The Fenix 8 Pro Analysis: Integrated LTE and Orbital Connectivity for Phone-Free Texting

This newest model of the top-tier Fenix outdoor timepiece includes a potentially lifesaving capability: phone-free communication and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an available advanced microLED screen in a special edition. This is Garmin's top device and designed to be the single tool needed to explore virtually any location and track all your movements.

This makes it an extremely expensive proposition, priced from £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 cost of the regular Fenix 8.

Users receive a significant features for your money, with industry-leading workout, activity and adventure monitoring. The complete offline mapping of the world can seamlessly guide you return to the path if you get lost absent a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed does have an additional day of watch battery life despite the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan tied to your phone carrier, like other smartwatches. But unlike competing satellite-enabled products, SOS messaging is not included for free.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messages, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out jogging, biking or similar pursuits – along with emergency satellite SOS alerts.

Check-ins and messages over satellite are then charged on top, with higher-tier plans including various quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

Once you have completed setup, you just venture outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you can make and take calls, dispatch texts and overall stay connected with your family and friends.

When you message 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 app, you can then message back and forth via typed or voice 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 enough to register for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set replies you can use to expedite communication. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to chosen contacts whenever you start an activity, so they can follow your real time position on a map. It’s excellent for following competition performance, but it mostly acts as a tool for someone you rely on to know your location in case an incident occurs. It has typically functioned effectively, although the real location has sometimes lagged when moving in and out of good LTE signal.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide displays you how to find the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is important to remember that orbital coverage is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options offered through the customer service portal. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch lacks any recycled components. 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 plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital 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 unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the service. At least it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, biking or trekking, but still wants to be trackable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED screen, tracks everything with best-in-class GPS, integrated torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and orbital features need monthly subscription, restricted Garmin Pay financial compatibility, voice capabilities are slow, limited smartwatch features versus competing watches.
