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

This latest version of the flagship Fenix adventure watch brings a life-saving capability: phone-free communication and emergency messaging using 4G LTE or orbital links.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge mobile tech, along with an optional advanced microLED display in a special edition. It is the brand's premier device and engineered to be the only tool required to explore almost anywhere and monitor all your movements.

That positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the cost of the standard Fenix 8.

Users receive a significant functionality for your money, with industry-leading workout, movement and outdoor monitoring. Its full offline mapping of the globe can automatically direct you return to the path if you lose your way absent a phone, and appear great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your mobile carrier, as with other wearables. But unlike Apple or Google's satellite-capable devices, emergency communication is not included for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while out jogging, biking or comparable activities – along with emergency orbital SOS messaging.

Check-ins and messages via orbital are then billed on top, with more expensive subscriptions offering various quotas of orbital use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you simply venture outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you are able to make and take calls, dispatch texts and overall keep in touch with your family and companions.

When you text someone, Garmin dispatches them an SMS from a random phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set responses you can send to speed things up. Voice recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to wish to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to selected contacts every time you start an exercise, so they can track your live location on a map. It’s great for following race progress, but it primarily acts as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally functioned effectively, although the actual position has occasionally been delayed when transitioning in and out of good LTE coverage.

All of these features are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide shows you how to find the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is essential to remember that satellite service is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with services available via the support portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal programs on recent 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 subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re out of signal.

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

This is very freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the service. Fortunately it isn’t dependent on your phone provider so works with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or hiking, but still desires to be trackable and reachable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED display, monitors all activities with premier GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and orbital functions need monthly subscription, restricted Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
