The Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Messaging

The most recent version of Garmin's premium Fenix adventure watch includes a potentially lifesaving capability: no-phone communication and emergency alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an available advanced microLED display in a limited edition. It is Garmin's top model and designed to be the only gadget needed to explore almost anywhere and track every activity.

This positions it as an very pricey proposition, starting at £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 variant with microLED screen – nearly double the cost of the regular Fenix 8.

You do receive a significant features for your investment, with best-in-class workout, movement and adventure monitoring. The full offline maps of the globe can seamlessly direct you return to the trail if you lose your way absent a phone, and look excellent on the sizable, crisp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of smartwatch battery life even with the screen on all the time, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your mobile carrier, as with other wearables. But unlike competing satellite-enabled devices, SOS messaging is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messages, call functionality and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out jogging, biking or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and texts via satellite are then charged on top, with more expensive plans including different allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have completed setup, you just venture outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned responses you can use to speed things up. Spoken recordings and calls work OK, though as with the majority of wearables, you’re not going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can set it up to on its own send a link to chosen contacts whenever you begin an activity, so they can track your real time location on a map. It’s excellent for following competition progress, but it primarily serves as a utility for someone you trust to be aware of your whereabouts in case something happens. It has generally functioned effectively, though the real position has occasionally lagged when moving in and out of good LTE signal.

These capabilities are accessible 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 guide 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 crucial lifeline, though it is essential to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with options available via the customer service site. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides disposal schemes on new 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).

Conclusion

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re without coverage.

Outcome is an increasingly remarkable outdoor tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin does so without requiring anything else.

This is quite liberating to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the service. At least 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 hates being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors everything with best-in-class GPS, built-in flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and satellite functions require ongoing subscription, limited Garmin Pay financial support, voice capabilities are sluggish, limited smartwatch features versus competing watches.
