Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

This latest version of the premium Fenix adventure timepiece introduces a potentially lifesaving capability: phone-free messaging and emergency messaging via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, along with an available advanced microLED screen in a limited edition. This is Garmin's premier device and designed to be the only tool required to explore virtually anywhere and monitor every activity.

This makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the price of the standard Fenix 8.

Users get a significant functionality for your money, with industry-leading workout, activity and adventure tracking. Its full offline mapping of the world can seamlessly guide you return to the trail if you get lost absent a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the smaller 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of watch battery life despite the screen on all the time, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your phone carrier, like other smartwatches. However unlike Apple or Google's satellite-capable products, SOS communication is not included for free.

Instead, plans begin from £7.99 or similar a month, which provides limitless LTE SMS and audio messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in running, biking or similar pursuits – along with emergency satellite SOS alerts.

Location updates and texts over satellite are then billed additionally, with higher-tier plans offering various allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the functionality.

After you have completed setup, you just head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, send texts and overall stay connected with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then message back and forth using typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, just a mobile number is enough to register for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned responses you can send to speed things up. Spoken messages and calls perform acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for lengthy discussions as the quality is not fantastic.

LiveTrack is the most useful function. You can configure to on its own send a link to selected contacts whenever you start an activity, so they can follow your real time location on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you trust to know your location in case an incident occurs. It has generally worked well, though the actual location has sometimes lagged when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance displays you how to find the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is essential to remember that orbital service is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available via the customer service site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled materials. Garmin offers recycling programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly impressive outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach service to provide the features. Fortunately it isn’t dependent on your phone provider so works with any make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, cycling or trekking, but nevertheless desires to be trackable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with premier GPS, integrated flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and orbital features require ongoing subscription, limited Garmin Pay bank support, speech capabilities are sluggish, basic smartwatch features compared with Apple/Google/Samsung watches.
