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

The most recent iteration of the premium Fenix adventure timepiece includes a life-saving feature: no-phone messaging and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating new mobile tech, plus an available state-of-the-art microLED display in a limited edition. It is the brand's premier device and engineered to be the only gadget required to venture virtually any location and track every activity.

This positions it as an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the cost of the regular Fenix 8.

You do get a significant features for your money, with industry-leading workout, activity and outdoor monitoring. Its complete offline mapping of the globe can seamlessly direct you back to the trail if you get lost absent a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed does have an extra day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your phone carrier, as with other wearables. However unlike competing satellite-enabled products, SOS communication is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while out jogging, cycling or comparable activities – along with SOS orbital SOS alerts.

Location updates and messages via satellite are then billed additionally, with higher-tier subscriptions offering different allowances of satellite usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can place and receive calls, send texts and overall stay connected with your family and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via text or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can use to speed things up. Voice messages and calls work OK, although as with the majority of wearables, you’re not going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can set it up to on its own send a link to selected contacts whenever you begin an exercise, so they can track your live position on a map. It’s great for monitoring competition progress, but it mostly serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked well, although the real location has occasionally been delayed when transitioning in and out of good 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 kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is important to remember that satellite coverage is limited to the US mainland, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available via the customer service portal. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal schemes on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor tool for those that desire to be unplugged. If you want to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin does so without needing additional gear.

It is quite freeing to be outdoors without a phone, but that capability carries quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to enable the service. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

This 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 reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite messaging, high-luminance OLED display, monitors everything with best-in-class GPS, integrated torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and orbital features need monthly payment, restricted Garmin Pay financial support, speech capabilities are sluggish, basic wearable features versus Apple/Google/Samsung watches.
