Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

This newest version of Garmin's premium Fenix outdoor timepiece introduces a potentially lifesaving capability: phone-free communication and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED display in a limited edition. It is the brand's premier model and engineered to be the single tool required to explore almost anywhere 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 reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the cost of the regular Fenix 8.

You do receive a lot of functionality for your money, with best-in-class workout, movement and adventure monitoring. The complete offline mapping of the globe can automatically guide you back to the trail if you lose your way absent a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed boasts an additional day of watch battery life even with the display always active, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan linked to your mobile carrier, as with other smartwatches. But unlike competing satellite-enabled products, SOS messaging is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which includes unlimited LTE text and voice messages, calls and LiveTrack position tracking – so your contacts or family can monitor you while out running, cycling or comparable pursuits – along with SOS orbital SOS messaging.

Location updates and messages over orbital are then billed on top, with more expensive plans offering different allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you simply head out outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can make and take calls, dispatch texts and overall keep in touch with your relatives and friends.

When you text someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via typed or spoken messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set responses you can send to speed things up. Spoken messages and calls perform OK, although as with the majority of wearables, you’re not going to want to use it for lengthy discussions as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to chosen contacts whenever you begin an exercise, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you trust to be aware of your whereabouts in case something happens. It has generally worked effectively, though the actual location has occasionally lagged when moving in and out of good LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A on-screen assistance shows you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is important to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options offered via the customer service site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused materials. Garmin offers recycling schemes on recent purchases.

Cost

The Fenix 8 Pro is priced 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

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor device for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without requiring additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it isn’t 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 hates being burdened by their phone when jogging, biking or hiking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks all activities with premier GPS, built-in flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and orbital functions need monthly payment, limited Garmin Pay financial compatibility, speech features are slow, limited wearable functionality versus competing watches.
