Can a Smartwatch Make Calls Without a Phone?

Smartwatches have become increasingly popular as wearable devices that offer a range of functionalities. One of the key features users often seek in a smartwatch is the ability to make calls without relying on a smartphone. In this article, we will delve into the world of standalone calling features on smartwatches and explore their feasibility, benefits, limitations, and the future of this technology.

With standalone connectivity options available, smartwatches have evolved beyond being mere smartphone companions. Users can now enjoy the convenience of making and receiving calls directly from their wrists, without the need for a smartphone nearby. This article aims to provide you with a comprehensive understanding of standalone calling on smartwatches and help you make an informed decision.

Understanding Smartwatch Connectivity

Smartwatches offer different connectivity options, which can broadly be categorized into tethered connectivity and standalone connectivity. Tethered connectivity involves pairing the smartwatch with a smartphone, while standalone connectivity allows the smartwatch to function independently.

Tethered connectivity enables users to utilize their smartwatches as an extension of their smartphones. This means that calls made or received on the smartwatch are routed through the paired smartphone. On the other hand, standalone connectivity eliminates the dependence on a smartphone, enabling direct calling capabilities from the smartwatch itself.

Both options come with their own set of advantages and disadvantages. Tethered connectivity ensures a seamless integration between the smartphone and smartwatch, but it requires the smartphone to be in close proximity. Standalone connectivity offers greater freedom and convenience, but it may have limitations in terms of network compatibility and additional costs.

Standalone Calling Features of Smartwatches

Standalone calling on smartwatches involves the integration of cellular connectivity directly into the device. This allows the smartwatch to have its own SIM card and phone number, enabling independent calling functionality. However, not all smartwatches support standalone calling, and compatibility with wireless carriers and networks should be considered.

The availability of standalone calling features depends on the smartwatch model and its support for cellular connectivity. Some smartwatches come equipped with 4G/LTE capabilities, while others may only support 3G or rely on Bluetooth tethering for calls. Understanding the specifications and limitations of standalone calling on different smartwatches is crucial for making an informed decision.

Popular Smartwatches with Standalone Calling

Several smartwatch brands offer models with standalone calling features. For instance, the Apple Watch Series 7, Samsung Galaxy Watch, and Fitbit Versa series are well-known options that provide standalone connectivity. These smartwatches often offer a range of features beyond standalone calling, including messaging integration, GPS functionality, and health tracking capabilities.

When choosing a smartwatch for standalone calling, it’s essential to compare the features, compatibility, and limitations of different models. Factors such as battery life, call quality, and software integration should also be considered to ensure a satisfactory user experience.

Setting Up and Making Calls on a Smartwatch

Setting up a smartwatch for standalone calling involves a series of steps that may vary depending on the model and operating system. Generally, it includes inserting a compatible SIM card, configuring network settings, and ensuring that the smartwatch is activated for standalone calling.

Once the setup is complete, making calls from a smartwatch is usually as simple as accessing the dialer app or using voice commands. Some smartwatches support voice assistants like Siri or Google Assistant, allowing users to initiate calls by voice alone. Call quality may vary depending on the smartwatch’s hardware and network connectivity.

Additional Features and Benefits

Smartwatches with standalone calling capabilities often offer additional features that enhance the user experience. These include integration with messaging apps, allowing users to send and receive texts directly from their smartwatches, and the ability to receive notifications and alerts conveniently on the wrist. This integration with messaging apps ensures that users can stay connected and respond to important messages without needing their smartphones.

Moreover, standalone smartwatches often come equipped with GPS functionality, enabling users to navigate and receive turn-by-turn directions directly on their wrists. This feature can be particularly useful during outdoor activities, exercise routines, or when exploring new places.

Another significant benefit of standalone smartwatches is their fitness tracking and health monitoring capabilities. Many models offer built-in sensors to track various health metrics such as heart rate, sleep patterns, steps taken, and calories burned. These features allow users to maintain an active and healthy lifestyle by monitoring their fitness progress conveniently from their smartwatches.

Limitations and Considerations

While standalone calling on smartwatches brings convenience and freedom, there are certain limitations and considerations to keep in mind. One crucial factor is the battery life of the smartwatch. Standalone calling can consume more power compared to basic smartwatch functions, affecting the overall battery performance. Users should ensure their smartwatches have sufficient battery capacity to support standalone calling throughout the day.

Additionally, network coverage and signal strength play a vital role in the quality of standalone calls. Users must consider their location and the network coverage provided by their wireless carrier. Poor signal reception can result in dropped calls or reduced call quality, affecting the overall calling experience.

Privacy and security concerns are also important considerations. Smartwatches with standalone calling capabilities store personal information and have their own phone numbers. Users should ensure that their smartwatches have adequate security measures in place to protect their data and prevent unauthorized access.

Compatibility with different operating systems is another consideration. Smartwatches may be designed to work seamlessly with specific operating systems, such as watchOS for Apple Watches or Wear OS for Android-based smartwatches. Users should check the compatibility of their smartwatch with their preferred operating system to ensure a smooth and integrated user experience.

Future Trends and Developments

The world of smartwatches is continuously evolving, and advancements in standalone calling technology are expected. Manufacturers are working towards improving battery efficiency, expanding network compatibility, and enhancing overall performance. Future smartwatches may offer even more seamless standalone calling experiences, with improved call quality and expanded network support.

Moreover, the integration of emerging communication technologies, such as 5G, may open up new possibilities for standalone calling on smartwatches. Faster data speeds and lower latency can enhance the overall calling experience, enabling clearer voice calls and faster data transfers.

As the demand for standalone calling features on smartwatches continues to grow, manufacturers will likely invest in research and development to meet consumer expectations. This investment is expected to drive further innovations in standalone smartwatch technology, making them even more capable and versatile communication devices.


In conclusion, standalone calling on smartwatches provides users with the freedom to make and receive calls without relying on a smartphone. With the advancements in cellular connectivity and the integration of calling features, standalone smartwatches offer convenience, enhanced connectivity, and additional functionalities.

While standalone calling has its limitations and considerations, it offers a promising future for smartwatches as independent communication devices. As technology continues to evolve, we can expect further improvements, expanded network support, and enhanced user experiences.

Whether you’re looking for the convenience of leaving your smartphone behind or seeking a seamless calling experience, standalone smartwatches provide a viable solution. By understanding the features, limitations, and considerations outlined in this article, you can make an informed decision and find a smartwatch that suits your communication needs. Embrace the freedom of standalone calling and unlock the full potential of your smartwatch.
