Makes calls from your wrist; Voice control is excellent; A joy to use; Masses of personalization options; Superb fitness tracking ability

Third-party app support is lacking; Expensive; Speaker is quiet

A genuine gadget marvel, but its 4G smarts just need a little longer in the tech oven

Incredibly small for a 4G smartwatch; Still the best fitness tracker around; Voice calls work surprisingly well; Battery life holds up; even when using 4G; Huge array of bands means you can make it your own

Only available on one carrier in the UK; Apple Music streaming not yet available on 4G; Not all apps work on 4G without your phone; You still need an iPhone to use it; Overkill if you mainly want fitness tracking

It's not easy to thoughtfully integrate cellular and LTE service on a wearable. A number of Android Wear devices have tried in the past, and none of them hit home runs. In my short time with the Apple Watch Series 3 with LTE, it's clear that Apple has the software chops to make cellular and LTE a...

Battery life can stand up to some LTE use; Audible Siri responses make hands-free; eyes-free Watch interactions easy; Improved performance thanks to S3 dual-core processor

Why the red dot? Why; LTE models require additional monthly charges by wireless service providers; Quite expensive even before extra monthly wireless charges; Standalone LTE can be unreliable; No on-Watch toggles to disconnect Wi-Fi and Bluetooth manually

The Apple Watch Series 3 with cellular takes a major step forward in making Apple's wrist-worn device its own independent, connected computing platform. Simply put, it's a must-have for athletes in the Apple ecosystem, and a wearable device worth considering for many other non-fitness use cases.

Initially, the pacing was ferocious, as a slew of companies were quick to deliver their offerings to our wrists, but as time wore in, we all soon realized that we're still constantly favoring our mobile devices as our go-to portal for connectivity. Through it all, though, the Apple Watch has remained the most relevant, with only a handful of others trying to keep pace – and that's despite the slowed interest in the segment as a whole!The Apple Watch Series 3 introduces one major feature that aims to break the bond that has kept it tethered to its master, the iPhone. Now that true cellular connectivity is on board with the Apple Watch Series 3, is that, along with some other new features, enough to spark renewed interest? It's a tough ma...

Expensive; LTE drains battery rapidly

The Apple Watch is now in its third year, so is it third time's a charm, or just more of the same?

Still requires phone to be helpful (this is not the Cellular version; Expensive; Always looks like a smartwatch; Not terribly durable

But that's not a typical use case. When jumping between phone and LTE connection as most people will do, I was easily able to make it through a full day. With the exception of making calls and listening to music, I measure my Apple Watch interactions in seconds, not minutes, but even when using it...

LTE gives Apple Watch the freedom it's always deserved; Incredibly fast chip and excellent battery life; Great health and fitness features

Some connectivity issues; No onboard App Store
