The Fenix 8 Pro Review: Integrated LTE and Orbital Communication for Phone-Free Texting

This most recent iteration of the premium Fenix adventure watch introduces a potentially lifesaving feature: phone-free communication and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge mobile tech, along with an optional state-of-the-art microLED display in a limited edition. It is the brand's premier model and engineered to be the only gadget required to venture virtually anywhere and monitor all your movements.

That positions it as an extremely pricey 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 double the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with industry-leading fitness, activity and adventure monitoring. The complete offline maps of the globe can seamlessly guide you back to the path if you get lost absent a phone, and look excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life despite the screen on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service service rather than depending on a watch plan linked to your phone provider, as with other wearables. However unlike competing satellite-capable products, SOS communication is not included for no cost.

Instead, subscriptions start at £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, cycling or similar activities – plus emergency orbital SOS messaging.

Check-ins and texts over orbital are then billed on top, with more expensive plans including various quotas of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, dispatch texts and generally keep in touch with your family and companions.

When you text someone, Garmin sends them an SMS from a random 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 spoken messages, 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 works adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set responses you can send to expedite communication. Spoken messages and calls perform acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to on its own send a URL to selected contacts every time you start an exercise, so they can track your real time position on a map. It’s great for following competition performance, but it primarily acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally functioned effectively, though the actual position has sometimes lagged when transitioning in and out of strong LTE coverage.

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

A guide displays you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is important to note that orbital service is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with services offered via the customer service site. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin provides disposal schemes on recent purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on 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 out of coverage.

Outcome is an even more remarkable outdoor tool 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 remote areas, the Garmin accomplishes this without needing additional gear.

This is quite liberating to be outdoors without a phone, but that capability 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 service. Fortunately it isn’t reliant on your phone carrier so works with any make of smartphone and network.

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

Advantages: LTE and satellite messaging, super-bright OLED display, tracks everything with best-in-class GPS, integrated flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and orbital features require monthly payment, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable functionality versus competing watches.
