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

The most recent version of Garmin's top-tier Fenix outdoor watch introduces a potentially lifesaving capability: phone-free messaging and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating new mobile tech, along with an available state-of-the-art microLED display in a special edition. This is the brand's top device and designed to be the single gadget required to venture virtually any location and track every activity.

This makes it an extremely expensive proposition, priced from £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 – nearly double the price of the regular Fenix 8.

Users get a significant functionality for your investment, with best-in-class workout, activity and adventure monitoring. The complete offline mapping of the world can seamlessly direct you return to the path if you get lost without a phone, and look excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life despite the display on all the time, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your phone provider, as with other wearables. But unlike competing satellite-capable products, emergency communication is not provided for no cost.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while engaged in jogging, biking or comparable pursuits – plus emergency orbital SOS messaging.

Location updates and texts over satellite are then billed additionally, with higher-tier plans offering different quotas of satellite use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply head out outside minus 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 relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate back and forth via text or spoken messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just a mobile number is enough to register for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set replies you can send to expedite communication. Voice messages and calls perform acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to automatically send a link to selected contacts whenever you start an activity, so they can track your real time position on a map. It’s great for following race performance, 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 generally worked effectively, although the real location has occasionally lagged when transitioning in and out of good LTE coverage.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, though it is essential to remember that satellite coverage is restricted to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options offered via the support portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin offers recycling schemes on new purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of signal.

Outcome is an increasingly remarkable outdoor device for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it is not dependent on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, cycling or hiking, but still desires to be locatable and contactable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, monitors everything with premier GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: very expensive, LTE and satellite features need monthly subscription, restricted Garmin Pay financial compatibility, voice features are slow, basic smartwatch features compared with competing watches.
