The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

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

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new mobile technology, along with an available state-of-the-art microLED screen in a limited edition. This is Garmin's top device and designed to be the only gadget required to explore virtually anywhere and monitor all your movements.

This positions it as an very expensive proposition, starting at £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 display – almost double the cost of the regular Fenix 8.

You do receive a significant functionality for your investment, with industry-leading workout, movement and adventure tracking. The complete offline maps of the globe can automatically guide you return to the trail if you get lost without a phone, and appear great on the large, sharp and super-bright touchscreen.

This 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 big watch for bigger wrists. However the 47mm OLED model as tested does have an extra day of watch battery life despite the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

The company operates its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your phone carrier, as with other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which provides unlimited LTE text and voice messages, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while out running, biking or similar activities – plus emergency satellite SOS messaging.

Location updates and messages via orbital are then charged on top, with higher-tier subscriptions offering different allowances of orbital use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

After you have got it set up, you simply venture the door without your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you can make and take calls, dispatch texts and generally stay connected with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message back and forth using text or spoken messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a phone number is enough to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned responses you can use to speed things up. Voice messages and calls work OK, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to on its own transmit a URL to selected contacts whenever you start an activity, so they can track your real time position on a map. It’s excellent for monitoring race performance, but it mostly serves as a utility for someone you trust to know your location in case something happens. It has generally worked well, though the real location has occasionally lagged when moving in and out of good 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 send texts, position updates and SOS SOS.

A guide shows you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, though it is important to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with options offered through the customer service portal. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital communication, check-in and SOS 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 keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is very liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it is not reliant on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and satellite functions need monthly subscription, restricted Garmin Pay bank support, voice features are sluggish, limited wearable functionality compared with competing watches.
