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

This newest iteration of the premium Fenix outdoor timepiece includes a potentially lifesaving feature: no-phone communication and emergency messaging via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular technology, along with an available state-of-the-art microLED display in a special edition. It is the brand's premier model and designed to be the only tool needed to explore almost any location and track every activity.

This positions it as an extremely pricey option, 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 – almost double the cost of the standard Fenix 8.

You do get a lot of features for your investment, with industry-leading fitness, movement and adventure tracking. The full offline mapping of the globe can automatically direct you back to the path if you get lost without a phone, and look excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan tied to your mobile carrier, like other wearables. However in contrast to competing satellite-enabled products, SOS messaging is not included for no cost.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out jogging, biking or comparable pursuits – along with emergency satellite SOS alerts.

Check-ins and messages over satellite are then billed on top, with more expensive subscriptions offering different quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or voice messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, just a phone number is enough to sign up for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned responses you can use to speed things up. Voice recordings and calls work OK, though as with most wearables, you’re not going to wish to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the most useful feature. You can set it up to automatically send a link to chosen contacts every time you start an activity, so they can follow your real time location on a map. It’s excellent for monitoring competition progress, but it primarily acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned well, although the real position has occasionally lagged when moving in and out of strong LTE signal.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide shows you how to locate the clear view to the orbital system, 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 essential to note that orbital coverage is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with options offered via the customer service site. The battery is rated to retain at least 90% of its initial power 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 service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable outdoor device for those that want to be unplugged. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is very liberating to be outside without a phone, but that functionality comes at a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to provide the features. Fortunately it isn’t reliant on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be trackable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, super-bright OLED display, tracks all activities with premier GPS, built-in flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: very expensive, LTE and satellite features need ongoing subscription, limited Garmin Pay financial support, voice features are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
