Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for Phone-Free Messaging

This newest model of the premium Fenix outdoor timepiece includes a potentially lifesaving capability: no-phone communication and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular technology, plus an optional state-of-the-art microLED display in a special edition. This is Garmin's top device and designed to be the only tool required to explore virtually anywhere and track all your movements.

This makes it an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the regular Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class workout, movement and outdoor monitoring. Its full offline maps of the globe can seamlessly direct you return to the trail if you lose your way without a phone, and appear excellent on the large, sharp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life even with the display always active, enduring a solid eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription service rather than relying on a watch plan tied to your phone carrier, as with other wearables. But in contrast to competing satellite-capable devices, SOS messaging is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and audio messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while out jogging, cycling or comparable activities – along with emergency satellite SOS messaging.

Location updates and texts over satellite are then billed on top, with higher-tier subscriptions offering different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You can not use it for streaming music or similar tasks, but you can make and take calls, send texts and generally stay connected with your relatives and friends.

Whenever you text someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via text or spoken messages, and initiate 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 functions fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can send to speed things up. Spoken messages and calls perform acceptably, although as with most wearables, you’re unlikely going to wish to use it for extended discussions as the quality is not fantastic.

LiveTrack is the most useful function. You can configure to on its own send a link to selected contacts whenever you begin an exercise, so they can track your real time position on a map. It’s excellent for following competition performance, but it primarily acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked effectively, although the real position has occasionally lagged when moving 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 areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is important to remember that orbital coverage is limited to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with services offered through the customer service site. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin provides recycling programs on recent purchases.

Price

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly impressive adventure device for those that want to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is quite liberating to be outdoors without a phone, but that capability carries a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to enable the service. At least it isn’t reliant on your phone carrier so works with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but still wants to be locatable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors all activities with premier GPS, built-in flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: extremely expensive, LTE and orbital features require monthly subscription, restricted Garmin Pay bank support, voice features are sluggish, limited wearable functionality compared with competing watches.
