The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Texting

The newest version of the premium Fenix outdoor watch introduces a potentially lifesaving feature: phone-free messaging and emergency alerts using 4G LTE or satellite connections.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating cutting-edge cellular tech, plus an available state-of-the-art microLED display in a special edition. It is the brand's premier device and engineered to be the single tool needed to explore virtually any location and monitor all your movements.

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

Users get a lot of functionality for your investment, with industry-leading workout, movement and outdoor monitoring. Its complete offline mapping of the globe can automatically direct you return to the path if you get lost without a phone, and look excellent on the large, crisp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm size available in other models, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen always active, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan linked to your mobile carrier, like other wearables. However in contrast to Apple or Google's satellite-enabled products, SOS messaging is not included for free.

Instead, plans start at £7.99 or similar a month, which provides unlimited LTE text and voice messages, call functionality and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, biking or similar activities – along with emergency orbital SOS alerts.

Location updates and texts via satellite are then charged on top, with higher-tier subscriptions offering various allowances of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, 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 arbitrary number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally via typed or voice messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set replies you can send to speed things up. Voice recordings and calls perform acceptably, though as with the majority of wearables, you’re not going to want to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a link to chosen contacts whenever you start an activity, so they can follow your live position on a map. It’s excellent for following race performance, but it primarily acts as a utility for someone you trust to be aware of your location in case an incident occurs. It has typically functioned effectively, though the real position has sometimes been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are available on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, however it is essential to remember that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available via the customer service site. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling programs on recent purchases.

Cost

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

Verdict

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

Outcome is an even more remarkable outdoor device for those that want to be phone-free. If you want to have someone monitor you from afar while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outside without a phone, but that functionality carries a significant cost, both in terms of the colossal price of the watch and the monthly fee of the inReach service to provide the features. At least it isn’t reliant on your phone provider so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, cycling or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and satellite features need ongoing subscription, limited Garmin Pay financial compatibility, voice capabilities are slow, limited smartwatch features compared with competing watches.
