The Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for Phone-Free Texting

This latest version of Garmin's premium Fenix adventure timepiece brings a life-saving capability: phone-free messaging and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an available advanced microLED display in a special edition. This is the brand's premier model and engineered to be the single gadget needed to explore almost any location and track every activity.

This positions it as an extremely expensive option, priced from £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 edition with microLED screen – nearly double the cost of the standard Fenix 8.

You do receive a significant features for your investment, with best-in-class workout, activity and adventure monitoring. Its full offline mapping of the globe can automatically direct you return to the trail if you lose your way absent a phone, and appear excellent on the large, crisp and super-bright touchscreen.

The 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 bigger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life despite the display always active, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan tied to your phone carrier, like other wearables. However in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – plus SOS satellite SOS messaging.

Check-ins and messages over satellite are then charged additionally, with higher-tier plans including different quotas of orbital use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and companions.

Whenever you text 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 communicate back and forth using typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a mobile number is enough to sign up 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 personalizable pre-set responses you can use to speed things up. Spoken messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to selected contacts whenever you begin an activity, so they can follow your live location on a map. It’s great for monitoring race 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 worked well, though the actual position has sometimes lagged when transitioning in and out of good LTE coverage.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide displays you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, though it is important to remember that orbital service is restricted to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered via the customer service portal. 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 recycling programs on recent purchases.

Cost

This Fenix 8 Pro costs 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 builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of signal.

The result is an even more impressive outdoor device for those that want to be phone-free. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite liberating to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to enable the service. At least it is not dependent on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, tracks everything with best-in-class GPS, integrated torch, 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, buttons and touch.

Cons: extremely costly, LTE and satellite features require monthly subscription, limited Garmin Pay financial compatibility, speech capabilities are slow, limited smartwatch features versus competing watches.
