The main difference between an Apple Watch with GPS and an Apple Watch with GPS and cellular capabilities lies in their connectivity options.
An Apple Watch with GPS can connect to your iPhone's GPS to track your location, distance, and speed during workouts or outdoor activities. It relies on the paired iPhone for internet access, as it doesn't have its own cellular capability. This means that to use features like receiving calls, texts, or streaming music, your iPhone needs to be within range.
On the other hand, an Apple Watch with GPS and cellular has an additional cellular modem built into it. This allows the watch to connect directly to cellular networks without requiring the presence of an iPhone nearby. With cellular connectivity, you can make and receive calls, send and receive messages, stream music, and access many internet-based functions even when your iPhone is not in close proximity.
The cellular feature adds an extra layer of convenience, as you can stay connected and use various watch functions independently. However, it's important to note that cellular connectivity may require an additional data plan or carrier support, which could incur additional costs.
Ultimately, the choice between an Apple Watch with GPS or GPS and cellular comes down to your individual needs and preferences. If you frequently rely on your iPhone and don't often find yourself without it, the GPS-only version might be sufficient. However, if you desire the freedom of using your Apple Watch independently or want the added convenience of cellular connectivity, opting for the GPS and cellular model can provide a more seamless user experience.
