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

The latest model of Garmin's premium Fenix adventure watch introduces a potentially lifesaving capability: no-phone communication and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge mobile tech, along with an available advanced microLED display in a special edition. This is the brand's premier device and engineered to be the only tool needed to venture almost any location and track all your movements.

This makes it an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the regular Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading fitness, movement and outdoor monitoring. Its complete offline maps of the world can seamlessly direct you return to the path if you get lost absent a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life despite the display always active, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan tied to your mobile provider, like other smartwatches. But unlike competing satellite-enabled devices, SOS communication is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack position tracking – so your friends or family can monitor you while out jogging, biking or comparable activities – along with SOS satellite SOS messaging.

Check-ins and texts over orbital are then billed on top, with more expensive subscriptions offering various allowances of satellite use, climbing 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 got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you are able to make and take calls, dispatch texts and generally stay connected with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly 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 recipient is not required to have a Garmin profile to use the Messenger application, just a phone number is enough to sign up for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It has a collection of customisable pre-set responses you can use to expedite communication. Spoken messages and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a link to selected contacts whenever you start an activity, so they can follow your live location on a map. It’s great for monitoring competition progress, but it primarily acts as a tool for someone you trust to know your location in case something happens. It has generally functioned effectively, though the actual position has occasionally lagged when transitioning in and out of strong LTE signal.

These features are available on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location check-ins and SOS 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 crucial lifeline, however it is important to remember that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available through the support 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 components. Garmin offers recycling 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 optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable outdoor tool for those that desire to be phone-free. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outside without a phone, but that capability comes at a significant price, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to provide the service. At least it isn’t dependent on your phone provider so functions with all make of smartphone and carrier.

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

Advantages: LTE and satellite communication, super-bright OLED screen, monitors everything with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very expensive, LTE and orbital features need ongoing subscription, restricted Garmin Pay bank compatibility, speech features are sluggish, basic smartwatch features versus competing watches.
