Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Texting

This most recent model of the flagship Fenix adventure watch introduces a potentially lifesaving capability: phone-free communication and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a limited edition. This is the brand's premier device and engineered to be the single tool required to venture almost anywhere and monitor every activity.

That makes it an extremely expensive proposition, priced from £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 variant with microLED display – nearly double the price of the regular Fenix 8.

Users get a lot of features for your money, with best-in-class fitness, movement and adventure tracking. Its complete offline mapping of the world can automatically guide you return to the path if you lose your way without a phone, and appear excellent on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an additional day of watch battery life even with the screen always active, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calls 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. However unlike Apple or Google's satellite-capable products, SOS communication is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messaging, calls and LiveTrack location sharing – so your friends or loved ones can keep an eye on you while engaged in running, biking or comparable pursuits – plus SOS orbital SOS messaging.

Check-ins and messages via satellite are then charged on top, with higher-tier subscriptions offering different allowances of satellite use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the functionality.

Once you have got it set up, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your family and friends.

Whenever 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 application, you can then message back and forth using typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a mobile number is sufficient to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set responses you can use to expedite communication. Spoken messages and calls perform OK, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to automatically transmit a URL to chosen contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it primarily serves as a utility for someone you rely on to know your whereabouts in case something happens. It has generally worked well, although the real location has occasionally lagged when moving in and out of good LTE coverage.

These capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide shows you how to find the clear view 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 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 excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with services available through the customer service portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin offers disposal programs on recent purchases.

Cost

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

Conclusion

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is very liberating to be outside without a phone, but that functionality comes at a significant price, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the features. At least it is not dependent on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, biking or hiking, but nevertheless wants to be trackable and reachable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and orbital features require monthly subscription, limited Garmin Pay financial support, speech capabilities are slow, basic wearable features compared with competing watches.
