Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

This latest version of Garmin's premium Fenix outdoor watch brings a potentially lifesaving feature: phone-free communication and emergency alerts via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding new cellular tech, plus an available advanced microLED screen in a special edition. This is the brand's top model and engineered to be the single tool needed to explore almost any location and monitor every activity.

This positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the regular Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class fitness, movement and adventure tracking. The full offline mapping of the globe can seamlessly direct you back to the path if you lose your way without a phone, and look great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the display always active, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your mobile carrier, like other wearables. However in contrast to competing satellite-enabled devices, emergency communication is not provided for no cost.

Instead, subscriptions start at £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack location tracking – so your friends or family can keep an eye on you while out running, biking or similar pursuits – along with SOS orbital SOS alerts.

Check-ins and texts over orbital are then charged on top, with higher-tier subscriptions including various allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply venture outside without your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, dispatch texts and generally stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally using typed or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a phone number is sufficient to register for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a set of customisable pre-set replies you can send to expedite communication. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically worked effectively, although the actual position has sometimes lagged when moving in and out of good LTE signal.

These features are accessible 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 SOS SOS.

A guide shows 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 straightforward to use and could be a vital lifeline, though it is important to remember that orbital service is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available through the customer service site. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused materials. Garmin provides recycling schemes on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is very freeing to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it is not dependent on your phone provider so works with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, super-bright OLED display, monitors everything with premier GPS, built-in torch, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, basic smartwatch functionality compared with Apple/Google/Samsung watches.
