Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for Phone-Free Messaging

This most recent model of the flagship Fenix outdoor watch includes a potentially lifesaving feature: no-phone messaging and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new cellular technology, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's top model and designed to be the single gadget required to venture almost anywhere and track every activity.

That positions it as an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the price of the regular Fenix 8.

Users get a significant functionality for your money, with best-in-class fitness, activity and adventure tracking. Its full offline mapping of the world can automatically direct you return to the trail if you lose your way without a phone, and look excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life even with the display on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your mobile provider, as with other smartwatches. However in contrast to competing satellite-enabled products, SOS communication is not included for free.

Rather, plans start at £7.99 or equivalent a month, which provides unlimited LTE text and voice messages, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, cycling or similar pursuits – plus emergency satellite SOS alerts.

Check-ins and messages over orbital are then billed additionally, with more expensive subscriptions offering various allowances of satellite use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have completed setup, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally using typed or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable pre-set replies you can send to expedite communication. Voice messages and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can configure to on its own send a URL to chosen contacts every time you begin an activity, so they can follow your live location on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you trust to know your whereabouts in case something happens. It has typically worked well, although the real position has sometimes lagged when moving in and out of good LTE signal.

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

A on-screen assistance shows you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, however it is important to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with services available through the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal schemes on new purchases.

Price

The Fenix 8 Pro is priced 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).

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re without signal.

Outcome is an even more impressive adventure device for those that want to be unplugged. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to enable the service. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED screen, tracks 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, buttons and touch.

Cons: very costly, LTE and satellite functions need monthly subscription, restricted Garmin Pay financial support, speech features are sluggish, limited wearable features versus Apple/Google/Samsung watches.
