Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Texting

This most recent model of the top-tier Fenix adventure watch introduces a life-saving capability: no-phone messaging and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new mobile tech, plus an optional state-of-the-art microLED screen in a limited edition. It is the brand's premier model and engineered to be the only tool needed to explore virtually any location and monitor all your movements.

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

You do get a lot of features for your investment, with best-in-class fitness, movement and adventure monitoring. The complete offline mapping of the globe can automatically guide you return to the path if you lose your way absent a phone, and look great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of smartwatch battery life despite the screen always active, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and orbital subscription service instead of relying on a watch plan linked to your mobile carrier, as with other wearables. But unlike Apple or Google's satellite-capable devices, emergency messaging is not included for free.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your contacts or loved ones can monitor you while out running, biking or similar activities – plus emergency orbital SOS messaging.

Location updates and messages via satellite are then charged on top, with higher-tier subscriptions including different quotas of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the service.

After you have completed setup, you just head out outside minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you are able to place and receive calls, dispatch texts and generally stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally using typed or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a phone number is sufficient to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to speed things up. Spoken recordings and calls perform OK, though as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to selected contacts whenever you begin an activity, so they can follow your real time position on a map. It’s excellent for monitoring race performance, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned well, though the real position has occasionally lagged when moving in and out of strong LTE signal.

All of these capabilities are available on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, however it is essential to note that satellite service is limited to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with services available via the support site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin provides recycling schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re out of signal.

The result is an increasingly remarkable adventure tool for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin does so without needing additional gear.

It is very liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the features. At least it isn’t dependent on your phone provider so functions with any brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, biking or hiking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors all activities with premier GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital features need monthly subscription, limited Garmin Pay bank compatibility, voice features are sluggish, limited smartwatch features compared with Apple/Google/Samsung watches.
