How to turn off the phone, but leave the Internet on Android

Sometimes a situation arises when a person needs to temporarily drop out of voice communication, but at the same time maintain access to the network for messengers, navigation or downloading content. The standard flight mode on Android blocks all radio modules, which automatically breaks the Internet connection. However, the operating system provides flexible tools for fine-tuning radio modules.

In this article we will look in detail at how to isolate the voice communication channel, leaving active mobile data or Wi-Fi. You'll learn about the hidden features of Airplane Mode, Do Not Disturb settings, and call forwarding methods. This will help you maintain productivity without unnecessary noise.

The solution to the problem depends on the specific device model and firmware version, since manufacturers, such as Samsung, Xiaomi or Pixel, may interpret the standards differently Android. We will look at universal methods and specific settings for different shells.

Modifying airplane mode to save the Internet

The easiest way to turn off calls is to activate airplane mode, and then manually turn on the wireless module. By default, this mode “silences” all transmitters, but the system allows you to selectively return them to the active state. This is a standard feature that does not require root access.

After turning on airplane mode, the network icon in the status bar will disappear, and the airplane icon will become active. At this moment, voice communication and SMS messages are no longer available. Now you need to go to the notification shade and click on the Wi-Fi or Mobile dataicon. The system will restore the Internet connection, ignoring the ban on voice calls.

It is worth noting that when using mobile data after turning on airplane mode, some operators may not provide data services if the underlying network is not registered. In this case, using Wi-Fi is a more reliable option. This method is suitable for quickly isolating calls on any device.

⚠️ Attention: When airplane mode is active, incoming calls will be immediately dropped or sent to voicemail. The subscriber will hear a standard unavailable message, rather than short beeps.

If your goal is to work in complete silence, but with access to cloud services, this method is ideal. It physically turns off the cellular radio module, preventing any attempts to dial, even emergency ones (depending on the legislation of the region).

Setting the Do Not Disturb (DND) mode

An alternative to completely disabling the radio module is software filtering of incoming events through the function "Do not disturb". Unlike airplane mode, the network remains fully active here, but the system blocks sound and vibration notifications. This allows you to stay in touch visually without being distracted by calls.

To set up, go to Settings → Sound and vibration → Do not disturb. You can create exceptions in this menu. For example, allow repeat calls from one number within 15 minutes or let calls only from selected contacts. This gives you flexibility that airplane mode does not.

It is important to set your blocking settings correctly. You can choose to completely bar all calls or allow them only during certain hours. Modern versions Android also allow you to hide visual notifications on the lock screen, making the phone virtually “invisible” to strangers.

Using automatic rules in this section allows you to set up a schedule. The phone will automatically go into silent mode during business hours or at night, while remaining active Internet for background data downloading. This is a softer method of isolation compared to hardware shutdown of modules.

Using call forwarding

If you need the phone not to ring at all, but the Internet to work at full capacity, you can redirect all incoming calls to another number or to operator's voicemail. This method does not disable the SIM card, but changes the route of the incoming signal.

Setting is carried out through the phone menu or using USSD codes. The universal code for forwarding all voice calls looks like **21*forwarding number#. Instead of a number, you can enter your operator's voicemail code. After activation, all calls will go there without disturbing your device.

Forwarding type	USSD activation code	USSD code cancellation	Description of action
All calls	**21*number#	##21#	Redirects any incoming call
If busy	**67*number#	##67#	Works only when active conversation
If unavailable	**62*number#	##62#	Triggered when the phone is turned off or offline
No answer	**61*number#	##61#	Redirection after a long beep

The advantage of this method is that it works at the operator network level. Even if your smartphone runs out of battery or loses signal, calls will still not disturb you as they will be redirected before reaching the device. At the same time, mobile data the phone itself continues to function normally.

The subtleties of working with voice mail

Many operators provide voice mail service for free or for a nominal fee. Setting up forwarding to a special voicemail number allows callers to leave messages that you can listen to later through the operator’s Internet application or a regular call to your number from another phone.

Disabling only voice communication through the engineering menu

For advanced users, there is a way to disable the voice domain of the network, leaving packet data transmission (GPRS/EDGE/LTE/5G). This is done through the engineering menu, access to which depends on the device processor (MediaTek, Qualcomm).

On devices with processors MediaTek you can enter the code ##3646633## in the phone. In the menu that opens, you need to go to the Network Selecting or BandModetab. Here you can uncheck voice-only modes, although modern LTE standards often combine voice and data (VoLTE), which complicates the task.

A safer option is to use network mode switching applications such as Force LTE Only. These utilities switch the phone to operating mode only with 4G/LTE. In some regions and for some operators, voice calls do not go through in this mode if VoLTE is not configured, and the Internet continues to work at high speed.

⚠️ Attention: Interfering with the radio module settings through the engineering menu may lead to loss of the network. If you do not see the operator icon after the changes, restart the device or reset the network settings.

This method is the most technically complex and is not 100% guaranteed, since network behavior depends on the policy of the telecom operator. However, it allows you to achieve the goal “there is Internet, no calls” without using airplane mode.

Blocking all incoming numbers

Another radical but effective method is using the “Blocking all incoming” function. This option is often hidden deep in the Phone app's settings. It prohibits the passage of any calls to the device, essentially turning it into a device for outgoing communications and the Internet only.

To activate this function, open the application Phone → Settings (three dots) → Number blocking. In the list of options, find the “Block all incoming” item. The system may request a password, which is usually set through the operator menu or is standard (0000, 1234).

• 📵 Full silence: The phone will not ring at all, the screen will not light up.
• 🌐 Internet active: Mobile data and Wi-Fi work without restrictions.
• 📞 Outgoing available: You can call anyone at any time.
• 📩 SMS can be received: Please note that this setting is usually not blocks text messages.

This creates the effect of a switched-off phone for the caller, although your device is fully functioning on the network.

Comparing methods and choosing the optimal solution

Each of the methods discussed has its own advantages and disadvantages depending on your specific situation. Airplane mode with Wi-Fi on is the fastest, but it cuts you off from the mobile network completely. The “Do not disturb” mode leaves the possibility of emergency dialing, which can be both a plus and a minus.

Forwarding and blocking of incoming calls work at the level of call processing logic, without affecting the physical communication layer. These are the most stable methods for maintaining mobile data. The choice depends on whether you need to retain the ability to receive SMS or see missed calls in the log.

If you use a smartphone to work in the field, where only the Internet is important for transmitting telemetry or data, and voice communication only wastes battery life and distracts, a combination of these settings will optimize the operation of the device. Don't forget to periodically check your settings so you don't miss a really important call after the isolation period ends.

⚠️ Attention: Settings interfaces may differ on different versions of Android (10, 11, 12, 13, 14) and shells (One UI, MIUI, ColorOS). If you do not find the described item, use the search in the phone settings.

Frequently asked questions (FAQ)

Will SMS be received if I turn on airplane mode and then Wi-Fi?

No, when airplane mode is turned on, the cellular module is disabled, so regular SMS will not be delivered there will be. they will come only after turning off airplane mode. However, messages in Internet instant messengers (Telegram, WhatsApp) will arrive normally via Wi-Fi.

Is it possible to receive calls via Wi-Fi by turning off the mobile network?

Yes, if your operator and phone support VoWiFi (Voice over Wi-Fi) technology. In this case, you can turn off mobile data and even the SIM card for voice, but calls will go through the Wi-Fi Internet channel. The setting must be found in the SIM card menu.

Will the alarm work if the phone is in Do Not Disturb mode?

Yes, the system alarm on Android works even in Do Not Disturb mode and airplane mode. The alarm sound takes precedence over the silence settings so that you don't oversleep an important event.

Will the caller see that I have turned off the phone, or will he hear a beep?

When using incoming forwarding or blocking, the caller usually hears a long beep, and then a reset or voice message. In airplane mode, he most often immediately hears a message that the subscriber is unavailable.

Does the battery drain faster if you leave the Internet on when the phone is turned off?

Technically, you cannot leave the Internet on when the phone is completely turned off. If you mean airplane mode with Wi-Fi turned on, then battery consumption will be minimal, since the most energy-intensive module (cellular communication) is disabled.
