Imagine effortlessly answering calls while running, shopping, or even during meetings when pulling out your phone would be inconvenient. Modern smartwatches with cellular capabilities make this possible. This guide explores how to maximize your wearable's calling features, covering activation, operation, troubleshooting, and brand-specific setups.

Before using standalone calling features, verify your device's compatibility and complete necessary preparations:

• Check method: Navigate to Settings > System > Date & Time or Settings > Connections > Cellular Network. If no cellular option appears, your watch likely lacks standalone calling capability. Consult your user manual or manufacturer for confirmation.

• Cellular service: Both your phone and watch need active cellular plans. Some carriers offer "number sharing" services allowing both devices to use the same number. Otherwise, your watch requires a separate SIM.
• Carrier compatibility: Verify with your carrier whether they support your watch model and offer appropriate data plans. Some providers have smartwatch-specific packages.

The following steps apply to Wear OS devices. Other platforms may vary slightly.

• Voice commands: Activate Google Assistant (say "Hey Google" or long-press the crown), then say "Call [contact]" or "Dial [number]".
• Contacts/Recents: Open the Phone app, browse contacts or call history, then tap your desired entry.
• Manual dialing: Select the dial pad icon in the Phone app, enter the number, then tap call.

• Answer: Swipe left on the answer icon when receiving a call.
• Decline: Swipe right on the decline icon.
• Quick responses: Some watches allow preset message replies via "More" > "Send message" during incoming calls.

• Options: Swipe up from the bottom mid-call for additional features.
• Dial pad: Access number input for automated systems.
• Hold/Mute: Pause calls or disable your microphone as needed.
• Volume: Adjust call volume via the sound icon.
• Multitasking: Press the side button to return home while maintaining the call.

All cellular watches can dial emergency numbers (e.g., 911, 112) even without active service. Open the Phone app, enter your local emergency number, and dial. Note: While some watches support emergency messages via voice commands, direct calling remains more reliable.

When Bluetooth-connected to your phone, choose whether to use your watch's number or your phone's. Beyond Bluetooth range, watches automatically use their cellular connection.

Enable "Play phone audio" in Bluetooth settings to route your phone's calls through your watch's speaker.

Redirect unanswered phone calls to your watch via Settings > Connections > Cellular Network > Call Forwarding. Test by calling your phone and letting it ring unanswered. Disable in the same menu when no longer needed.

Series 3 and later models support cellular via eSIM setup through the iPhone Watch app. Uses your iPhone's number by default but can be configured separately. Call via Siri, Contacts, or dial pad.

LTE models require eSIM activation through the Galaxy Wearable app. Shares your phone number or uses a separate one. Calling via Bixby, Contacts, or dial pad.

Manufacturers like TicWatch and Fossil implement similar cellular calling with minor interface differences. Consult device manuals for specifics.
