How to disable the second line on an Android smartphone

Using two numbers on one device has become the norm for a modern Android user, but not everyone needs this mode all the time. Often a situation arises when you need to temporarily or permanently remove a second line, be it a physical SIM card, a virtual number or a forwarding service. In this article we will analyze in detail all the possible ways to deactivate an additional communication channel.

The deactivation procedure can differ radically depending on what exactly is hidden under the term “second line”. This could be a checkbox in the phone settings, a service from a mobile operator, or a third-party application. A lack of understanding of the source of the problem often leads to users wasting time on the wrong settings menus.

We will look at all the technical nuances, from simple switches in the interface to complex USSD requests. You will learn how to properly manage your communication lines so as not to miss an important call, but at the same time avoid paying for unnecessary services. It is important to approach the issue systematically, checking each level of configuration of your device.

Built-in settings for SIM cards in the Android system

The most common scenario is that the phone has two physical or one physical and one eSIM cards. The Android operating system provides a native tool for managing them. To disable the second line in this case, just go to the settings of your mobile device. The path to the desired menu may vary slightly depending on the firmware version and the manufacturer's shell.

Usually you need to open the section Settings, then go to the item Connections or Network and Internet. Here you will find subsection SIM card manager or SIM card management. It is in this menu that all active communication lines are displayed. Disabling is done by simply pressing the switch opposite the desired slot or number.

• 📱 Go to settings and find the SIM card management section.
• 🔘 Find the switch opposite the second SIM card (SIM 2).
• ⏹ Click on it to change the status to the "Off" position.
• 📡 Make sure the network icon disappears from the line state.

After turning off the second SIM card, the system will stop receiving calls and SMS to this number, but the card itself will remain in the phone. This is convenient if you want to save your number but don't want to be disturbed temporarily. In some models, for example Samsung Galaxy or Xiaomi Redmi, the interface may have additional options, such as selecting a card for the mobile data by default.

⚠️ Attention: If you disable the second SIM card through the Android settings, you will not be able to receive calls to this number, even if it is active with the operator. The caller will hear a “subscriber unavailable” signal.

If you use the function Dual SIM Dual Standby, disconnecting one line frees up the radio module for more stable operation of the remaining network. This can be useful in areas of poor reception where the phone is constantly switching between towers of different operators, trying to maintain two active lines.

Disconnecting the "Second Number" service from the operator

Often, the second line does not mean a separate physical card, but a virtual number provided by your mobile operator. Services such as “Second Number” from MTS, “Additional Number” from Beeline or similar offers from MegaFon and Tele2 allow you to have two numbers on one SIM card. Such lines are managed differently than regular SIMs.

To disable such a service, the settings of the phone itself will not help, since the virtual number is emulated on the network side. You will need to use a USSD request, operator’s personal account or contact with technical support. Each operator sets its own unique codes for activating and deactivating the service.

Operator	Service name	Disconnection code	Method
MTS	Second number	*111*222#	USSD request
Beeline	Additional number	*110*1051#	Services menu
MegaFon	Additional number	Personal account	Application
Tele2	Second number	*155*611#	USSD request

In addition to USSD codes, many users prefer to use official operator applications. In the application interface My MTS, My Beeline or MegaFon you can find a section with connected services. There, the disabling process looks as clear as possible: you simply find the service in the list of active ones and click the “Disable” button.

It is worth considering that some tariff plans include a second line as mandatory option. In such cases, complete shutdown may not be possible without changing the tariff. If you cannot disable the service using standard methods, it may be part of a package Family or corporate tariff.

Managing applications for virtual numbers

The third popular option is to use third-party applications that provide virtual numbers. Services like Zadarma, TextNow or Google Voice work over the Internet (VoIP) and do not require a physical SIM card. Disabling the second line here means logging out of your account or deleting the application.

If you see a second phone icon in the notification line, most likely such an application is running. To stop it from working, you need to go to the Android settings, select the section Applications and find the appropriate app. In the application menu, you can select the option Stop or Disable, which will prevent it from running in the background.

To completely remove the second line created through the app, you must perform the following steps:

• 🗑 Remove the application itself from the desktop or through the settings.
• 🚫 In the application settings, find the "Numbers" section and delete the virtual number.
• 📧 Cancel your subscription in Google Play or the App Store if the service was paid.

It is important to understand the difference between simply closing the application and refusing the number. If you simply close the app, the number may remain with you, and the subscription fee will continue to be charged for it. Complete release of the line requires an explicit refusal of the number in the service interface.

⚠️ Attention: When deleting the application without first abandoning the number in the personal account of the service, the virtual number may be blocked for non-payment, but the debt will continue to accumulate.

Some users use shell applications that combine several instant messengers and phone books. Check to see if the “second line” is simply a shortcut to a second WhatsApp or Telegram account created through the app cloning feature.

Disabling call forwarding and parallel calling

Sometimes users perceive call forwarding as a second line. If calls from the main number come to another phone, the illusion of two lines is created. This is actually a traffic redirection setting. You can check and disable these settings directly in the Phone application.

Open the standard dialer, click on the three dots in the corner of the screen and select Settings. Find the section Calls or Advanced settings. There will be an item here Call forwarding. The system may request an operator code to obtain the current status of network settings.

##002#

Entering this universal code in dialing allows you to disable all types of forwarding (when the subscriber is busy, does not answer or is unavailable) instantly. This action resets all previously configured rules for forwarding calls to other numbers, returning call control exclusively to your device.

It is also worth checking the “Parallel Call” or “Simultaneous Call” function, which allows you to call several numbers at once when there is an incoming call. This feature is often activated accidentally or suggested by the operator when connecting. It can also be disabled through the call settings menu or the operator's USSD commands.

What to do if the code does not work?

If the universal code ##002# does not work, it means that the forwarding service is blocked by the operator at the tariff level or requires entering a PIN code. In this case, contact your operator's support service.

Specifics of working with eSIM on Android

ESIM technology - a built-in digital SIM card - is increasingly found in modern flagship smartphones. Managing it has its own characteristics. Unlike a physical card, the eSIM cannot be removed from the slot, but it can be disabled programmatically or the profile can be completely deleted from the device memory.

To temporarily disable the second line on the eSIM, simply turn the switch to the "Off" position in the SIM card management menu, as described in the first section. However, if you want to get rid of this line completely, you need to remove the profile. This action is irreversible without re-downloading the QR code from the operator.

The process of deleting a profile is as follows:

1. Go to Settings → Connections → Manager SIM cards.
2. Select the eSIM profile you want to delete.
3. Press the button Delete profile or Erase eSIM.
4. Confirm the action by entering the screen unlock PIN.

After deleting, the profile disappears from the list of available networks. If you plan to use this number again on this device in the future, you will have to request a new QR code from your operator for activation, as the old profile will be lost. This is an important point for those who often change devices or tariffs.

⚠️ Attention: Deleting an eSIM profile cannot be undone. Make sure you have a backup communication method or a new QR code from your operator before performing this operation.

Some operators allow you to manage eSIM profiles remotely through their apps. In such cases, deleting a profile from the phone settings can automatically synchronize with the operator's base, completely deactivating the line on their side.

Solving problems if the line does not disconnect

There are situations when the user follows all the instructions, but the second line continues to be displayed in the system or receive calls. This could be caused by a software glitch, a stuck radio service, or a configuration conflict. In such cases, more in-depth diagnostics are required.

First, try rebooting the device. This is a simple but often effective way to reset temporary network errors. If rebooting doesn't help, check to see if Airplane mode is activated. Sometimes turning this mode on and off helps to re-register the phone on the network and update the status of the SIM cards.

If the problem persists, it may be a cache issue in the Phone application or system services. Clearing the cache can solve the problem of incorrect display of line status:

• 🛠 Go to Settings → Applications.
• 📞 Find the application Phone (or Phone).
• 🧹 Select Storage and click Clear cache.

In rare cases, you may need to reset your network settings. This action will return all settings. Wi-Fi, Bluetooth and mobile networks to factory settings. Your personal data (photos, contacts) will not be affected, but the saved Wi-Fi passwords will have to be entered again.

⚠️ Attention: Resetting the network settings will delete all saved Wi-Fi passwords and paired Bluetooth devices. Use this method only if other methods did not help.

If none of the above worked, the problem may be on the operator's side. The service may not have been disabled correctly in their database, or a synchronization failure may have occurred. In this case, the only correct way is to call technical support with a request to check the status of services on your number.

Frequently asked questions

Is it possible to disable the second line temporarily and then turn it back on?

Yes, this is possible if we are talking about a physical SIM or eSIM, you can simply turn off the switch in the Android settings, and the number will remain active with the operator. You can turn it back on at any time. If you deleted the eSIM profile or disabled the service via USSD code, reactivation will require a new setting or a request from the operator.

Will SMS be sent to a disabled second line?

No. If you have disabled the SIM card in the phone settings or deleted the virtual number, SMS will not be received. If you have disabled only voice calls through forwarding, SMS may continue to be sent to the main number or to the number where forwarding is configured, depending on the operator’s settings.

Does disabling the second line affect Internet speed?

In some cases, this can improve the stability of the connection. When the phone operates in dual active SIM (DSDS) mode, it is forced to constantly switch between networks to maintain registration. the second card. Disabling one line allows the radio module to focus on one network, which can have a positive effect on speed and ping.

How to learn how much the “Second Number” service costs?

The cost depends on the tariff of your operator. and services, which is specific to each operator (for example, *100# or *105#).
