The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This most recent version of Garmin's premium Fenix adventure timepiece introduces a life-saving capability: no-phone communication and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding new mobile technology, plus an available advanced microLED screen in a special edition. It is the brand's top device and designed to be the single tool required to venture almost any location and monitor all your movements.

That makes it an very expensive option, 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 – nearly twice the price of the regular Fenix 8.

You do get a lot of functionality for your money, with best-in-class fitness, movement and adventure monitoring. The full offline mapping of the globe can automatically guide you return to the path if you lose your way absent a phone, and look excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life despite the display always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan tied to your mobile provider, as with other smartwatches. However unlike competing satellite-capable devices, emergency messaging is not included for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and voice messages, calls and LiveTrack position tracking – so your friends or family can monitor you while engaged in jogging, biking or similar pursuits – along with SOS orbital SOS messaging.

Location updates and texts via orbital are then charged additionally, with higher-tier subscriptions offering various allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you just head out outside without your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you can make and take calls, send texts and overall stay connected with your relatives and friends.

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

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable canned responses you can send to speed things up. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a URL to selected contacts every time you start an activity, so they can track your live location on a map. It’s great for following race progress, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has typically worked well, although 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 find the line of sight 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 crucial safety feature, however it is important to remember that satellite service is restricted to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with options offered through the customer service portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled components. Garmin offers recycling 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 service 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 standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re without coverage.

Outcome is an even more impressive outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the service. Fortunately it isn’t reliant on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, biking or hiking, but still wants to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED display, tracks everything with best-in-class GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: extremely costly, LTE and satellite functions need ongoing subscription, restricted Garmin Pay bank compatibility, speech features are slow, basic smartwatch features compared with Apple/Google/Samsung watches.
