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

This most recent model of the flagship Fenix adventure timepiece brings a potentially lifesaving capability: phone-free messaging and emergency messaging using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge mobile tech, plus an optional state-of-the-art microLED screen in a special edition. It is the brand's premier device and designed to be the only gadget needed to venture almost anywhere and monitor every activity.

This makes it an extremely expensive proposition, starting at £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 variant with microLED display – almost twice the cost of the standard Fenix 8.

You do get a lot of features for your investment, with best-in-class workout, movement and adventure tracking. Its complete offline mapping of the globe can automatically direct you back to the trail if you lose your way without a phone, and appear great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other models, so it is a large watch for bigger wrists. But 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 Messaging, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your mobile provider, as with other wearables. But in contrast to competing satellite-capable devices, emergency messaging is not included for free.

Rather, subscriptions start at £7.99 or similar a month, which provides limitless LTE text and voice messages, calls and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in running, cycling or similar activities – plus SOS orbital SOS alerts.

Location updates and messages via orbital are then billed on top, with higher-tier plans offering various quotas of orbital usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the service.

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

When you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth using typed or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a phone number is enough to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set responses you can send to expedite communication. Voice recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to automatically send a URL to selected contacts whenever you begin an activity, so they can follow your real time position on a map. It’s great for following race performance, but it primarily acts as a utility for someone you rely on to know your location in case an incident occurs. It has generally functioned well, though the real position has occasionally lagged when moving in and out of strong LTE coverage.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins 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, however it is important to note that satellite service is restricted to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered through the customer service site. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of coverage.

The result is an even more impressive adventure device for those that want to be unplugged. If you want to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it isn’t reliant on your phone carrier so works with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, cycling or hiking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors everything with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Drawbacks: very costly, LTE and satellite functions need ongoing subscription, restricted Garmin Pay financial compatibility, voice capabilities are slow, limited wearable functionality compared with competing watches.
