The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Texting

This newest version of Garmin's premium Fenix outdoor timepiece includes a potentially lifesaving capability: no-phone messaging and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new cellular tech, along with an available advanced microLED display in a limited edition. This is the brand's premier model and designed to be the single tool needed to explore virtually any location and monitor every activity.

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

Users receive a lot of functionality for your investment, with industry-leading workout, movement and adventure tracking. The complete offline mapping of the world can seamlessly direct you back to the path if you get lost absent a phone, and appear excellent on the large, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. But unlike Apple or Google's satellite-enabled products, SOS communication is not included for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE text and voice messages, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or similar pursuits – along with SOS orbital SOS messaging.

Check-ins and texts over orbital are then charged on top, with higher-tier plans including different allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the service.

Once you have got it set up, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable tasks, but you can 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 arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using typed or spoken messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It has a set of customisable canned replies you can send to speed things up. Spoken recordings and calls work OK, though as with most wearables, you’re not going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to chosen contacts whenever you start an activity, so they can track your real time location on a map. It’s great for monitoring race progress, but it mostly serves as a utility for someone you trust to know your whereabouts in case something happens. It has typically worked well, though the real position has occasionally lagged when transitioning in and out of good LTE signal.

All of these features are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is essential to note that satellite coverage is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered through the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused materials. Garmin offers recycling schemes on recent purchases.

Cost

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re out of coverage.

The result is an even more impressive outdoor tool for those that want 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 accomplishes this without requiring additional gear.

It is quite liberating to be outside without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the service. At least it is not reliant on your phone provider so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, biking or hiking, but still wants to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED display, tracks 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, buttons and touch.

Drawbacks: very expensive, LTE and satellite functions need monthly payment, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, basic wearable functionality versus competing watches.
