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

This newest model of Garmin's premium Fenix adventure timepiece introduces a life-saving feature: no-phone messaging and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding new mobile tech, plus an optional advanced microLED display in a limited edition. It is Garmin's premier device and engineered to be the only tool needed to venture almost anywhere and track all your movements.

That positions it as an extremely 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 screen – almost double the cost of the regular Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading workout, activity and adventure tracking. The complete offline mapping of the world can automatically guide you return to the trail if you get lost absent a phone, and look great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm version found in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed does have an extra day of smartwatch battery life despite the display always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company operates its own inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your mobile carrier, as with other wearables. However in contrast to competing satellite-capable devices, SOS messaging is not provided for no cost.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while out jogging, cycling or similar activities – plus emergency satellite SOS alerts.

Check-ins and messages over orbital are then charged on top, with more expensive plans offering various quotas of orbital usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the service.

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 playing music or comparable activities, but you can make and take calls, dispatch texts and overall stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally via typed or voice messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It has a collection of personalizable canned responses you can send to expedite communication. Spoken recordings and calls work acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to selected contacts every time you start an exercise, so they can track your real time position on a map. It’s excellent for monitoring race performance, but it mostly acts as a tool for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned well, although the real position has occasionally lagged when moving in and out of strong LTE coverage.

These capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, though it is important to remember that orbital coverage is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with services offered through the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin offers disposal schemes 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 plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re without signal.

The result is an even more remarkable adventure device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is very freeing to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to provide the features. At least it isn’t reliant on your phone carrier so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless wants to be locatable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and satellite functions require ongoing subscription, restricted Garmin Pay financial support, speech capabilities are slow, basic wearable functionality compared with competing watches.
