The Fenix 8 Pro Review: Integrated LTE and Orbital Communication for No-Phone Messaging

This most recent iteration of the flagship Fenix outdoor watch introduces a life-saving capability: phone-free messaging and SOS messaging via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating new mobile tech, plus an available advanced microLED screen in a special edition. It is Garmin's top model and designed to be the only gadget required to explore almost anywhere and monitor all your movements.

This makes it an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to 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.

Users get a lot of features for your money, with industry-leading workout, activity and outdoor monitoring. Its full offline maps of the globe can automatically direct you return to the trail if you lose your way absent a phone, and look excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an additional day of smartwatch battery life despite the display always active, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your mobile provider, like other smartwatches. But unlike Apple or Google's satellite-capable devices, SOS messaging is not provided for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE text and voice messages, call functionality and LiveTrack position tracking – so your friends or family can monitor you while engaged in running, biking or comparable pursuits – along with SOS satellite SOS alerts.

Location updates and messages via satellite are then billed additionally, with higher-tier subscriptions offering various allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have completed setup, you just head out the door minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable tasks, but you are able to make and take calls, dispatch texts and overall stay connected with your family and friends.

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

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is slow. It has a set of customisable pre-set replies you can use to expedite communication. Spoken messages and calls perform 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 set it up to on its own send a URL to selected contacts every time you start an exercise, so they can track your live position on a map. It’s great for monitoring competition progress, but it mostly acts as a tool for someone you rely on to be aware of your location in case something happens. It has generally worked well, although the actual location has occasionally lagged when moving in and out of strong LTE signal.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is essential to remember that satellite service is restricted to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with options offered through the support portal. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused components. Garmin offers recycling programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of coverage.

The result is an even more remarkable adventure device for those that desire to be unplugged. If you want to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to provide the service. Fortunately it is not dependent on your phone carrier so functions with all make of smartphone and network.

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

Advantages: LTE and orbital communication, high-luminance OLED display, monitors everything with premier GPS, integrated torch, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and satellite functions require ongoing payment, limited Garmin Pay financial compatibility, speech features are slow, limited wearable features compared with Apple/Google/Samsung watches.
