The Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for Phone-Free Texting

The newest iteration of Garmin's premium Fenix adventure watch includes a life-saving capability: phone-free communication and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding cutting-edge mobile technology, along with an optional advanced microLED display in a limited edition. This is the brand's premier model and designed to be the only tool needed to explore almost any location and track all your movements.

This makes it an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

Users receive a lot of functionality for your investment, with industry-leading workout, activity and adventure tracking. Its full offline maps of the world can seamlessly direct you return to the trail if you get lost without a phone, and appear great on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan linked to your mobile carrier, like other wearables. However in contrast to competing satellite-enabled products, emergency messaging is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and voice messages, calls and LiveTrack location tracking – so your contacts or loved ones can monitor you while engaged in running, biking or similar activities – along with emergency satellite SOS messaging.

Location updates and texts over orbital are then billed on top, with more expensive subscriptions including various quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the functionality.

After you have got it set up, you simply head out outside minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, send texts and overall keep in touch with your family and companions.

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

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable pre-set responses you can send to expedite communication. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a link to selected contacts every time you begin an activity, so they can track your live position on a map. It’s great for monitoring competition progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned effectively, though the actual location has occasionally lagged when moving in and out of good LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance shows you how to find 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 crucial lifeline, however it is essential to remember that satellite coverage is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options available via the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal schemes on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable outdoor tool for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

This is quite freeing to be outside without a phone, but that capability carries a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the features. At least it isn’t dependent on your phone provider so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but nevertheless desires to be trackable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated torch, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Cons: extremely expensive, LTE and satellite functions need ongoing payment, limited Garmin Pay bank support, speech features are sluggish, limited smartwatch functionality versus competing watches.
