Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for Phone-Free Messaging

The latest version of Garmin's top-tier Fenix adventure timepiece includes a life-saving feature: phone-free communication and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by adding new cellular technology, plus an available state-of-the-art microLED display in a limited edition. This is the brand's top model and designed to be the only gadget needed to explore virtually any location and monitor 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 model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the price of the standard Fenix 8.

You do get a significant features for your investment, with industry-leading workout, movement and adventure monitoring. The full offline mapping of the world can seamlessly direct you back 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 exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life even with the screen always active, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

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

Rather, plans start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your friends or family can keep an eye on you while out running, biking or similar activities – along with emergency satellite SOS messaging.

Check-ins and texts over orbital are then charged additionally, with more expensive subscriptions including different allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you simply head out 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 make and take calls, dispatch texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via text or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a phone number is sufficient to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of customisable pre-set replies you can send to speed things up. Voice recordings and calls work OK, although as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the quality is not ideal.

LiveTrack is the handiest function. You can set it up to automatically transmit a link to selected contacts every time you begin an exercise, so they can track your real time position on a map. It’s great for monitoring competition performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has generally worked effectively, although the actual location has sometimes lagged when transitioning in and out of strong LTE coverage.

All of these features are available on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A guide displays you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is essential to remember that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with options available through the support site. 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 components. Garmin provides disposal schemes on recent purchases.

Price

This Fenix 8 Pro costs 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).

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re out of signal.

The result is an increasingly impressive adventure tool for those that want to be phone-free. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without needing anything else.

This is quite freeing to be outdoors without a phone, but that capability carries a significant price, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to provide the service. At least it is not dependent on your phone carrier so works with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, biking or trekking, but still desires to be locatable and contactable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated torch, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: very costly, LTE and satellite functions need monthly payment, restricted Garmin Pay bank compatibility, voice capabilities are slow, basic smartwatch functionality versus Apple/Google/Samsung watches.
