The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

The latest model of the top-tier Fenix adventure timepiece includes a life-saving feature: phone-free messaging and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new cellular technology, plus an available state-of-the-art microLED screen in a limited edition. It is the brand's top model and engineered to be the only gadget required to venture virtually anywhere and track all your movements.

This makes it an very expensive option, starting at £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 display – almost twice the price of the regular Fenix 8.

Users get a lot of functionality for your investment, with best-in-class workout, movement and outdoor monitoring. The complete offline maps of the globe can seamlessly guide you back to the trail if you get lost without a phone, and appear excellent on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the display always active, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan linked to your mobile carrier, as with other wearables. But in contrast to Apple or Google's satellite-enabled devices, emergency messaging is not included for free.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messages, call functionality and LiveTrack position tracking – so your friends or family can monitor you while engaged in jogging, cycling or comparable activities – along with emergency orbital SOS alerts.

Check-ins and texts over satellite are then billed additionally, with more expensive plans offering various quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the functionality.

After you have got it set up, you simply venture outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using typed or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Texting on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can send to expedite communication. Spoken messages and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the quality is not fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a link to selected contacts every time you start an exercise, so they can follow your live position on a map. It’s excellent for monitoring competition performance, but it primarily serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned effectively, although the actual location has sometimes lagged when moving in and out of strong LTE coverage.

These capabilities are available on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is important to remember that satellite service is limited to the US mainland, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services available via the customer service site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin provides recycling schemes on recent purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

It is very liberating to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to enable the features. Fortunately it isn’t dependent on your phone carrier so works with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but still desires to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and satellite features need monthly subscription, limited Garmin Pay financial compatibility, voice capabilities are slow, limited smartwatch features versus competing watches.
