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

The latest model of the flagship Fenix adventure timepiece brings a life-saving feature: phone-free communication and emergency messaging using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular technology, plus an available state-of-the-art microLED display in a limited edition. It is Garmin's top model and engineered to be the single gadget needed to venture almost any location and track all your movements.

That positions it as an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the cost of the standard Fenix 8.

Users receive a significant functionality for your investment, with industry-leading workout, movement and adventure monitoring. The full offline mapping of the globe can automatically direct you return to the trail if you lose your way without a phone, and look excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription plan instead of depending on a watch plan linked to your phone carrier, like other wearables. But unlike Apple or Google's satellite-enabled devices, SOS messaging is not included for free.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE SMS and audio messaging, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while out running, biking or comparable pursuits – along with emergency orbital SOS alerts.

Location updates and texts over satellite are then charged additionally, with more expensive plans offering different quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the service.

Once you have completed setup, you simply venture the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to expedite communication. Voice recordings and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own send a URL to selected contacts every time you begin an activity, so they can track your real time location on a map. It’s excellent for following race progress, but it mostly acts as a utility for someone you rely on to know your location in case an incident occurs. It has typically worked well, though the real position has occasionally lagged when moving in and out of good LTE signal.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is essential to note that satellite service is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available through the support site. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled materials. Garmin offers recycling programs on recent purchases.

Cost

The 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).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

It is very freeing to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to enable the service. At least it is not reliant on your phone provider so works with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, cycling or trekking, but still desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks everything with best-in-class GPS, built-in torch, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and orbital functions need ongoing subscription, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, basic wearable functionality compared with Apple/Google/Samsung watches.
