting data, especially in unstable coverage conditions. Disabling this technology can extend the life of the smartphone by 15-20% in standby mode.
However, there is another side to the coin. If the towers in your area are 3G located far away, the phone will operate at maximum transmitter power to maintain the connection. In such a scenario, battery savings may be offset by constant network searching. It is recommended to test the operation of the device in different locations before the final transition.
It is also worth remembering the quality of voice communication. Modern operators are increasingly using technology VoLTE for voice transmission over fourth generation networks. If you force a switch to 3G you will lose the ability to make calls via LTE, which in some cases can lead to deterioration of voice intelligibility or increased call time.
Is it possible to disable 4G for only one SIM card?
Yes, in dual-SIM smartphones, network type settings are usually applied individually for each slot. Go to the settings of a specific SIM card and change the preferred network type only for it, leaving the second one in 4G/3G/2G mode.
Frequently asked questions
Why did the phone turn on 4G again after rebooting?
Some telecom operators and smartphone firmware are set to automatically return to the fastest available network standard when the device reboots. To avoid this, try using third-party applications that can capture the setting, or check to see if your operator activates the settings profile automatically when you insert a SIM card.
Will you receive SMS and calls in 2G mode?
Yes, technologies GSM (2G) fully support voice calls and text transfers messages SMS. However, the transmission of multimedia messages MMS may be unstable or require manual configuration of the access point APN for second generation networks.
How to get 4G back if the Internet is lost?
To return, you need to go to the mobile network settings and select the mode LTE/3G/2G (auto) or a similar item with a mention 4G. If the settings do not apply, try turning Airplane Mode on and off or restarting the device to re-register on the network.
Does turning off 4G affect the speed of the navigator?
The loading speed of maps and traffic jams in navigation applications directly depends on Internet speed. In mode 3G Data loading will be slower, which may lead to delays in updating traffic conditions. It is recommended to download offline maps in advance when using networks.
Is it possible to disable 4G without root access on Android 13?
Yes, in most cases this is possible through the standard settings menu or engineering code ##4636##. However, on some new models with pure Android 13, access to changing the preferred network type through the engineering menu may be closed by the manufacturer for security reasons.
