Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for Phone-Free Messaging

The newest iteration of the premium Fenix adventure timepiece introduces a life-saving capability: phone-free communication and SOS messaging via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating new cellular technology, along with an available advanced microLED screen in a limited edition. This is Garmin's top model and designed to be the only tool needed to explore virtually anywhere and track all your movements.

This makes it an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the cost of the regular Fenix 8.

Users get a lot of features for your money, with industry-leading workout, movement and outdoor tracking. The complete offline mapping of the world can automatically guide you back to the path if you get lost without a phone, and look great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra day of watch battery life even with the display on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription service instead of relying on a watch plan tied to your mobile carrier, as with other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not provided for free.

Instead, plans start at £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, cycling or similar activities – along with SOS orbital SOS alerts.

Location updates and messages over orbital are then charged on top, with more expensive plans including various quotas of satellite use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you simply head out the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, send texts and overall stay connected with your relatives and friends.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally via text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It has a collection of customisable canned replies you can send to speed things up. Voice recordings and calls work OK, although as with most smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a URL to selected contacts whenever you begin an exercise, so they can follow your live position on a map. It’s great for following race performance, but it mostly acts as a utility for someone you trust to know your location in case an incident occurs. It has typically worked well, though the actual location has occasionally been delayed when transitioning in and out of good LTE coverage.

These capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance 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 unexpectedly straightforward to use and could be a crucial lifeline, though it is essential to note that orbital service is limited to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with services available via the support site. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused components. Garmin provides recycling programs on new purchases.

Price

The 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 builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re without signal.

The result is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone monitor you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is quite freeing to be outside without a phone, but that functionality carries a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to provide the features. At least it isn’t dependent on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, biking or trekking, but still desires to be trackable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED display, monitors everything with best-in-class GPS, integrated flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and orbital functions need monthly subscription, limited Garmin Pay financial compatibility, voice features are sluggish, basic wearable features compared with Apple/Google/Samsung watches.
