Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Messaging

The most recent iteration of Garmin's top-tier Fenix outdoor watch includes a potentially lifesaving capability: no-phone messaging and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating cutting-edge mobile technology, along with an available state-of-the-art microLED display in a limited edition. It is the brand's premier model and engineered to be the only tool needed to explore virtually any location and monitor all your movements.

That makes it an very pricey proposition, 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 edition with microLED screen – nearly double the cost of the standard Fenix 8.

Users get a significant features for your investment, with best-in-class workout, activity and adventure monitoring. The full offline maps of the globe can automatically direct you return to the trail if you lose your way without a phone, and appear great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the screen always active, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service service 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 communication is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack position tracking – so your friends or family can monitor you while engaged in running, cycling or similar activities – along with emergency orbital SOS messaging.

Location updates and texts over orbital are then charged additionally, with more expensive subscriptions including various quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period 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 link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and generally stay connected with your family and friends.

When you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or spoken communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable pre-set replies you can use to speed things up. Spoken messages and calls perform acceptably, although as with most wearables, you’re not going to want to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically send a link to chosen contacts every time you begin an activity, so they can follow your live position on a map. It’s excellent for following competition progress, but it primarily acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned well, though the real position has occasionally been delayed when transitioning in and out of good LTE coverage.

These capabilities are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance shows you how to find the clear view 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 safety feature, however it is important to remember that orbital service is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services offered through the customer service portal. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal schemes on new purchases.

Cost

The Fenix 8 Pro is priced 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

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re out of coverage.

The result is an increasingly remarkable adventure device for those that want to be phone-free. If you want to have someone monitor you from afar while running out at night or in the remote areas, the Garmin does so without needing additional gear.

This is quite freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to enable the service. At least it isn’t reliant on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, cycling or trekking, but still desires to be trackable and reachable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, high-luminance OLED display, monitors everything with premier GPS, built-in torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: extremely costly, LTE and satellite features require ongoing subscription, limited Garmin Pay financial support, voice capabilities are slow, limited smartwatch functionality versus competing watches.
