Bluetooth calling in smartwatches: How does it work?

Welcome to Blackview (A well-known brand of Android smartwatches and rugged phones) blog. Hope the guide helps.

In short, Smartwatches with Bluetooth calling piggyback on your phone's network. They connect to your phone via Bluetooth, then use your phone's cellular connection to make and receive calls. You initiate calls and chat through your watch's speaker and microphone. It's like having a mini phone on your wrist!

Smartwatches have evolved from simple fitness trackers to miniaturized smartphones on your wrist. One feature that elevates convenience is Bluetooth calling. Let's delve into how this technology works:

The Bluetooth Connection:

• Bluetooth is a short-range wireless technology that allows devices to communicate using radio waves.
• When you enable Bluetooth on your smartwatch and pair it with your smartphone, they establish a connection.
• This connection acts as a bridge, enabling your watch to utilize your phone's cellular network for making and receiving calls.

Making the Call:

1. Initiating the Call: You can initiate a call directly through your smartwatch's interface. This usually involves a phone app on the watch or a dedicated calling function.

2. Leveraging Your Phone's Network: During the call, your smartwatch doesn't use its own cellular connection (unless it has a built-in SIM card). Instead, it transmits call audio and data through the Bluetooth link to your phone, which then utilizes its cellular network to connect with the other phone.

3. Conversation on Your Wrist: Your smartwatch's built-in microphone and speaker become the tools for conversation. You can speak into the watch and hear the caller through the speaker. Here is the detail guide of making phone calls using Bluetooth calling watch.

Receiving Calls:

1. Incoming Call Notification: When a call arrives on your phone, your smartwatch receives a notification mirroring your phone's display.

2. Answering on Your Watch: You can choose to answer the call directly on your smartwatch using the on-screen buttons.

Note

• Not all smartwatches support Bluetooth calling.
• Call quality may vary depending on your smartwatch's speaker and microphone quality, as well as the Bluetooth connection strength (Here is the guide of "How far can Bluetooth reach?").
• Battery life can be impacted by Bluetooth calling, so keep an eye on your watch's charge level during extended calls. Extending reading: Are smart watches safe to wear all the time?

In Conclusion

Bluetooth calling on smartwatches offers convenience, allowing you to make and receive calls without having your phone in your hand. It's a great option for staying connected while on the go or during activities where holding your phone is impractical.
