Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for No-Phone Texting

The latest model of Garmin's flagship Fenix outdoor timepiece introduces a potentially lifesaving capability: phone-free messaging and emergency alerts via 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new cellular tech, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier device and designed to be the only gadget needed to venture virtually anywhere and monitor all your movements.

This positions it as an extremely pricey option, starting at £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 edition with microLED screen – nearly twice the cost of the standard Fenix 8.

You do get a significant functionality for your investment, with best-in-class fitness, activity and adventure monitoring. Its full offline mapping of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and appear great on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life despite the display on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription plan instead of depending on a watch plan tied to your mobile carrier, as with other wearables. But unlike competing satellite-enabled devices, emergency communication is not provided for no cost.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE SMS and voice messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in jogging, cycling or similar activities – along with SOS orbital SOS alerts.

Check-ins and messages over satellite are then billed on top, with higher-tier plans offering different quotas of orbital usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you just venture outside without your phone and the watch will connect to LTE. You can not use it for playing music or similar activities, but you can place and receive calls, dispatch texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using text or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable canned responses you can use to speed things up. Voice messages and calls perform OK, although as with most wearables, you’re unlikely going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest feature. You can set it up to on its own transmit a link to chosen contacts whenever you begin an exercise, so they can follow your real time position on a map. It’s excellent for following competition progress, but it primarily acts as a tool for someone you trust to know your location in case an incident occurs. It has generally functioned effectively, though the real position has occasionally lagged when moving in and out of strong LTE signal.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance shows you how to find the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is important to remember that satellite service is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with services offered via the customer service portal. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any reused components. Garmin offers recycling programs on new purchases.

Price

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re without coverage.

Outcome is an even more impressive outdoor device for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial price of the watch and the monthly fee of the inReach service to enable the service. Fortunately it is not reliant on your phone carrier so functions with all 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 reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, monitors everything with best-in-class GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: very expensive, LTE and orbital features require ongoing subscription, limited Garmin Pay bank support, voice features are slow, basic wearable features versus competing watches.
