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

The newest version of Garmin's top-tier Fenix outdoor timepiece includes a life-saving capability: phone-free messaging and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new cellular technology, plus an available advanced microLED screen in a limited edition. This is the brand's top model and designed to be the single gadget required to venture almost anywhere and monitor every activity.

This makes it an extremely pricey proposition, starting at £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 variant with microLED display – almost double the cost of the regular Fenix 8.

Users receive a lot of functionality for your money, with industry-leading fitness, movement and adventure monitoring. The complete offline maps of the globe can automatically direct you back to the path if you lose your way absent a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm version found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an additional day of watch battery life despite the display on all the time, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital service plan rather than depending on a watch plan linked to your mobile carrier, as with other smartwatches. But unlike competing satellite-capable devices, SOS messaging is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can monitor you while out jogging, cycling or similar pursuits – plus emergency orbital SOS alerts.

Location updates and texts via satellite are then billed on top, with more expensive subscriptions offering various allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you just venture outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, send texts and generally stay connected with your family and friends.

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

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of personalizable pre-set responses you can use to expedite communication. Voice messages and calls work OK, although as with the majority of wearables, you’re not going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own send a URL to selected contacts whenever you start an exercise, so they can track your real time location on a map. It’s great for following race performance, but it mostly acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned well, though the real position has occasionally lagged when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is important to note that satellite service is limited to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services available via the support site. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers recycling schemes on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re without coverage.

Outcome is an even more remarkable outdoor device for those that desire to be unplugged. 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 additional gear.

It is very liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it is not reliant on your phone carrier so works with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be trackable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED display, monitors everything with premier GPS, integrated flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Cons: extremely costly, LTE and satellite functions require monthly payment, restricted Garmin Pay bank support, speech capabilities are slow, basic wearable features versus Apple/Google/Samsung watches.
