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

The most recent iteration of Garmin's flagship Fenix outdoor watch includes a potentially lifesaving feature: no-phone communication and SOS alerts using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new cellular tech, plus an optional advanced microLED display in a special edition. This is Garmin's premier model and engineered to be the single tool needed to explore almost anywhere and monitor every activity.

That positions it as an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the cost of the standard Fenix 8.

Users get a significant functionality for your money, with best-in-class fitness, movement and outdoor monitoring. Its complete offline mapping of the world can automatically guide you back to the trail if you get lost without a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as tested does have an extra day of watch battery life despite the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite subscription service instead of depending on a watch plan linked to your phone provider, as with other wearables. But in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not provided for free.

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

Location updates and texts over orbital are then charged on top, with more expensive subscriptions including various allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You can not use it for playing music or similar activities, but you are able to place and receive 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 phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally using typed or voice messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned replies you can send to speed things up. Spoken messages and calls work OK, though 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 ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to chosen contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for following race progress, but it mostly serves as a utility for someone you rely on to know your location in case something happens. It has typically worked well, though the real position has sometimes been delayed when moving in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then sends and receives messages 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 continent, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered via the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused components. Garmin offers recycling schemes on recent purchases.

Price

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).

Verdict

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

The result is an even more remarkable outdoor tool for those that want to be phone-free. If you want 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.

It is very liberating to be outdoors without a phone, but that capability carries a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to enable the service. Fortunately it is not reliant on your phone provider so works with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors all activities with premier GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and orbital features require monthly subscription, restricted Garmin Pay financial support, voice capabilities are sluggish, limited smartwatch features compared with Apple/Google/Samsung watches.
