How to turn off mobile data but keep Wi-Fi working

Do you want to save battery life, avoid unnecessary calls or simply not waste mobile data, but still stay connected through Wi-FiThis problem arises in a variety of situations: during trips abroad (to avoid roaming charges), at important events (to avoid being distracted by text messages), or when working with devices that only require internet access without voice calls. Fortunately, modern smartphones, tablets, and even laptops offer flexible connection management—the key is knowing where to find the right settings.

In this article we will look at all possible ways Disable your mobile network (2G/3G/4G/5G) while maintaining an active Wi-Fi connection. Instructions are provided for Android (including Samsung, Xiaomi, Huawei etc.), iPhone (iOS), as well as for Windows On laptops with a SIM card. We'll pay special attention to the nuances: for example, why some apps (like banking apps) may stop working after disabling mobile data and how to work around this. If you need to do more than just "cut off the internet," but specifically Maintain Wi-Fi when your cellular connection is completely disconnected, including calls and SMS. - You will find the exact steps here.

Why can't you just turn off your mobile internet?

Many users think that it is enough to disable Mobile data in the settings—and the problem is solved. However, this doesn't always work. Here's what actually happens:

• 📶 Mobile data ≠ cellularDisabling only mobile data doesn't block calls and text messages. The phone will still connect to the carrier's network, but the battery will drain searching for a tower.
• 🔄 Automatic switchingSome devices (especially iPhone) can automatically connect to a mobile network if the Wi-Fi signal is weak - even if you manually turned off data transfer.
• 🔒 Application limitations. Banking apps, messengers with two-factor authentication (like Telegram or WhatsApp) and some services check for the presence of a SIM card. Without an active cellular connection, they can block access.

To completely disconnect from the operatorWhile maintaining Wi-Fi, you need to use other methods—we'll discuss them later. For now, remember: if your goal is battery saving, then simply disabling mobile internet will have minimal effect. You need to disable the internet itself. cellular network.

Method 1: Airplane mode with Wi-Fi enabled (universal)

The most reliable and universal method is to use Airplane mode (or "Airplane Mode"), and then manually turn on Wi-Fi. This method works on all smartphones (Android, iOS), tablets, and even some laptops with a SIM card. Its main advantage: complete disconnection from the cellular network (including calls, SMS and mobile Internet), but maintaining access to Wi-Fi.

How to do it:

1. Open Quick Settings panel (swipe down on Android or up on iPhone).
2. Find the icon Airplane mode (airplane ✈️) and tap on it.
3. Wait 5-10 seconds - the device will disconnect from the operator's network.
4. Now open the quick settings panel again and turn on Wi-Fi (wave icon 📶).

On some devices (eg. Xiaomi or Huawei) After turning on airplane mode, Wi-Fi is automatically disabled. In this case:

5. Go to Settings → Wi-Fi and turn it on manually.
6. Connect to the desired network.

Airplane mode is on (the ✈️ icon is highlighted)

Mobile network is disabled (no antenna icon 📡)

Wi-Fi is turned on and connected to the network (there is a 📶 icon)

Calls and SMS are unavailable (check if the operator icon has disappeared) -->

⚠️ Attention: On iPhone With iOS 16 and later, after enabling Airplane Mode, Wi-Fi and Bluetooth may turn off automatically after 24 hours (if the device is not connected to a charger). To avoid this, immediately turn on Wi-Fi manually after activating Airplane Mode. Settings, and not through the control panel.

Method 2: Disable cellular network in Settings (Android)

If you need selectively disable only cellular communicationsWithout resorting to airplane mode, you can do this on Android through the settings menu. This method is useful when you want to retain the ability to quickly return to a mobile network (for example, for calls) without completely restarting your connections.

Instructions for most devices running Android 10–14:

1. Open Settings → Connections → Mobile network (on some devices the path may differ, for example, Settings → SIM cards and mobile networks).
2. Find the option Mobile network or Cellular communications And turn it off (the switch should turn grey).
3. Go back to the main settings menu and make sure Wi-Fi is turned on (Settings → Wi-Fi).

On smartphones Samsung (One UI) the path might look like this:

Settings → Connections → Mobile networks → Your SIM card name → On/Off switch

On Xiaomi (MIUI):

Settings → SIM cards and mobile networks → Select SIM → Disable mobile network

What should I do if the "Mobile Network" option is missing?

On some devices (especially those with two SIM cards), instead of a separate switch, there may be an option Network selectionIn this case:

1. Go to Settings → Mobile network → Network selection.

2. Select Manually instead of Automatically.

3. Wait for the device to find available networks, but do not connect to any.

This will prevent the phone from registering with the operator's network, but will keep Wi-Fi active.

⚠️ Attention: On some firmware (for example, on ColorOS from Oppo/Realme) Disabling mobile network may also block outgoing calls over Wi-Fi (VoWiFi). If you need Wi-Fi calling, use this instead. airplane mode.

Method 3: Setting up iPhone (iOS) without Airplane Mode

On iPhone Disabling cellular data while keeping Wi-Fi is a bit more complicated than on Android. Apple doesn't provide a direct "disable carrier network" option, but there are workarounds. Let's look at two working methods.

Method 1: Disabling data transfer + blocking calls

This method does not completely disconnect from the operator, but it blocks mobile Internet and calls, leaving Wi-Fi:

1. Open Settings → Cellular.
2. Turn it off Cellular data (top switch).
3. Scroll down and in the section Options turn it off Voice and data (or 4G/5G, depending on the model).
4. Return to Settings → Wi-Fi and make sure the connection is active.

After this, the phone will remain registered to the operator's network (the network name will be displayed), but calls and mobile data will not work. Wi-Fi will remain fully functional.

Method 2: Using SIM Manager (for dual SIM)

If your iPhone supports two SIM cards (eg. iPhone 12/13/14/15), you can turn off cellular communication for one of them:

1. Go to Settings → Cellular.
2. Tap the number of the SIM card you want to disable.
3. Turn it off Cellular network for this SIM.
4. Make sure the second SIM remains active (if you need to make calls) or disable it as well.

⚠️ Attention: This method won't work on a single-SIM iPhone. In that case, the only option left is airplane mode with manual Wi-Fi activation (see Method 1).

Method 4: Disabling the SIM card connection on a laptop (Windows)

If you have a laptop with support LTE/5G (For example, Lenovo Yoga, HP EliteBook, Dell Latitude or Microsoft Surface (With a SIM slot), you can disable mobile data while Wi-Fi is active through Device Manager or Network Settings. Here are step-by-step instructions for Windows 10/11:

Step 1: Disable the mobile adapter

The fastest way is to disable the network adapter responsible for cellular communications:

1. Click Win + X and select device Manager.
2. Expand the section Network adapters.
3. Find a device with a name like Qualcomm Snapdragon X5/X24, Intel XMM or Sierra Wireless (this is a mobile modem).
4. Right click on it and select Disconnect the device.

After this, the mobile connection will be completely disabled, but Wi-Fi will continue to work through a separate adapter.

Step 2: Configure network settings

If you want more flexible control (for example, to disable only data transfer, while leaving the ability to make calls via VoLTE), do the following:

1. Open Settings → Network & Internet → Cellular.
2. In the section Use of data turn it off Allow cellular data usage.
3. If you want to completely turn off the connection, click Additional options and select Turn off cellular communication.

⚠️ Attention: On some laptops (eg. Surface Pro XDisabling cellular data in Settings may cause the Wi-Fi module to malfunction. If Wi-Fi stops working after doing this, restart your device or turn cellular data back on.

Problems and Solutions: What to Do if Wi-Fi Isn't Working

Sometimes, after disconnecting your mobile data, Wi-Fi may become unstable or even disconnect completely. Here are some common issues and solutions:
