Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Messaging

The latest model of the flagship Fenix outdoor watch brings a potentially lifesaving feature: no-phone communication and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new cellular tech, along with an optional state-of-the-art microLED display in a special edition. It is the brand's premier model and engineered to be the only tool required to explore almost any location and track all your movements.

This positions it as an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the cost of the standard Fenix 8.

Users receive a lot of functionality for your money, with industry-leading workout, activity and outdoor monitoring. Its full offline maps of the globe can automatically direct you return to the trail if you lose your way without a phone, and appear excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of smartwatch battery life despite the screen on all the time, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your phone carrier, like other smartwatches. But unlike Apple or Google's satellite-enabled products, emergency communication is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and voice messages, call functionality and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in jogging, cycling or similar pursuits – plus emergency satellite SOS alerts.

Check-ins and messages via orbital are then billed on top, with more expensive subscriptions including different quotas of satellite 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 service.

Once you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to make and take calls, dispatch texts and overall stay connected with your relatives and friends.

When you message 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 application, you can then message back and forth using typed or spoken communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It has a set of personalizable canned responses you can send to speed things up. Spoken recordings and calls perform acceptably, though as with the majority of smartwatches, you’re unlikely going to want to use it for extended discussions as the quality is less than ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a link to selected contacts every time you start an exercise, so they can follow your live position on a map. It’s excellent for following competition progress, but it primarily acts as a utility for someone you trust to know your whereabouts in case something happens. It has typically worked well, though the real position has occasionally been delayed when moving in and out of strong LTE coverage.

All of these capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and emergency SOS.

A on-screen assistance displays you how to locate 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 coverage is limited to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with options offered via the customer service site. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal 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 subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor tool for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without needing anything else.

It is quite freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, cycling or trekking, but still wants to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks everything with best-in-class GPS, integrated torch, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Cons: extremely costly, LTE and satellite features require monthly subscription, limited Garmin Pay bank compatibility, voice capabilities are slow, limited wearable functionality versus competing watches.
