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

The latest version of the premium Fenix adventure watch introduces a potentially lifesaving capability: no-phone communication and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge mobile tech, along with an optional state-of-the-art microLED screen in a special edition. This is Garmin's top device and engineered to be the single gadget needed to explore almost anywhere and monitor all your movements.

That positions it as an very pricey 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.

You do receive a significant features for your investment, with best-in-class fitness, activity and adventure monitoring. The full offline maps of the globe can automatically direct you back to the path if you get lost without a phone, and appear great on the sizable, crisp and super-bright display.

This 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 big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite subscription service instead of relying on a watch plan tied to your mobile carrier, like other smartwatches. However in contrast to competing satellite-capable devices, SOS messaging is not provided for free.

Rather, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and voice messages, call functionality and LiveTrack location sharing – so your friends or family can monitor you while out running, biking or similar pursuits – along with emergency orbital SOS alerts.

Location updates and messages via satellite are then charged on top, with more expensive subscriptions including different quotas of orbital use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can evaluate the functionality.

After you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You can not use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

When you message 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 app, you can then communicate reciprocally via text or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a mobile 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 includes a collection of customisable pre-set replies you can send to expedite communication. Voice messages and calls perform OK, although as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can configure to on its own send a link to chosen contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for following race progress, but it primarily acts as a utility for someone you rely on to know your location in case something happens. It has generally worked effectively, although the real location has occasionally been delayed when moving in and out of good LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide shows you how to find the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is essential to note that satellite service is restricted to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services offered via the customer service site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal programs on new purchases.

Price

The 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 takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re without signal.

Outcome is an even more remarkable outdoor tool for those that desire to be unplugged. If you want to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is quite freeing to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to provide the features. Fortunately it is not dependent on your phone carrier so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but still desires to be locatable and contactable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED display, tracks everything with premier GPS, integrated torch, phone and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite features need monthly subscription, limited Garmin Pay bank support, voice features are slow, limited wearable features versus Apple/Google/Samsung watches.
