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

This latest model of the premium Fenix outdoor watch introduces a life-saving capability: phone-free communication and emergency messaging using 4G LTE or satellite connections.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular tech, along with an optional state-of-the-art microLED screen in a special edition. This is the brand's top device and designed to be the single gadget needed to venture almost any location and monitor all your movements.

This makes it an very expensive option, 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 screen – almost twice the cost of the regular Fenix 8.

Users receive a significant features for your money, with industry-leading workout, movement and adventure monitoring. The full offline maps of the world can seamlessly direct you return to the path if you get lost without a phone, and look excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm version found in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital service plan instead of relying on a watch plan tied to your phone provider, like other smartwatches. But unlike Apple or Google's satellite-capable devices, emergency messaging is not included for free.

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in jogging, biking or similar activities – along with SOS orbital SOS messaging.

Location updates and texts over orbital are then billed additionally, with higher-tier subscriptions offering different quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the service.

Once you have got it set up, you just head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It has a collection of customisable pre-set responses you can use to speed things up. Voice messages and calls work OK, though as with the majority of smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful function. You can configure to automatically transmit a URL to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s great for following competition progress, but it mostly acts as a utility for someone you rely on to be aware of your location 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.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance shows you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is essential to remember that satellite service is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered through the customer service site. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal schemes on new purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

The result is an even more impressive adventure device for those that want to be phone-free. If you want to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite liberating to be outside without a phone, but that capability carries quite a price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to provide the service. At least it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless wants to be locatable and contactable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED screen, tracks all activities with premier GPS, built-in torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital functions need ongoing payment, restricted Garmin Pay bank support, speech capabilities are slow, limited wearable features compared with Apple/Google/Samsung watches.
