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

This newest model of Garmin's flagship Fenix outdoor watch introduces a potentially lifesaving capability: phone-free communication and emergency alerts via 4G LTE or satellite links.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding new cellular technology, along with an optional state-of-the-art microLED screen in a limited edition. It is Garmin's premier model and engineered to be the only gadget needed to venture almost anywhere and track all your movements.

This 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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the price of the standard Fenix 8.

Users get a significant features for your investment, with industry-leading workout, movement and outdoor monitoring. Its complete offline mapping of the globe can automatically guide you back to the path if you get lost without a phone, and appear great on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed does have an extra day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription service rather than relying on a watch plan linked to your phone carrier, as with other wearables. But in contrast to competing satellite-enabled devices, SOS communication is not included for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can monitor you while out jogging, cycling or similar pursuits – along with emergency orbital SOS alerts.

Location updates and texts over orbital are then billed on top, with higher-tier plans offering various allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, but you can place and receive calls, send texts and generally stay connected with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via typed or spoken messages, 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.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned replies you can use to expedite communication. Spoken recordings and calls perform OK, although as with most wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can configure to automatically send a link to selected contacts every time you begin an exercise, so they can track your live position on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you rely on to know your location in case something happens. It has generally functioned well, though the actual position has sometimes lagged when moving in and out of good LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to remember that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered via the support portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides disposal programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of signal.

Outcome is an even more impressive adventure device for those that desire to be unplugged. If you wish to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is very liberating to be outdoors without a phone, but that capability carries a significant price, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone carrier so functions with all make of smartphone and network.

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

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with premier GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital functions need ongoing subscription, limited Garmin Pay bank support, voice capabilities are sluggish, basic smartwatch functionality compared with Apple/Google/Samsung watches.
