The problem is relevant for owners of devices of all brands - from Samsung Galaxy to Xiaomi Redmi, from Google Pixel to HonorThe methods work on Android 10–14, but may differ slightly depending on the manufacturer's shell (MIUI, One UI, EMUI, etc.). We will also consider Hidden settings for advanced users, which allow flexible control of the smartphone's radio modules without loss of functionality.

Why turn off cellular service while leaving Wi-Fi?

At first glance, this seemingly simple task has several practical applications:

• 🔋 Battery saving4G/5G radio modules consume up to 30% of the battery, even in standby mode. Disabling cellular data extends the smartphone's battery life by 10–15%.
• 📵 Privacy: Without a SIM card or an active cellular network, it is more difficult to track your location through carrier towers.
• 🎮 Gaming and Streaming: many online games (for example, Genshin Impact or Call of Duty Mobile) require stable Wi-Fi, but calls or SMS may interrupt gameplay.
• 👶 Child control: Limit calls and mobile data while maintaining access to educational materials via home Wi-Fi.

Moreover, in some countries, roaming is extremely expensive, and turning off your cellular service helps avoid unexpected bills from your carrier. And if you use your smartphone as a media player or e-reader, you simply don't need a data connection.

Method 1: Use Wi-Fi Only mode in Quick Settings

The most obvious and quickest method is to use the notification panel. However, there's a catch: the default Airplane mode disables all wireless modules, including Wi-Fi and Bluetooth. To bypass this limitation:

1. Pull down the notification panel twice to reveal quick settings.
2. Find the icon Airplane mode (airplane) and activate it.
3. Without closing the panel, immediately turn on Wi-Fi (wave icon).
4. Connect to the desired network - cellular communication will remain disabled, but Wi-Fi will work.

This method works on most devices, but on some firmware (for example, ColorOS from Oppo/RealmeWi-Fi may automatically turn off after 5-10 minutes. In this case, proceed to the next method.

Method 2: Disable mobile data and calls in Settings

If you need to keep Wi-Fi but completely disable cellular service (including calls and SMS), follow these steps:

1. Open Settings → Connections (or Network and Internet on stock Android).
2. Go to the section Mobile network (may be called SIM cards and mobile networks).
3. Turn off the switches:
   • 📶 Mobile data (or Data transfer)
   • 📞 Mobile network calls (if there is such a clause)
   • 💬 SMS (on some devices)

Return to the main settings menu and make sure Wi-Fi is turned on.

On Samsung with shell One UI the path will be like this: Settings → Connections → Mobile networks → Network mode → select Wi-Fi only (if available). On Xiaomi (MIUI) search Settings → SIM cards and mobile networks → Data transfer.

What if there is no "Wi-Fi Only" option?

On some devices (eg. Google Pixel) this item is missing. In this case, use Method 3 or 4 from this article.

Method 3: Using Do Not Disturb mode with exceptions

If your goal is to block calls and notifications from the operator, but maintain access to instant messengers (WhatsApp, Telegram) via Wi-Fi, set up the "Do Not Disturb" mode (DND):

1. Open Settings → Sound & Vibration → Do Not Disturb (or Settings → Notifications → Do Not Disturb).
2. Activate the mode and select No sound or Alarm clocks only.
3. Click Exceptions and allow:
   • 🔔 Notifications from messengers (select apps manually).
   • 🔔 Alarms and reminders.

Turn off mobile data in settings (Method 2).

This method doesn't completely disable cellular communications (your phone will still be available for emergency calls), but it does block all notifications from your carrier and third-party apps, except for those you've added as exceptions.

Method 4: Disabling the radio module through the engineering menu (for advanced users)

If standard methods don't work (for example, on custom firmware), you can manually deactivate the radio module through the engineering menu. Attention: Incorrect actions here may result in loss of network or device failure.

Instructions for devices based on Qualcomm Snapdragon (majority Samsung, Xiaomi, OnePlus):

1. Open the app Telephone and enter the combination:

   ##4636##

2. Select Phone information (or Phone Information).
3. Scroll down to the block Set preferred network type.
4. Select Disable radio (or Turn off radio).
5. Confirm the action - the cellular connection will be disabled, Wi-Fi will remain active.

For devices on Mediatek (many models Realme, Oppo, Tecno) the combination is different:

##36446337##

After entering the engineering menu, find the item Connectivity → Radio Control and deactivate the radio module.

⚠️ Note: After disabling the radio module through the engineering menu, a device reboot may be required to restore communication. Some operators (e.g. MTS or Beeline) may temporarily block the SIM card if frequently reconnected.

Manufacturer	Combination for the engineering menu	How to disable the radio module
Samsung	##4636##	Phone Information → Turn off radio
Xiaomi/Redmi	##4636## or ##6484##	Phone Info → Disable DSDS
Google Pixel	##4636##	Phone Information → Disable radio
Huawei/Honor	##2846579##	Project Menu → Background Settings → Radio Control

Method 5: Communication Management Apps

If manual settings seem complicated, use specialized utilities. They allow you to create connection profiles and quickly switch between them.

• 📱 Network Signal Guru (For Qualcomm): gives access to hidden settings of the radio module, including forced disabling of 2G/3G/4G.
• 🔄 Tasker: allows you to automatically turn off mobile communications when connected to a specific Wi-Fi network (for example, at home or at work).
• 🛡️ Airplane Mode Toggle: Adds a widget to quickly switch to Airplane mode while maintaining Wi-Fi.

Example of setting in Tasker:

1. Create a new task (Task).
2. Add an action Net → Mobile Data and install Off.
3. Add a condition (Context): State → Net → Wi-Fi Connected (Please enter your network SSID).
4. Save your profile - now mobile data will be turned off automatically when you connect to your home Wi-Fi.

⚠️ Warning: Apps like Network Signal Guru demand rights root on some devices. Without them, functionality may be limited. Before using, check reviews in Google Play - Some utilities contain aggressive advertising.

Common problems and their solutions

Even after disabling cellular service, users still encounter unexpected issues. Let's look at common scenarios and how to resolve them:
