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

This newest model of the flagship Fenix adventure timepiece includes a potentially lifesaving capability: no-phone messaging and emergency messaging using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available state-of-the-art microLED display in a special edition. This is the brand's premier model and designed to be the single tool needed to explore virtually any location and track every activity.

This positions it as an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the regular Fenix 8.

You do get a lot of features for your investment, with industry-leading workout, activity and adventure tracking. The complete offline maps 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 high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan tied to your mobile provider, like other wearables. But in contrast to competing satellite-capable products, emergency messaging is not included for no cost.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while out jogging, cycling or comparable activities – along with emergency satellite SOS alerts.

Check-ins and texts over satellite are then charged additionally, with more expensive subscriptions including different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, send texts and generally keep in touch with your relatives and friends.

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

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set replies you can use to expedite communication. Voice messages and calls work OK, though as with most wearables, you’re not going to wish to use it for extended conversations as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to automatically send a URL to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned well, although the real position has occasionally lagged when transitioning in and out of strong LTE signal.

All of these features are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is important to remember that satellite coverage is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available through the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled materials. 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 optional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital communication, location update and emergency SOS for when you’re out of coverage.

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

It is quite liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the service. Fortunately it is not dependent on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but still wants to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED display, tracks all activities with premier GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very costly, LTE and orbital functions require monthly payment, restricted Garmin Pay financial support, speech capabilities are slow, limited wearable features compared with Apple/Google/Samsung watches.
