Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for No-Phone Messaging

The newest iteration of Garmin's top-tier Fenix adventure timepiece includes a potentially lifesaving capability: no-phone messaging and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED screen in a limited edition. It is Garmin's top model and designed to be the only gadget required to venture almost any location and track every activity.

This positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the standard Fenix 8.

You do get a lot of functionality for your investment, with best-in-class fitness, movement and adventure tracking. Its complete offline maps of the globe can seamlessly direct you back to the trail if you get lost absent a phone, and look excellent on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an additional day of watch battery life despite the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your phone provider, as with other wearables. However in contrast to competing satellite-capable products, emergency communication is not included for free.

Rather, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while out jogging, biking or similar pursuits – along with emergency satellite SOS alerts.

Location updates and texts via orbital are then charged on top, with higher-tier plans offering various quotas of orbital use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have completed setup, you simply venture the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via typed or voice messages, and initiate 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.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is slow. It has a set of personalizable pre-set responses you can use to expedite communication. Spoken recordings and calls work acceptably, though as with the majority of smartwatches, you’re not going to wish to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the most useful feature. You can configure to on its own transmit a link to selected contacts whenever you begin an activity, so they can follow your real time location on a map. It’s great for monitoring competition performance, but it mostly serves as a tool for someone you trust to know your location in case an incident occurs. It has typically functioned well, although the actual position has sometimes been delayed when moving in and out of strong LTE signal.

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

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, though it is important to remember that orbital coverage is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options available via the customer service portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused materials. Garmin offers recycling programs 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 service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an even more impressive outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outside without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to provide the service. Fortunately it isn’t reliant on your phone provider so functions with any brand of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, biking or trekking, but still wants to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors everything with best-in-class GPS, integrated torch, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and orbital features require ongoing subscription, limited Garmin Pay financial compatibility, speech features are slow, basic wearable features compared with competing watches.
