Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity 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 messaging using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile tech, along with an optional advanced microLED display in a limited edition. This is Garmin's top device and engineered to be the only tool needed to explore almost any location and monitor every activity.

That makes it an extremely pricey proposition, priced from £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 edition with microLED screen – nearly twice the price of the regular Fenix 8.

You do receive a lot of functionality for your money, with industry-leading workout, activity and adventure tracking. The full offline maps of the world can seamlessly guide you return to the trail if you lose your way absent a phone, and appear excellent on the large, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size found in other models, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed does have an additional day of smartwatch battery life despite the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your phone provider, as with other wearables. But unlike competing satellite-enabled products, emergency messaging is not included for no cost.

Instead, plans start at £7.99 or similar a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack position tracking – so your friends or family can keep an eye on you while engaged in jogging, cycling or similar pursuits – along with SOS satellite SOS messaging.

Check-ins and texts via satellite are then billed on top, with higher-tier plans offering various quotas of satellite usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the service.

After you have got it set up, you just venture outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable activities, but you are able to place and receive calls, send texts and generally stay connected with your family and companions.

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using typed or spoken messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can send to expedite communication. Spoken recordings and calls work OK, although as with most wearables, you’re not going to wish to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to chosen contacts every time you start an activity, so they can track your real time location on a map. It’s excellent for monitoring competition performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has typically worked effectively, although the real position has sometimes lagged when transitioning in and out of good LTE coverage.

These features 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 check-ins and SOS SOS.

A on-screen assistance displays 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 straightforward to use and could be a vital lifeline, though it is important to note that satellite coverage is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with options offered through the support portal. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin provides disposal programs on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

The result is an even more remarkable outdoor device for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is quite liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to provide the features. At least it is not reliant on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or trekking, but still desires to be trackable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, built-in torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Drawbacks: very costly, LTE and satellite features require ongoing payment, limited Garmin Pay bank compatibility, voice features are sluggish, limited wearable functionality compared with competing watches.
