Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

This latest version of the top-tier Fenix outdoor watch introduces a life-saving feature: phone-free communication and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an available state-of-the-art microLED display in a special edition. It is the brand's top device and designed to be the only gadget needed to venture almost anywhere and track all your movements.

This positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the price of the standard Fenix 8.

You do get a lot of features for your investment, with industry-leading workout, movement and adventure tracking. The full offline maps of the globe can automatically direct you back to the path if you lose your way absent a phone, and look great on the large, sharp and super-bright display.

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

Phone-Free Messaging, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan tied to your phone provider, like other smartwatches. But in contrast to Apple or Google's satellite-enabled products, SOS communication is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can monitor you while engaged in jogging, cycling or similar pursuits – plus emergency orbital SOS messaging.

Location updates and texts over orbital are then charged additionally, with more expensive plans including various quotas of orbital use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you simply venture the door without your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you are able to place and receive calls, send texts and generally stay connected with your family and companions.

When you message someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or spoken messages, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a phone number is enough to register for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a set of customisable canned responses you can use to expedite communication. Voice recordings and calls perform acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a link to chosen contacts whenever you start an exercise, so they can track your real time position on a map. It’s excellent for monitoring race progress, but it primarily acts as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has generally worked effectively, though the real position has occasionally lagged when moving in and out of strong LTE coverage.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide shows you how to locate 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 vital safety feature, however it is important to note that satellite service is limited to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

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

Cost

This Fenix 8 Pro is priced 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).

Verdict

This 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 satellite messaging, check-in and emergency SOS for when you’re without coverage.

Outcome is an increasingly impressive adventure device for those that desire to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the remote areas, the Garmin does so without needing anything else.

It is very liberating to be outside without a phone, but that functionality comes at a significant price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the features. At least it is not reliant on your phone carrier so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but still desires to be trackable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED display, monitors all activities with premier GPS, built-in torch, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features require monthly subscription, restricted Garmin Pay financial compatibility, speech features are slow, basic smartwatch features versus competing watches.
