Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

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

This Fenix 8 Pro builds upon the already impressive Fenix 8 by adding new mobile technology, along with an available state-of-the-art microLED display in a special edition. This is the brand's top model and engineered to be the single tool required to venture almost any location and track every activity.

That makes it an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the standard Fenix 8.

Users get a significant features for your investment, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the world can seamlessly guide you back to the trail if you lose your way without a phone, and look great on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan linked to your phone carrier, like other smartwatches. But unlike competing satellite-enabled devices, SOS messaging is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messages, calls and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out jogging, cycling or similar activities – plus SOS satellite SOS messaging.

Location updates and texts via orbital are then charged on top, with higher-tier subscriptions including different allowances of orbital usage, increasing to a £50 a month all-inclusive 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 minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you are able to make and take calls, dispatch texts and overall keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or spoken messages, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a phone number is enough to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is slow. It has a set of customisable canned replies you can send to speed things up. Spoken messages and calls perform acceptably, though as with most wearables, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically transmit a URL to selected contacts every time you begin 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 know your whereabouts in case an incident occurs. It has generally functioned effectively, although the actual location has sometimes lagged when moving in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is essential to remember that orbital coverage is limited to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with options offered through the support portal. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled components. Garmin offers recycling schemes on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor tool for those that want to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without needing anything else.

This is very liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the colossal price of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it is not dependent on your phone carrier so works with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but still desires to be trackable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED display, monitors all activities with best-in-class GPS, built-in torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: extremely costly, LTE and satellite functions require monthly payment, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable functionality versus competing watches.
