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

This most recent iteration of Garmin's premium Fenix outdoor timepiece includes a life-saving feature: no-phone messaging and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating new mobile tech, plus an available state-of-the-art microLED display in a special edition. This is the brand's top device and designed to be the only tool required to explore virtually anywhere and monitor every activity.

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

Users receive a significant functionality for your investment, with industry-leading fitness, activity and outdoor monitoring. Its complete offline mapping of the world can automatically direct you back to the trail if you get lost absent a phone, and look excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life even with the display on all the time, enduring 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 orbital subscription service instead of depending on a watch plan tied to your mobile provider, as with other smartwatches. But unlike competing satellite-capable devices, SOS communication is not provided for no cost.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can monitor you while out jogging, biking or similar activities – along with emergency orbital SOS messaging.

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

After you have completed setup, you just venture the door without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin dispatches 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 via typed or voice communications, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set responses you can use to speed things up. Spoken messages and calls perform OK, though as with most wearables, you’re not going to want to use it for extended discussions as the quality is less than ideal.

LiveTrack is the most useful function. You can set it up to automatically send a link to chosen contacts whenever you begin an exercise, so they can follow your live 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 worked well, although the real location has occasionally lagged when moving in and out of good 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 orbital activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance shows you how to locate the line of sight 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 vital lifeline, though it is important to remember that orbital coverage is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available via the support portal. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal schemes on new purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re without signal.

The result is an even more impressive adventure device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal price of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it is not dependent on your phone provider so works with any brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, built-in flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and satellite functions need ongoing payment, restricted Garmin Pay bank support, speech capabilities are sluggish, limited wearable features versus competing watches.
