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

The most recent version of the premium Fenix adventure timepiece introduces a life-saving capability: phone-free messaging and SOS alerts using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new cellular tech, plus an available state-of-the-art microLED screen in a special edition. It is the brand's top device and engineered to be the only gadget required to explore virtually any location and track every activity.

This positions it as an extremely pricey option, 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 display – nearly twice the cost of the regular Fenix 8.

Users get a significant features for your money, with best-in-class workout, movement and adventure monitoring. Its complete offline maps of the world can automatically direct you return to the path if you lose your way absent a phone, and look excellent on the sizable, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed boasts an additional day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your phone provider, as with other smartwatches. However in contrast to Apple or Google's satellite-enabled devices, SOS communication is not provided for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack location sharing – so your friends or family can keep an eye on you while out running, cycling or similar pursuits – along with SOS satellite SOS messaging.

Location updates and messages over satellite are then charged on top, with more expensive plans offering different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the functionality.

After you have got it set up, you simply head out the door minus your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you are able to place and receive calls, send texts and generally keep in touch with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then message reciprocally using typed or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a mobile number is enough to register for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can use to expedite communication. Voice recordings and calls work acceptably, although as with the majority of smartwatches, you’re unlikely going to want to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to chosen contacts every time you begin an activity, so they can track your real time position on a map. It’s great for following race performance, but it mostly serves as a utility for someone you rely on to know your location in case something happens. It has generally functioned well, although the actual location has occasionally been delayed when moving in and out of good LTE coverage.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A guide displays you how to find 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 crucial safety feature, however it is essential to remember that orbital service is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services 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 does not contain any recycled materials. 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 optional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable outdoor tool for those that want to be phone-free. If you wish to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

It is quite liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to provide the features. At least it isn’t reliant on your phone provider so functions with any make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or trekking, but still desires to be locatable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with premier GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and satellite functions need monthly subscription, restricted Garmin Pay bank support, speech features are slow, limited smartwatch features versus competing watches.
