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

The newest model of Garmin's flagship Fenix adventure timepiece brings a life-saving capability: no-phone messaging and emergency alerts via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding new mobile tech, plus an optional state-of-the-art microLED display in a special edition. It is the brand's top model and engineered to be the single tool needed to explore virtually any location and monitor all your movements.

That positions it as an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the standard Fenix 8.

You do get a significant functionality for your money, with best-in-class fitness, movement and adventure monitoring. The full offline maps of the globe can automatically guide you return to the trail if you get lost without a phone, and look great on the sizable, sharp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other models, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life despite the screen on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your mobile provider, like other smartwatches. However unlike competing satellite-enabled devices, emergency messaging is not included for free.

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack position tracking – so your friends or family can monitor you while out running, cycling or comparable pursuits – plus emergency satellite SOS alerts.

Check-ins and texts via orbital are then charged on top, with more expensive subscriptions offering different allowances of orbital usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

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 playing music or comparable activities, but you are able to place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using text or spoken messages, and make voice calls. Your recipient 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 works fine but typing out texts on the tiny on-screen keyboard is slow. It has a set of customisable canned replies you can use to speed things up. Spoken recordings and calls perform acceptably, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a link to chosen contacts whenever you start an activity, so they can track your real time position on a map. It’s great for following competition progress, but it mostly serves as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally worked well, although the real location has occasionally lagged when moving in and out of good LTE coverage.

These features are available on other Garmin devices if you bring 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 guide 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 easy to use and could be a crucial lifeline, however it is important to note that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available via the support portal. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on recent purchases.

Cost

This 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).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable outdoor device for those that desire to be phone-free. If you wish to have someone monitor you from afar while running out at night or in the remote areas, the Garmin does so without needing anything else.

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 works with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, cycling or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED screen, monitors all activities with premier GPS, integrated torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and orbital functions need monthly subscription, restricted Garmin Pay bank support, speech capabilities are sluggish, basic smartwatch functionality compared with competing watches.
