Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for Phone-Free Messaging

The most recent iteration of the premium Fenix adventure watch brings a life-saving capability: phone-free messaging and emergency messaging via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile tech, plus an optional advanced microLED screen in a special edition. This is the brand's premier model and engineered to be the single gadget required to explore almost any location and monitor every activity.

That makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

Users get a lot of features for your investment, with industry-leading workout, movement and adventure monitoring. The complete offline mapping of the globe can automatically guide you return to the path if you get lost absent a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the display always active, enduring a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and orbital service service instead of depending on a watch plan tied to your phone provider, as with other wearables. However in contrast to competing satellite-capable devices, SOS messaging is not included for no cost.

Rather, plans start at £7.99 or equivalent a month, which provides unlimited LTE text and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can monitor you while out jogging, biking or similar activities – along with SOS orbital SOS alerts.

Location updates and texts via orbital are then billed additionally, with higher-tier plans offering different quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to place and receive calls, send texts and generally stay connected with your relatives and friends.

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

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It has a collection of personalizable canned replies you can send to speed things up. Voice messages and calls work acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to selected contacts every time you begin an exercise, so they can follow your real time position on a map. It’s excellent for following competition performance, but it primarily acts as a utility for someone you trust to know your whereabouts in case something happens. It has typically worked well, though the actual location has occasionally been delayed when moving in and out of good LTE signal.

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

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is important to remember that orbital coverage is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered through the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled components. Garmin provides recycling schemes on new purchases.

Price

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).

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure tool for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is very liberating to be outside without a phone, but that functionality carries quite a cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to enable the features. At least it is not dependent on your phone carrier so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks everything with premier GPS, integrated torch, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very costly, LTE and orbital features need ongoing subscription, limited Garmin Pay bank compatibility, voice capabilities are sluggish, limited wearable features compared with competing watches.
