Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Texting

This newest model of Garmin's top-tier Fenix outdoor watch introduces a potentially lifesaving feature: no-phone communication and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by adding new mobile tech, along with an optional state-of-the-art microLED screen in a limited edition. This is the brand's premier device and engineered to be the single gadget needed to explore almost any location and monitor every activity.

That positions it as an extremely 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 edition with microLED display – almost twice the cost of the standard Fenix 8.

You do get a significant functionality for your investment, with best-in-class workout, movement and adventure tracking. The full 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, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, 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 on all the time, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your phone provider, as with other wearables. But unlike Apple or Google's satellite-capable devices, SOS communication is not provided for no cost.

Rather, subscriptions start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while out jogging, biking or comparable pursuits – plus SOS orbital SOS alerts.

Check-ins and messages over satellite are then billed additionally, with more expensive subscriptions 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 completed setup, you just venture the door without your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you are able to make and take calls, dispatch texts and generally keep in touch with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random 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 via text or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a phone number is sufficient to sign up for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned replies you can send to speed things up. Voice messages and calls work acceptably, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to selected contacts whenever you start an exercise, so they can track your real time position on a map. It’s excellent for following competition performance, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned effectively, though the actual location has sometimes lagged when moving in and out of strong LTE coverage.

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

A on-screen assistance displays you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is important to note that orbital service is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options available via the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides disposal schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of coverage.

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 remote areas, the Garmin accomplishes this without needing anything else.

It is quite freeing to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to enable the features. Fortunately it isn’t dependent on your phone provider so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be locatable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED display, tracks all activities with best-in-class GPS, built-in torch, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely expensive, LTE and satellite features need monthly subscription, restricted Garmin Pay bank support, voice capabilities are slow, limited wearable functionality compared with competing watches.
