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

This latest iteration of the flagship Fenix outdoor watch includes a potentially lifesaving capability: no-phone messaging and emergency alerts via 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding cutting-edge cellular technology, plus an optional state-of-the-art microLED display in a special edition. This is Garmin's top device and designed to be the only tool needed to venture almost any location and monitor all your movements.

That positions it as an very pricey proposition, starting at £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 variant with microLED screen – nearly double the price of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class fitness, activity and adventure monitoring. Its complete offline mapping of the globe can seamlessly guide you return to the path if you get lost absent a phone, and look excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm size found in other models, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed does have an extra day of smartwatch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calls and Real-Time Location

The company operates its proprietary inReach LTE (4G) and satellite service service instead of depending on a watch plan tied to your mobile carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-capable devices, SOS messaging is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or comparable pursuits – plus SOS satellite SOS alerts.

Check-ins and messages over satellite are then charged on top, with higher-tier plans including different allowances of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After 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 streaming music or comparable tasks, but you can place and receive calls, send texts and overall stay connected with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or voice messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Messaging on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It includes a set of personalizable canned responses you can use to speed things up. Voice recordings and calls work acceptably, although as with most wearables, you’re unlikely going to wish to use it for extended discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a link to selected contacts whenever you start an activity, so they can track your live position on a map. It’s excellent for monitoring competition performance, but it mostly acts as a utility for someone you rely on to be aware of your location in case something happens. It has generally worked effectively, though the real position has occasionally lagged when transitioning in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays 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 surprisingly straightforward to use and could be a crucial safety feature, however it is essential to remember that orbital service is limited to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available via the support site. The battery is certified to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides disposal programs on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans cost 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 adds LTE for messaging, calls and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re without signal.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite freeing to be outdoors without a phone, but that capability comes at quite a price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the features. Fortunately it isn’t dependent on your phone provider so works with any brand of smartphone and carrier.

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

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: very costly, LTE and orbital features need ongoing subscription, limited Garmin Pay financial compatibility, speech features are slow, basic wearable features compared with competing watches.
