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

This most recent model of the top-tier Fenix adventure timepiece brings a life-saving feature: phone-free messaging and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available state-of-the-art microLED screen in a special edition. It is the brand's top device and engineered to be the only gadget required to explore virtually any location and track all your movements.

That positions it as an extremely expensive option, starting at £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 variant with microLED screen – nearly twice the cost of the standard Fenix 8.

Users get a lot of functionality for your investment, with industry-leading fitness, movement and adventure tracking. Its full offline mapping of the globe can automatically guide you back to the path if you lose your way absent a phone, and appear great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm size found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed does have an additional day of smartwatch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

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

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, cycling or comparable activities – along with emergency orbital SOS messaging.

Check-ins and messages via satellite are then billed additionally, with higher-tier plans offering various quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you simply venture the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and friends.

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via text or spoken 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.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned replies you can use to speed things up. Spoken recordings and calls work OK, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can configure to automatically send a link to selected contacts whenever you start an activity, so they can track your live location on a map. It’s great for following race performance, but it primarily serves as a tool for someone you trust to be aware of your location in case something happens. It has typically worked well, although the actual location has occasionally lagged when transitioning in and out of strong LTE coverage.

These features are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

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

Sustainability

The watch is typically repairable with services available through the customer service site. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin offers recycling programs on recent purchases.

Cost

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

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable outdoor device for those that want to be unplugged. If you wish to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is very liberating to be outdoors without a phone, but that capability carries quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the service. At least it isn’t dependent on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when running, biking or hiking, but still wants to be trackable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED display, tracks all activities with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and orbital functions need ongoing subscription, limited Garmin Pay bank compatibility, speech features are slow, limited wearable functionality versus Apple/Google/Samsung watches.
