The Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for Phone-Free Messaging

This newest iteration of the top-tier Fenix outdoor timepiece includes a life-saving feature: no-phone messaging and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, plus an optional advanced microLED screen in a special edition. This is the brand's premier device and engineered to be the only tool needed to venture almost any location and monitor every activity.

This makes it an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the standard Fenix 8.

You do get a significant features for your investment, with best-in-class fitness, movement and adventure monitoring. Its complete offline mapping of the globe can automatically direct you back to the path if you get lost without a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as tested boasts an extra day of watch battery life even with the screen always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan linked to your mobile provider, as with other smartwatches. However unlike Apple or Google's satellite-capable devices, SOS messaging is not provided for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messages, calls and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while out running, biking or similar activities – plus emergency orbital SOS messaging.

Check-ins and messages via orbital are then charged additionally, with higher-tier plans offering various allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

After you have completed setup, you simply venture the door without your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or spoken communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can use to speed things up. Spoken recordings and calls work acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a link to chosen contacts whenever you start an activity, so they can track your live position on a map. It’s excellent for following race performance, but it mostly acts as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked effectively, although the actual position has occasionally lagged when transitioning in and out of good LTE coverage.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance shows you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to remember that orbital service is restricted to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available through the customer service portal. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal programs on new purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly remarkable adventure device for those that desire to be unplugged. If you want to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin does so without needing anything else.

It is very liberating to be outside without a phone, but that functionality carries quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it is not reliant on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED display, tracks everything with premier GPS, integrated flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite features require monthly payment, restricted Garmin Pay bank compatibility, voice features are sluggish, limited wearable functionality compared with Apple/Google/Samsung watches.
