The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Messaging

The latest model of the flagship Fenix outdoor timepiece introduces a potentially lifesaving capability: no-phone messaging and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge mobile technology, plus an optional state-of-the-art microLED screen in a special edition. It is Garmin's top model and engineered to be the single gadget needed to venture almost anywhere and track every activity.

That positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the cost of the standard Fenix 8.

You do receive a lot of features for your investment, with best-in-class workout, movement and adventure monitoring. Its full offline maps of the world can automatically direct you back to the trail if you get lost without a phone, and appear great on the large, crisp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life despite the screen on all the time, enduring a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan tied to your phone carrier, like other smartwatches. However in contrast to competing satellite-capable products, SOS messaging is not included for free.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – along with emergency satellite SOS alerts.

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

Once you have completed setup, you just head out outside minus your phone and the watch will connect to LTE. You can not use it for playing music or similar activities, but you are able to place and receive calls, dispatch texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth via typed or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable canned replies you can use to expedite communication. Voice messages and calls work OK, although as with the majority of wearables, you’re not going to want to use it for extended conversations as the quality is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own transmit a URL to chosen contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically worked effectively, though the actual position has sometimes lagged when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and emergency 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 unexpectedly easy to use and could be a vital lifeline, though it is important to remember that orbital coverage is limited to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with options offered via the customer service portal. 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 offers recycling programs 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 service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly remarkable outdoor device for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing anything else.

It is quite freeing 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 plan to enable the features. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, biking or hiking, but still wants to be trackable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated torch, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very expensive, LTE and satellite features require monthly subscription, limited Garmin Pay bank compatibility, speech features are slow, basic smartwatch features compared with competing watches.
