The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Messaging

This newest model of Garmin's flagship Fenix outdoor watch includes a life-saving feature: no-phone communication and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new mobile technology, along with an optional state-of-the-art microLED screen in a limited edition. It is Garmin's premier model and designed to be the only tool required to venture almost anywhere and track every activity.

This makes it an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the standard Fenix 8.

You do get a significant features for your investment, with best-in-class workout, activity and outdoor tracking. Its complete offline mapping of the world can seamlessly guide you return to the trail if you get lost absent a phone, and look excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a large watch for larger wrists. But the 47mm OLED version as tested boasts an additional day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription service instead of relying on a watch plan linked to your mobile carrier, like other wearables. However in contrast to Apple or Google's satellite-capable devices, emergency messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while engaged in jogging, cycling or comparable pursuits – plus SOS satellite SOS alerts.

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

After you have completed setup, you just head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your family and friends.

When you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via typed or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a mobile number is sufficient 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 collection of personalizable canned responses you can use to expedite communication. Voice messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can set it up to on its own send a link to chosen contacts whenever you begin an activity, so they can follow your live position on a map. It’s excellent for following race progress, but it primarily serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned well, though the actual position has sometimes lagged when transitioning in and out of strong LTE signal.

All of these features are available 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 transmit texts, location updates and SOS SOS.

A guide shows you how to find the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, though it is important to note that orbital coverage is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally repairable with services available through the customer service site. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused components. Garmin provides recycling schemes on recent purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

Outcome is an increasingly remarkable outdoor tool for those that want to be unplugged. If you want to have someone monitor you remotely while running out at night or in the remote areas, the Garmin does so without needing anything else.

This is very liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it is not reliant on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks all activities with premier GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: very costly, LTE and orbital features need ongoing payment, limited Garmin Pay bank compatibility, speech features are sluggish, limited wearable features compared with Apple/Google/Samsung watches.
