Garmin Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for Phone-Free Messaging

The most recent iteration of the top-tier Fenix outdoor watch brings a life-saving capability: phone-free communication and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new cellular technology, plus an available state-of-the-art microLED display in a special edition. It is Garmin's premier model and engineered to be the only gadget required to explore virtually any location and track all your movements.

That positions it as an very expensive option, 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 – almost twice the price of the standard Fenix 8.

Users receive a significant features for your money, with industry-leading workout, movement and adventure tracking. The complete offline mapping of the world can seamlessly guide you back 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 dimensions, not the more compact 43mm version found in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of smartwatch battery life despite the screen always active, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and orbital service plan instead of depending on a watch plan linked to your phone carrier, as with other smartwatches. However unlike Apple or Google's satellite-capable products, SOS communication is not provided for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while out running, biking or similar activities – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with more expensive subscriptions offering various allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you are able to make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via text or spoken messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable canned responses you can use to expedite communication. Voice messages and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to on its own send a URL to selected contacts every time you start an activity, so they can follow your real time position on a map. It’s excellent for monitoring competition performance, but it primarily serves as a tool for someone you rely on to know your whereabouts in case something happens. It has typically functioned well, though the actual position has occasionally been delayed when moving in and out of strong LTE signal.

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

A guide shows you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, though it is essential to note that orbital service is limited to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with services available via the support site. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital communication, location update and emergency SOS for when you’re without coverage.

The result is an increasingly remarkable adventure device for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach service to enable the service. At least it is not reliant on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, biking or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with premier GPS, integrated flashlight, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and orbital functions require ongoing subscription, restricted Garmin Pay financial support, voice capabilities are sluggish, limited wearable functionality versus competing watches.
