The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Texting

This most recent iteration of the flagship Fenix adventure watch introduces a life-saving capability: phone-free communication and SOS alerts using 4G LTE or satellite connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding new mobile tech, plus an available advanced microLED display in a special edition. It is Garmin's top device and designed to be the only gadget needed to explore virtually any location and monitor every activity.

That positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the cost of the standard Fenix 8.

Users receive a lot of features for your investment, with best-in-class fitness, movement and adventure monitoring. Its complete offline mapping of the globe can seamlessly direct you back to the trail if you get lost without a phone, and appear great on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your mobile carrier, like other wearables. However unlike Apple or Google's satellite-enabled products, SOS messaging is not included for no cost.

Instead, plans start at £7.99 or equivalent a month, which provides limitless LTE text and audio messaging, calls and LiveTrack position tracking – so your friends or family can keep an eye on you while out jogging, biking or similar pursuits – along with emergency orbital SOS alerts.

Check-ins and messages via orbital are then charged additionally, with higher-tier plans including different quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, dispatch texts and generally stay connected with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via text or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable pre-set replies you can send to speed things up. Spoken recordings and calls work OK, although as with most smartwatches, you’re unlikely going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a URL to chosen contacts whenever you begin an activity, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you trust to be aware of your location in case something happens. It has typically worked effectively, although the real position has occasionally lagged when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is essential to remember that satellite coverage is restricted to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with services available via the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal schemes on recent purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor device for those that desire to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the remote areas, the Garmin accomplishes this without requiring anything else.

It is quite freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal price of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone provider so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but still desires to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED display, tracks everything with best-in-class GPS, built-in torch, voice and offline commands, 8+ day battery life, Garmin Pay, full offline maps and routes, 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, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
