The Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for Phone-Free Messaging

The most recent model of the premium Fenix outdoor watch introduces a potentially lifesaving feature: no-phone communication and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED screen in a limited edition. It is Garmin's premier device and engineered to be the single gadget required to venture almost any location and track all your movements.

This positions it as an extremely expensive proposition, starting at £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 – almost twice the price of the standard Fenix 8.

You do get a significant functionality for your investment, with best-in-class fitness, activity and adventure tracking. Its full offline maps of the globe can seamlessly direct you return to the trail if you lose your way absent a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the smaller 43mm version available in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life despite the display on all the time, lasting 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 tied to your phone carrier, as with other smartwatches. However unlike competing satellite-enabled products, SOS communication is not included for no cost.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE SMS and voice messages, call functionality and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while engaged in running, biking or similar activities – along with emergency satellite SOS alerts.

Location updates and texts over satellite are then billed on top, with more expensive subscriptions including different quotas of orbital usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the functionality.

After you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for streaming 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.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via text or spoken communications, and make voice calls. Your contact does not need a Garmin profile 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 slow. It has a collection of customisable pre-set replies you can send to expedite communication. Spoken messages and calls work OK, although as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a link to chosen contacts whenever you begin an activity, so they can track your live location on a map. It’s great for following race progress, but it primarily acts as a tool for someone you trust to be aware of your location in case an incident occurs. It has generally functioned well, though the actual position has sometimes lagged when transitioning in and out of strong LTE signal.

These capabilities are available 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 send texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to note that orbital coverage is limited to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options offered via the support site. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused materials. Garmin offers recycling schemes on recent purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly impressive outdoor device for those that want 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 anything else.

This is very liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to provide the service. 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 device for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks everything with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: extremely costly, LTE and orbital functions require monthly subscription, restricted Garmin Pay financial support, voice features are slow, limited smartwatch features versus competing watches.
