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

This latest version of the top-tier Fenix adventure timepiece introduces a life-saving feature: phone-free communication and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by adding cutting-edge cellular tech, along with an optional advanced microLED screen in a limited edition. It is the brand's top device and engineered to be the only gadget required to venture virtually any location and track every activity.

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

You do receive a significant features for your money, with best-in-class workout, activity and adventure monitoring. The full offline maps of the globe can seamlessly direct you return to the path if you get lost absent a phone, and look excellent on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and orbital subscription service instead of depending on a watch plan linked to your phone carrier, like other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack location sharing – so your friends or loved ones can monitor you while engaged in running, biking or comparable activities – along with SOS orbital SOS messaging.

Check-ins and messages over satellite are then charged on top, with more expensive plans offering different allowances of satellite use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the functionality.

Once you have got it set up, you just venture the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable activities, but you are able to place and receive calls, dispatch texts and overall stay connected with your family and friends.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using text or spoken messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can send to expedite communication. Spoken messages and calls work acceptably, although as with most smartwatches, you’re unlikely going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest function. You can set it up to automatically transmit a URL to selected contacts whenever you start an exercise, so they can track your live position on a map. It’s great for following race performance, but it primarily serves as a utility for someone you trust to be aware of your location in case something happens. It has typically functioned well, though the real location has occasionally been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency 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 surprisingly easy to use and could be a crucial lifeline, though it is essential to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options offered via the customer service site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal schemes 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 service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of coverage.

Outcome 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 running out at night or in the remote areas, the Garmin does so without needing anything else.

It is quite liberating to be outside without a phone, but that capability carries quite a cost, both in terms of the substantial price of the watch and the recurring fee of the inReach service to provide the features. At least it is not reliant on your phone provider so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, biking or trekking, but nevertheless desires to be trackable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, super-bright OLED screen, tracks everything with premier GPS, integrated torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital functions need monthly payment, limited Garmin Pay financial compatibility, voice capabilities are sluggish, basic wearable functionality versus Apple/Google/Samsung watches.
