The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for No-Phone Messaging

This newest version of Garmin's premium Fenix outdoor timepiece brings a life-saving feature: no-phone messaging and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile tech, along with an available state-of-the-art microLED display in a limited edition. It is the brand's top model and designed to be the single tool required to explore almost any location and track every activity.

That makes it an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the regular Fenix 8.

You do get a lot of features for your investment, with best-in-class workout, activity and outdoor tracking. The complete offline mapping of the world can automatically direct you return to the path if you lose your way without a phone, and appear great on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your mobile carrier, as with other wearables. But in contrast to competing satellite-enabled products, emergency messaging is not provided for free.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack location tracking – so your friends or family can monitor you while engaged in jogging, biking or similar activities – plus emergency satellite SOS messaging.

Location updates and messages via orbital are then billed additionally, with more expensive plans offering different quotas of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

After you have completed setup, you just venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you can make and take calls, dispatch texts and overall keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally via typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a mobile number is enough to register for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can use to expedite communication. Spoken messages and calls work OK, although as with most wearables, you’re not going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the most useful function. You can set it up to on its own send a link to chosen contacts whenever you start an activity, so they can track your real time location on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you rely on to be aware of your location in case something happens. It has generally functioned well, although the real position has sometimes lagged when moving in and out of good LTE signal.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, though it is essential to note that satellite service is restricted to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered via the support portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re without coverage.

The result is an even more remarkable adventure device for those that desire to be phone-free. If you wish to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

It is very freeing to be outside without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the features. At least it isn’t reliant on your phone carrier so functions with any brand of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, cycling or trekking, but still wants to be trackable and reachable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED display, tracks everything with best-in-class GPS, integrated flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: very expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay bank support, speech capabilities are sluggish, basic wearable functionality compared with Apple/Google/Samsung watches.
