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

This newest model of Garmin's premium Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and emergency messaging via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge cellular technology, plus an available state-of-the-art microLED screen in a limited edition. It is the brand's top model and designed to be the only gadget required to venture virtually any location and monitor every activity.

This makes it an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the price of the standard Fenix 8.

Users get a lot of functionality for your money, with industry-leading fitness, movement and outdoor tracking. Its complete offline mapping of the globe can seamlessly guide you back to the path if you get lost without a phone, and look great on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested does have an extra day of smartwatch battery life even with the display always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite service service instead of depending on a watch plan linked to your phone carrier, as with other smartwatches. But unlike Apple or Google's satellite-capable devices, SOS messaging is not provided for no cost.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE text and audio messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or comparable activities – plus emergency orbital SOS alerts.

Check-ins and messages via satellite are then charged additionally, with higher-tier plans including various quotas of orbital use, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the service.

Once you have completed setup, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you can place and receive calls, send texts and generally keep in touch with your family and companions.

Whenever 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 message back and forth using typed or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a phone number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can send to speed things up. Voice recordings and calls perform OK, though as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to selected contacts whenever you start an exercise, so they can follow your live location on a map. It’s great for monitoring competition progress, but it mostly serves as a utility for someone you trust to know your location in case something happens. It has typically worked well, although the real location has sometimes lagged when transitioning in and out of strong LTE coverage.

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

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets communications 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 orbital coverage is restricted to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services available via the support site. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling programs on new purchases.

Price

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans 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 communication, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly impressive outdoor tool for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

This is very liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to enable the features. Fortunately it isn’t reliant on your phone provider so functions with all make of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but still wants to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital functions need monthly payment, restricted Garmin Pay financial compatibility, speech features are sluggish, basic smartwatch functionality versus competing watches.
