How to set up and use call hold on Android

Modern smartphones have turned into multifunctional tools that we use not only for personal communication, but also to solve business issues. In the midst of an important conversation, there is often a need to answer a second incoming call so as not to miss critical information from another counterparty. It is in such situations that the function call holdcomes to the rescue, allowing you to pause the current interlocutor without breaking the connection.

Many Android users encounter difficulties activating this option, since the phone book interface may differ depending on the device model and operating system version. Some suggest that this service must be ordered separately from the telecom operator, while on most modern gadgets it is built into the software by default. Understanding the principles of operation of this function significantly increases the efficiency of communication and allows you to professionally manage telephone conversations.

In this article we will look in detail at how to set up and use the hold mode on various devices controlled Android. We will look at standard usage scenarios, possible technical limitations and ways to eliminate common errors that occur when switching between lines.

The principle of operation of call hold technology

The call hold function is based on the capabilities of the cellular network and the software implementation of the telephone module in your smartphone. When you activate hold, the voice flow between you and the other party is temporarily interrupted or redirected to a special operator server where music or waiting tones are played. In this case, the communication channel is not interrupted, which allows you to return to the conversation at any time.

Technical implementation may depend on the type of network you are on. 2G and 3G networks often use call waiting technology, which requires operator support. In more modern 4G (VoLTE) and 5G networks, the switching process occurs almost instantly and with higher quality voice transmission.

It is worth noting that the sound quality of the subscriber on hold depends on the settings of the telecom operator. Some providers offer standard ringtones, others offer silence or advertising messages. It is usually impossible to change this melody on the part of the smartphone user, since this parameter is controlled on the network side.

⚠️ Attention: If you lose the network signal or your battery runs out while a call is on hold, the connection with the person on hold will be disconnected automatically. Make sure the connection is stable before using this function in critical conversations.

Technical nuances of working in roaming

When you are in international roaming, the call hold function may not work correctly or be disabled by default. This is due to the peculiarities of agreements between operators in different countries. It is recommended to check the terms of service with your operator before traveling.

Activating the call waiting service with your operator

Before trying to configure the function in the smartphone menu, you need to make sure that the service itself is activated on your tariff plan. In most cases, mobile operators enable the option "Call waiting" automatically when registering a SIM card, but on some corporate or archive tariffs it may be disabled.

You can check the status of the service and activate it in several ways. The fastest method is to use a USSD request, which works on any phone, even without Internet access. You can also use the operator's personal account or call the support service.

• 📞 Enter the universal code *43# and press the call button to activate the service on most networks.
• 🔍 Use the code #43#to check the current status of the call waiting function.
• 📱 Go to your operator's application and find the "Services" or "Tariff Options" section.

After sending the USSD request, you will receive a confirmation message from the network. If the service has been successfully activated, a corresponding icon may appear in your phone's status bar, although this does not always happen on modern versions of Android. Now your number is ready to receive a second call during a conversation.

Configuring parameters in the Android system menu

After activating the service on the operator's side, you need to check the settings in the phone itself. The interface may differ slightly depending on the manufacturer's shell (for example, One UI from Samsung, MIUI from Xiaomi or pure Android on Pixel), but the logic of actions remains the same.

To access the necessary parameters, open the standard “Phone” application and go to the settings menu. It's usually hidden behind three dots in the corner of the screen or a gear icon. You will need to find the section responsible for additional communication functions.

1. Open the application Phone.
2. Click on the menu button (three dots or profile icon).
3. Select item Settings or Calls.
4. Find section Additional settings or Operator services.
5. Make sure that the switch opposite the item "Waiting" call" is in the active position.

In some cases, the phone may take a few seconds to poll the network and update the switch status. If the menu item is inactive (gray) or gives an error when you try to turn it on, this may indicate problems with network coverage or SIM card settings.

Using the function during a call

When all the settings are completed, the process of using the function becomes intuitive. Imagine the situation: you are talking with the first caller, and suddenly the second incoming call rings. A notification will appear on the screen with the number or name of the new caller and action buttons.

To put the first person on hold and answer the second, you must press the button Answer and hold (sometimes indicated as “Accept and hold”). After this, the first subscriber will hear waiting music, and you will be able to conduct a dialogue with the second.

Lines are controlled through the active call interface. You can switch between interlocutors by pressing the “Switch” or Swapbutton. This allows you to communicate with each of them in turn, without ending any of the conversations.

Action	Button on the screen	Result
Reply to the second call	Answer and hold	The first one is on hold, talking to the second one
Change interlocutors	Switch / Swap	The active interlocutor is put on hold
Merge calls	Merge / Merge	Creating a conference call (three-way conversation)
End current	Hang up	Return to the held subscriber

If you end an active call by pressing the end call button, the system will automatically return you to the first person on hold. This is convenient if the second conversation turned out to be short or erroneous.

Features of working on dual-SIM smartphones

Owners of devices with two active SIM cards (Dual SIM) are faced with additional setup nuances. The call hold logic here depends on which SIM card is being used for the conversation and which one is receiving the second call.

Most modern smartphones implement technology DSDS (Dual SIM Dual Standby), which allows you to keep both cards in standby mode. However, during an active conversation on one line, the second line may temporarily become unavailable for incoming calls, unless the special forwarding function is enabled or if the phone does not support full-fledged DSDA (Dual SIM Dual Active).

If you do not receive notifications about a second call to the second SIM card during a call on the first, check your SIM card management settings. It is possible that the second card is not configured to forward “if busy” to voicemail or to the main card.

⚠️ Attention: On some budget smartphone models with dual SIM cards, the hold function may only work for the main SIM card. The second card in talk mode over the first one can simply drop incoming calls with the message “subscriber is busy.”

For correct operation, it is recommended to go to the SIM card settings and make sure that the call waiting service is activated for both lines through the phone menu or USSD codes indicating a specific SIM card (for example, selecting a card before dialing the code).

Solving problems with holding and switching

Despite Due to the well-functioning technology, users sometimes encounter situations where the function does not work. The second call may not ring, the hold button may be missing, or the connection may drop when you try to switch.

One ​​common cause is outdated Phone app software. Developers regularly release updates that fix communication bugs. Check for updates in the app store Google Play.

• 🔄 Clear the cache of the “Phone” application through the menu Settings → Applications → Phone → Storage → Clear cache.
• 📶 Make sure you have a stable network signal; in areas of poor coverage, the switching functions may not work correctly.
• 📵 Try moving the SIM card to another slot or check its functionality in another device.

If the problem persists after all the manipulations, it may be due to the incompatibility of your tariff plan with the conference call or hold function. Some virtual operators or specific corporate tariffs have restrictions on the number of simultaneous sessions.

⚠️ Attention: The settings menu interface may change after updating the Android operating system. If you do not find the item you need, use the search in your phone settings by entering the query “Call Waiting.”

As a last resort, resetting the network settings can help solve the problem of software conflicts. This action will delete saved APNs and Bluetooth settings, but will return communication settings to factory defaults.

How to reset network settings

Go to Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings. Confirm the action and reboot the device. This often solves problems with incorrect registration of operator services.

Frequently asked questions (FAQ)

Is there an additional charge for using call hold?

The hold function itself is usually free and included in the standard service package. However, the time you spend on the line (even if the other party is on hold) is charged according to your plan as a regular minute of conversation. Check with your operator for conditions.

Is it possible to record a conversation while one of the subscribers is on hold?

With standard Android tools, recording a conversation is often not available due to restrictions in Google's privacy policy. Third-party recording applications may not work correctly in conference or hold mode, recording only one line or silence.

Why can't I hear a dial tone when I put a caller on hold?

It depends on the operator settings. Some providers replace beeps with silence or background music. If you don’t hear anything, this is normal, the main thing is not to end the call with the end call button if you want to return to the conversation.

Does call holding work through instant messengers (WhatsApp, Telegram)?

No, the call holding function described in this article only works for regular cellular communications (GSM/3G/4G). Messengers implement their own logic: when you receive an incoming call via the Internet, you are usually asked to end the current one or answer by interrupting the first one, since VoIP protocols work differently.

How to turn off the waiting music for a subscriber calling me?

The user cannot turn off the waiting music from his phone, since it is generated by the telecom operator's equipment. You can only disable the call waiting service itself, then the second call simply will not go through, and the subscriber will hear a busy signal.
