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

This latest iteration of Garmin's top-tier Fenix adventure watch includes a life-saving feature: phone-free communication and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge mobile tech, along with an available state-of-the-art microLED display in a limited edition. It is Garmin's premier device and engineered to be the only gadget required to venture almost anywhere and track all your movements.

This positions it as an extremely expensive option, starting at £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 price of the standard Fenix 8.

Users receive a significant functionality for your money, with best-in-class workout, activity and adventure monitoring. The full offline maps of the world can automatically direct you back to the path if you lose your way without a phone, and look excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as tested boasts an additional day of watch battery life despite the display always active, lasting a solid eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your phone carrier, like other wearables. But unlike competing satellite-capable devices, emergency messaging is not included for free.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, calls and LiveTrack position tracking – so your contacts or family can monitor you while out jogging, biking or comparable pursuits – along with emergency satellite SOS messaging.

Check-ins and messages over satellite are then billed on top, with more expensive subscriptions offering various quotas of orbital usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the service.

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

When you text someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then message back and forth via typed or spoken communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can use to speed things up. Spoken messages and calls work OK, although as with most wearables, you’re unlikely going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to selected contacts every time you begin an activity, so they can follow your live location on a map. It’s excellent for following competition performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case something happens. It has generally worked effectively, though the real position has sometimes lagged when transitioning in and out of good LTE signal.

These features are available on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide shows you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to note that satellite service is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services available through the support site. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin provides recycling schemes on new purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without coverage.

Outcome is an increasingly remarkable 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 middle of nowhere, the Garmin does so without requiring additional gear.

It is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to provide the features. Fortunately it is not dependent on your phone carrier so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be trackable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, tracks everything with premier GPS, integrated torch, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and orbital functions require monthly payment, limited Garmin Pay financial compatibility, voice capabilities are sluggish, basic wearable features versus competing watches.
