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

The newest version of Garmin's top-tier Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new mobile tech, along with an optional state-of-the-art microLED screen in a limited edition. This is the brand's premier device and designed to be the single tool needed to venture almost anywhere and track all your movements.

That positions it as an very 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 edition with microLED display – nearly twice the cost of the standard Fenix 8.

You do receive a lot of features for your money, with best-in-class fitness, activity and outdoor monitoring. Its full offline mapping of the world can automatically direct you return to the trail if you get lost absent a phone, and look great on the large, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an extra day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your phone provider, like other smartwatches. However in contrast to Apple or Google's satellite-capable devices, emergency messaging is not included for no cost.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messages, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in jogging, biking or similar activities – along with SOS orbital SOS alerts.

Check-ins and texts via orbital are then billed on top, with higher-tier subscriptions including various allowances of orbital usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have completed setup, you just venture the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using text or voice messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to speed things up. Voice messages and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the quality is not fantastic.

LiveTrack is the most useful function. You can configure to on its own send a URL to selected contacts whenever you begin an activity, so they can follow your real time location on a map. It’s excellent for monitoring competition progress, but it primarily serves as a utility for someone you rely on to be aware of your location in case something happens. It has generally worked effectively, although the real position has occasionally been delayed when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to note that satellite service is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with options available through the support site. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain 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 additional Garmin inReach subscription plans begin 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 orbital communication, check-in and emergency SOS for when you’re out of signal.

The result is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without needing 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 colossal 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 functions with all make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget 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 money when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED display, monitors all activities with premier GPS, integrated flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: very costly, LTE and satellite functions require monthly payment, limited Garmin Pay financial support, voice features are sluggish, limited wearable functionality compared with Apple/Google/Samsung watches.
