The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Texting

This latest version of Garmin's top-tier Fenix outdoor watch includes a life-saving feature: phone-free messaging and SOS messaging using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, along with an optional advanced microLED screen in a limited edition. This is the brand's top model and engineered to be the single gadget needed to venture almost anywhere and monitor all your movements.

This makes it an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the standard Fenix 8.

You do receive a significant functionality for your money, with industry-leading fitness, movement and adventure tracking. Its complete offline mapping of the world can seamlessly direct you return to the trail if you lose your way absent a phone, and appear great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm version found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life despite the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than depending on a watch plan linked to your mobile carrier, like other smartwatches. But in contrast to competing satellite-capable devices, SOS communication is not included for free.

Instead, plans begin from £7.99 or similar a month, which provides limitless LTE text and audio messages, call functionality and LiveTrack location sharing – so your contacts or family can monitor you while engaged in running, cycling or comparable activities – along with SOS orbital SOS alerts.

Check-ins and texts over satellite are then charged additionally, with more expensive plans including various allowances of orbital use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you just venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you are able to place and receive calls, send texts and overall keep in touch with your family and friends.

Whenever you message 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 app, you can then communicate back and forth using text or spoken communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can send to speed things up. Spoken recordings and calls work acceptably, though as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to automatically transmit a URL to chosen contacts whenever you start an exercise, so they can track your live position on a map. It’s great for following competition performance, but it primarily acts as a utility for someone you rely on to know your location in case something happens. It has typically worked effectively, although the actual location has sometimes lagged when moving in and out of good LTE signal.

All of these capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A guide shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, however it is important to note that orbital service is limited to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically repairable with options available through the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused materials. Garmin offers disposal schemes on new purchases.

Price

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 takes a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re out of signal.

The result is an increasingly impressive adventure tool for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

This is very freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to provide the features. At least it is not reliant on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still desires to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED screen, tracks everything with premier GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: very costly, LTE and orbital functions need ongoing payment, limited Garmin Pay financial compatibility, speech features are slow, basic smartwatch features versus competing watches.
