Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The latest model of Garmin's flagship Fenix adventure timepiece introduces a potentially lifesaving feature: phone-free messaging and SOS alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating cutting-edge mobile technology, along with an optional state-of-the-art microLED screen in a limited edition. This is Garmin's top model and engineered to be the only tool needed to venture virtually any location and track every activity.

This positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the cost of the standard Fenix 8.

You do receive a lot of features for your investment, with industry-leading workout, activity and adventure tracking. Its full offline mapping of the world can seamlessly guide you back to the trail if you get lost without a phone, and appear great on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other models, so it is a big watch for larger wrists. But the 47mm OLED version as tested does have an additional day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Texting, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan linked to your phone carrier, like other wearables. However in contrast to Apple or Google's satellite-enabled devices, emergency messaging is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides limitless LTE SMS and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – plus emergency satellite SOS messaging.

Location updates and messages over orbital are then billed on top, with more expensive subscriptions including different allowances of satellite use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you just venture outside without 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 make and take calls, send 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 directly to your watch. If they install the Garmin Messenger app, you can then message back and forth using text or spoken communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a phone number is enough to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can use to expedite communication. Voice recordings and calls work acceptably, though as with the majority of wearables, you’re not going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful function. You can set it up to automatically send a link to chosen contacts every time you begin an activity, so they can follow your live location on a map. It’s great for following competition performance, but it primarily serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has generally worked well, though the actual position has sometimes been delayed when transitioning in and out of good LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is essential to remember that orbital service is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services available via the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers recycling schemes on new 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 subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re without signal.

The result is an increasingly impressive outdoor tool for those that want to be unplugged. If you want to have someone monitor you from afar while running out at night or in the remote areas, the Garmin accomplishes this without needing anything else.

This is very liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone provider so functions with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still wants to be trackable and reachable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very costly, LTE and orbital functions need monthly payment, restricted Garmin Pay bank compatibility, voice capabilities are slow, limited wearable features versus Apple/Google/Samsung watches.
