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

The newest version of the premium Fenix outdoor watch brings a life-saving feature: no-phone communication and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding cutting-edge mobile tech, plus an optional advanced microLED display in a special edition. This is Garmin's premier model and designed to be the only tool required to explore virtually anywhere and track all your movements.

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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the standard Fenix 8.

You do get a significant features for your investment, with best-in-class fitness, activity and outdoor monitoring. The complete offline mapping of the world can automatically guide you return to the trail if you lose your way without a phone, and look excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other models, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of watch battery life despite the display always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your mobile provider, like other smartwatches. However unlike Apple or Google's satellite-capable products, emergency messaging is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messaging, call functionality and LiveTrack position tracking – so your friends or family can monitor you while out jogging, cycling or comparable pursuits – plus SOS satellite SOS messaging.

Check-ins and messages over orbital are then charged additionally, with more expensive subscriptions offering various allowances of orbital use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have completed setup, you simply venture the door 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 family and companions.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via typed or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set replies you can send to expedite communication. Spoken messages and calls perform OK, though as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to automatically send a link to selected 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 mostly acts as a tool for someone you rely on to be aware of your location in case something happens. It has generally functioned effectively, although the actual location has occasionally lagged when moving in and out of good LTE signal.

These features 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 send texts, position 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 easy to use and could be a crucial lifeline, though it is important to remember that satellite service is restricted to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered through the customer service site. The battery is certified to retain at least 90% of its original power after two years of weekly charging. The watch lacks any recycled materials. Garmin offers recycling schemes 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 packages cost 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 messaging, call functionality and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of signal.

The result is an increasingly impressive adventure device for those that want to be unplugged. If you want to have someone monitor you remotely while running out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it isn’t dependent on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but still wants to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors everything with best-in-class GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay bank support, speech features are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
