The Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Messaging

This most recent iteration of the premium Fenix outdoor watch includes a potentially lifesaving capability: phone-free communication and SOS alerts using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new mobile technology, along with an optional state-of-the-art microLED display in a limited edition. It is Garmin's premier model and engineered to be the only gadget needed to explore virtually anywhere and monitor every activity.

This makes it an extremely expensive option, 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 edition with microLED screen – almost twice the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with industry-leading workout, activity and outdoor tracking. The full offline mapping of the world can automatically guide you return to the trail if you get lost without a phone, and look great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, 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 even with the display on all the time, lasting a reliable eight to nine days between charging.

No-Phone Texting, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite service service instead of depending on a watch plan tied to your mobile carrier, as with other wearables. However unlike competing satellite-enabled products, emergency messaging is not provided for free.

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out jogging, cycling or comparable pursuits – plus SOS orbital SOS alerts.

Check-ins and texts over satellite are then charged on top, with higher-tier subscriptions offering different allowances of satellite usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or spoken communications, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a phone number is enough to sign up for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of personalizable canned responses you can send to speed things up. Spoken recordings and calls work acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can configure to on its own send a link to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s great for monitoring competition progress, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically functioned effectively, though the real location has occasionally lagged when transitioning in and out of strong LTE signal.

All of these features are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, 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 essential to remember that orbital service is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered through the support site. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re without signal.

The result is an increasingly remarkable outdoor device for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is very freeing to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the service. Fortunately it isn’t dependent on your phone provider so functions with all make 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 desires to be trackable and reachable. For other users, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with premier GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and orbital functions need monthly subscription, restricted Garmin Pay bank compatibility, voice features are slow, basic wearable functionality compared with competing watches.
