Modern wearable gadgets have ceased to be just pedometers or notifications, but have turned into full-fledged communication devices. The function Watch Call allows you to make and receive calls directly from your wrist using the microphone and speaker of the watch, even if the smartphone is in your bag or in another room. For owners of Android devices, this option opens up new possibilities for freedom of movement, but the process of activating it often raises questions among beginners.
Connecting this function is based on a stable connection via the protocol Bluetooth, however, simply pairing devices is sometimes not enough. Many users are faced with the fact that the watch displays contacts, but the sound comes through the phone, or the call button is completely inactive. In this material, we will analyze in detail the algorithm of actions, the necessary permissions and the nuances of the operation of various operating systems so that you can fully use your gadget.
It is worth noting that the implementation of calls may differ depending on the watch manufacturer and the version of Android on your smartphone. Somewhere you need to install third-party software, and somewhere everything is built into a system application Wear OS or a proprietary utility. Let's go through all the setup steps one by one to eliminate possible errors.
Preparing your smartphone and watch for pairing
Before attempting to activate calls, you must make sure that both devices are in good condition and ready to communicate. The basic requirement is to have the wireless module enabled on both gadgets. Go to Settings → Connections → Bluetooth on your phone and make sure the switch is active.
On the watch, the process may look different depending on the shell. Usually it is enough to swipe down the notification shade and click on the Bluetoothicon. If the devices were previously paired, but calls do not work, it is recommended to remove the old pair from the list of devices on your smartphone and connect again. This will clear the connection cache and eliminate possible protocol conflicts.
It is critical to check the operating system version. Outdated software often does not support new voice codecs or phone book synchronization functions. Go to the updates section on both devices and install the latest available packages. Only after this you can proceed to setting up communication profiles.
☑️ Check before connecting
⚠️ Attention: If the watch supports working with two phones at the same time (Dual Phone mode), make sure that in the settings the smartphone with which you plan to communicate is selected as the priority for calls. Otherwise, calls may be routed to another device.
The process of activating a telephony profile in settings
After successful pairing, the Android system automatically requests access to contacts and call history. Often, users click “Decline” out of habit or ignore this window, considering it unimportant. It is this step that blocks the function Watch Call. You need to go to the Bluetooth settings on your phone, find the connected watch in the list and click on the gear icon next to it.
In the menu that opens you will see a list of profiles: “Audio”, “Media”, “Contacts” and others. Make sure that the checkboxes are opposite the items responsible for phone calls and contact synchronization. Without permission to access the phone book, the watch will not be able to display the name of the caller, showing only the number or remaining silent.
Some watch models, especially the budget segment with proprietary OS (not Wear OS), require the installation of a special companion application. This could be Da Fit, VeryFitPro or Zepp Life. Inside such applications there is often a separate switch “Sync contacts” or “Allow calls”, which duplicates the Android system settings.
If, after turning on all the checkboxes, calls still do not go through, try rebooting both devices at the same time. This helps reset frozen telephony services at the system kernel level.
Sometimes it is useful to manually initiate phone book synchronization. In the Bluetooth profile settings of the watch on your smartphone, there may be an “Update contacts” or “Synchronize” button. Press it and wait for the process to complete, which may take from a few seconds to a minute depending on the size of your address book.
Setting up audio routing and speakerphone
The most common problem after connecting is when a call is accepted by pressing the watch, but the conversation is carried out through the phone. This indicates that the profile HFP (Hands-Free Profile) is active, but the audio output has not switched automatically. At the time of an incoming or outgoing call, a button for selecting a sound output device (usually a speaker or Bluetooth icon) appears on the smartphone screen.
Click on this button and select your watch from the list. In most modern smartphones running Android 12 and higher, the system remembers this choice for a specific device. However, if you turn off your watch or move out of Bluetooth range, the setting may be reset. In this case, the procedure will have to be repeated the next time you connect.
It is also worth checking your accessibility settings. In rare cases, enabled mono audio or channel balance features may redirect the audio stream. Go to Settings → Accessibility → Sound enhancement and make sure the balance is set to the center and mono sound is turned off unless you need it for medical reasons.
| Option | Value for calls | Where to check |
|---|---|---|
| HFP profile | Enabled | Bluetooth device settings |
| Access to contacts | Allowed | Menu paired device |
| Media Audio | Optional | Bluetooth settings (for music) |
| Log sync | Enabled | Watch companion application |
Features of working on Wear OS and third-party OS
Ecosystem Wear OS from Google offers the deepest integration with Android smartphones. Here the call function is implemented natively through the Phone application. You don't need third-party utilities, just sign in to the same Google account on your watch and phone. The call interface on such watches practically copies the telephone one, allowing you to dial a number from the keyboard or search for a contact by voice. Owners of watches on other platforms, such as proprietary systems of Huawei and Xiaomi, may encounter restrictions. Often on such devices only answering a call is available, but it is not possible to dial a number from the watch keypad. In this case, the function
Watch owners on other platforms such as RTOS or proprietary systems from Huawei and Xiaomi may face limitations. Often on such devices only answering a call is available, but it is not possible to dial a number from the watch keypad. In this case the function Watch Call works in one-way mode: you see the notification, click “Accept” and speak into the watch, but you can only initiate a call through the phone.
Watches with eSIM support deserve special attention. In this case, Bluetooth is used only for initial setup or contact synchronization. Calls go directly through the cellular network from the watch, bypassing the phone. To activate this feature, you need a separate tariff plan from your carrier and scanning a QR code in the carrier app.
What is the difference between calls via Bluetooth and eSIM?
Calls via Bluetooth only work within a radius of 10-15 meters from the phone, as they use its modem. Calls via eSIM are autonomous - the phone can be turned off or left at home, the watch works as an independent gadget, but requires payment for an additional SIM card.
⚠️ Attention: Settings interfaces may change with firmware updates. If you do not find the described item in the menu, check the official documentation for your specific watch model, as manufacturers often move functions to new sections.
Solving problems with call quality and interruptions
Even with the correct settings, users may complain about a quiet sound, echo, or constant connection interruptions. The main reason lies in radio interference or low battery charge. The Bluetooth protocol is sensitive to metallic obstacles and the operation of other wireless devices, such as Wi-Fi routers or microwave ovens.
If the sound becomes intermittent, try moving away from the sources of interference or switching the Wi-Fi frequency on the router from 2.4 GHz to 5 GHz to free up the airwaves for Bluetooth. It's also worth checking to see if your watch has a power-saving mode enabled, which could limit the transmitter power. Disable it in the quick settings window of your watch.
Another reason for poor communication may be an outdated audio codec. In the developer settings on Android (if you are an advanced user), you can try changing the Bluetooth codec from SBC to AAC or aptX, if your watch supports these formats. This can significantly improve the clarity of voice transmission.
The stability of communication directly depends on the distance and the absence of physical barriers between the human body (which screens the signal) and the devices. Keep your phone in your chest pocket for the best signal.
In cases where the interlocutor complains that he cannot hear you, check the microphone of the watch. Some models have a protective mesh that becomes clogged with dust or clothing lint. Gently clean the microphone opening with a soft brush. Also make sure that during a call you are not covering the microphone with your cuff or hand.
Frequently asked questions about connecting Watch Call
Why does the watch vibrate when calling, but does not show the name?
This means that the “Media” or “Notifications” profile is working, but access to the phone book prohibited. Go to the Bluetooth settings on your phone, select your watch and turn on the “Contacts” or “Phone Book Sync” checkbox.
Can you make calls from your watch if the phone is turned off?
Only if your watch is equipped with its own cellular module (eSIM or Nano-SIM slot). Regular Bluetooth watches are an accessory and require an active connection with a smartphone to make calls.
How can I turn off audio transmission to the watch if I want to talk through the phone?
During a call, tap on the speaker icon on the smartphone screen and select “Phone” or “Speaker”. You can also temporarily disable the “Calls” profile in the Bluetooth device settings without completely breaking the connection.
Why is the connection reset when there is an incoming call?
There is probably a conflict between Bluetooth versions or the low battery of one of the devices. Try “Forgetting” the device in the settings and pairing again. If the problem persists, update the watch firmware.
Does Watch Call work on an iPhone with an Android watch?
The functionality is very limited. Most Android watches only allow you to see the call notification on your iPhone, but do not receive calls through the watch's microphone due to the closed nature of the iOS ecosystem. Full calls are only possible in a pair of Android phone + Android watch.
