The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Messaging

This latest iteration of the premium Fenix adventure timepiece brings a life-saving capability: phone-free messaging and emergency messaging via 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an optional advanced microLED display in a special edition. This is Garmin's premier model and engineered to be the only tool needed to venture virtually anywhere and monitor all your movements.

This positions it as an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the cost of the regular Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading fitness, movement and outdoor tracking. The complete offline mapping of the globe can automatically guide you back to the path if you get lost absent a phone, and appear great on the large, crisp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other models, so it is a big watch for larger wrists. But the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the screen on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your mobile carrier, as with other wearables. However in contrast to Apple or Google's satellite-enabled devices, emergency messaging is not provided for free.

Instead, subscriptions start at £7.99 or equivalent a month, which includes limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can keep an eye on you while engaged in running, cycling or comparable activities – along with SOS satellite SOS messaging.

Location updates and messages via satellite are then billed on top, with higher-tier plans including different quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial 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 streaming music or similar tasks, but you can 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 random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally via text or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is slow. It has a collection of personalizable canned responses you can send to speed things up. Voice recordings and calls work OK, although as with the majority of smartwatches, you’re not going to want to use it for lengthy discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a link to selected contacts every time you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it mostly acts as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked well, although the real position has sometimes lagged when transitioning in and out of good LTE coverage.

All of these features are available on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then transmits and gets messages 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 satellite coverage is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered through the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling schemes on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service 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 messaging, call functionality and LiveTrack – along with orbital communication, location update and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive adventure device for those that desire to be phone-free. If you want to have someone monitor you remotely while running out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to enable the features. At least it is not dependent on your phone provider so functions with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still wants to be trackable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite messaging, high-luminance OLED display, monitors all activities with premier GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: very costly, LTE and satellite functions require monthly subscription, limited Garmin Pay bank compatibility, speech features are slow, basic smartwatch features versus competing watches.
