The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

This latest iteration of Garmin's premium Fenix outdoor timepiece brings a life-saving feature: phone-free messaging and SOS alerts via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new cellular technology, plus an optional advanced microLED display in a special edition. It is the brand's premier model and engineered to be the single gadget needed to venture almost anywhere and monitor every activity.

That makes it an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the price of the regular Fenix 8.

You do receive a lot of functionality for your investment, with best-in-class fitness, activity and adventure monitoring. Its complete offline mapping of the world can seamlessly direct you back to the trail if you get lost absent a phone, and appear excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite service service instead of relying on a watch plan linked to your mobile provider, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled products, emergency communication is not included for no cost.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack location sharing – so your friends or family can keep an eye on you while out jogging, biking or similar activities – plus emergency orbital SOS alerts.

Check-ins and messages over orbital are then billed additionally, with higher-tier subscriptions including different allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply head out outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and overall stay connected with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via text or spoken communications, and initiate voice calls. Your contact 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 typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable pre-set responses you can use to speed things up. Voice recordings and calls work OK, although as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the quality is not fantastic.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to chosen contacts every time you start an exercise, so they can track your live position on a map. It’s great for monitoring race performance, but it mostly serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned effectively, though the actual location has occasionally lagged when moving in and out of strong LTE signal.

These capabilities are accessible on other Garmin watches 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, position check-ins and SOS SOS.

A guide shows 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 unexpectedly straightforward to use and could be a crucial lifeline, though it is important to remember that orbital coverage is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered through the support portal. The battery is certified to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin offers 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 optional Garmin inReach service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of signal.

The result is an even more remarkable adventure tool for those that desire to be unplugged. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is quite freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to provide the features. At least it isn’t dependent on your phone provider so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, biking or hiking, but nevertheless wants to be trackable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors all activities with premier GPS, integrated flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and satellite features need ongoing subscription, restricted Garmin Pay financial support, voice capabilities are slow, limited wearable features compared with competing watches.
