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

The latest model of the premium Fenix outdoor timepiece brings a potentially lifesaving feature: no-phone communication and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new cellular tech, plus an available state-of-the-art microLED display in a limited edition. This is the brand's top device and designed to be the only gadget required to venture almost any location and track all your movements.

That makes it an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the regular Fenix 8.

You do get a lot of features for your money, with best-in-class workout, activity and adventure monitoring. Its full offline mapping of the world can seamlessly direct you return to the trail if you lose your way absent a phone, and look great on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an extra day of watch battery life even with the screen always active, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your phone carrier, like other wearables. But unlike Apple or Google's satellite-enabled devices, emergency messaging is not included for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, calls and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, biking or comparable pursuits – along with SOS satellite SOS alerts.

Check-ins and messages over satellite are then billed on top, with more expensive subscriptions including different quotas of satellite usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to make and take calls, send texts and generally keep in touch with your relatives and companions.

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

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set replies you can send to expedite communication. Spoken recordings and calls work OK, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can configure to on its own send a URL to selected contacts every time you start an exercise, so they can follow your live location on a map. It’s excellent for monitoring competition performance, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has typically worked effectively, though the actual location has occasionally been delayed when transitioning in and out of good LTE coverage.

These capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide shows you how to find the clear view 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 crucial safety feature, however it is important to remember that orbital coverage is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with options offered through the support portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin offers disposal programs on recent purchases.

Cost

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

Conclusion

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive adventure tool for those that desire to be phone-free. If you wish to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is very freeing to be outdoors without a phone, but that functionality carries a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the service. At least it is not reliant on your phone provider so works with any brand of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but still wants to be trackable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED screen, monitors all activities with premier GPS, built-in flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and orbital features need ongoing subscription, restricted Garmin Pay financial support, speech features are sluggish, limited wearable functionality compared with competing watches.
