In some situations, you need to temporarily block incoming calls on your smartphone Android, but at the same time maintain access to mobile data. For example, during an important online conference, exam, sleep or work in do not disturb mode. The standard disabling of the mobile network through the notification panel (Airplane mode) also breaks the Internet connection, which is not always convenient.
In this article we will look 5 proven methodshow to disable only voice calls, leaving 4G/5G active for instant messengers, mail and other online services. The methods work on most devices - from Samsung Galaxy to Google Pixel i Xiaomi Redmi, including smartphones with clean Android and proprietary shells (One UI, MIUI, ColorOS). You will also learn how to avoid accidentally blocking important calls and what to do if the Internet is lost after the changes.
Why you canโt just turn on โAirplane Modeโ
Many users try to solve the problem by activating Airplane mode (or "Airplane Mode") in the notification shade. However, this method has critical drawbacks:
- ๐ต Complete network shutdown: along with calls, the mobile data also disappears, and Wi-Fi must be turned on manually.
- โก Increased battery consumption: when the mode is frequently switched, the smartphone spends additional energy searching for a network.
- ๐ Inconvenience: you have to constantly turn the mode on/off if you need to temporarily receive a call.
Moreover, on some devices (for example, Huawei s EMUI) After exiting airplane mode, mobile data is restored with a delay of up to 30 seconds. And if you use VoLTE (voice communication over 4G), then you risk missing an important call due to a failure in switching between networks.
Method 1: Using the Do Not Disturb (DND) mode
The most universal method is to activate the mode Do not disturb (Do Not Disturb, DND) with setting exceptions. This method works on all versions Android from 6.0 and higher, including the latest updates Android 14.

- ๐ Allow repeated calls from one number within 15 minutes (useful for emergencies).
- ๐ฑ Leave sound alerts for alarms and media.
โ๏ธ Checking DND settings
โ ๏ธ Attention: On Xiaomi s MIUI 14 i Samsung One UI 5.1 in mode DND is blocked by default all notifications, including messages in WhatsApp and Telegram. To avoid this, in the rule settings, selectSound notifications onlyโAllow silent notifications.

If the Internet is not restored, restart your smartphone or manually switch the network type from 4G on 3G and back.
Method 3: Forwarding calls to a non-existent number
If the previous methods did not work (for example, on old versions Android or custom firmware), you can use forwarding service from the operator. All incoming calls will be redirected to an invalid number, and the Internet will remain active.
How to set up:
- Open the application
Phoneand dial the combination:*#21#This is a command to check the current forwarding settings.
- If forwarding is disabled, enter:
