Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for No-Phone Texting

This latest version of Garmin's top-tier Fenix outdoor timepiece includes a potentially lifesaving feature: no-phone communication and SOS alerts using 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an available state-of-the-art microLED screen in a limited edition. This is Garmin's top model and engineered to be the only gadget required to venture almost anywhere and monitor all your movements.

This positions it as an very expensive proposition, priced from £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 – nearly double the price of the standard Fenix 8.

Users get a lot of functionality for your investment, with best-in-class workout, movement and adventure tracking. The full offline mapping of the world can automatically direct you back to the path if you get lost absent a phone, and appear excellent on the large, crisp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

The company uses its own inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your phone carrier, as with other smartwatches. However in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not provided for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your contacts or family can monitor you while out running, cycling or similar activities – along with SOS satellite SOS messaging.

Location updates and messages over orbital are then charged additionally, with higher-tier subscriptions offering different allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can test out the functionality.

Once you have got it set up, you just head out outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, send texts and overall stay connected with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can send to speed things up. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can set it up to on its own transmit a link to chosen contacts whenever you begin an activity, so they can track your live position on a map. It’s great for following race performance, but it mostly acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically worked well, though the real location has occasionally lagged when transitioning in and out of good LTE signal.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide shows you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, however it is important to note that orbital coverage is limited to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available through the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal programs on recent 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

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable adventure device for those that desire to be phone-free. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

It is very freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the service. 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 jogging, biking or hiking, but still desires to be locatable and reachable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors all activities with premier GPS, integrated flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital functions need monthly subscription, limited Garmin Pay financial compatibility, voice capabilities are sluggish, limited wearable functionality versus competing watches.
