Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

This latest iteration of Garmin's top-tier Fenix adventure watch introduces a potentially lifesaving feature: no-phone communication and emergency alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an optional advanced microLED display in a limited edition. This is the brand's premier model and engineered to be the only gadget needed to explore almost anywhere and track every activity.

That positions it as an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the price of the regular Fenix 8.

You do get a lot of features for your investment, with best-in-class workout, movement and outdoor monitoring. Its complete offline mapping of the world can seamlessly direct you back to the trail if you get lost absent a phone, and appear great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life despite the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

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

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE SMS and voice messages, calls and LiveTrack location tracking – so your contacts or loved ones can monitor you while engaged in running, cycling or similar activities – along with SOS orbital SOS messaging.

Location updates and texts via satellite are then billed additionally, with more expensive plans including various allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the service.

Once you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you can place and receive calls, dispatch texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally via text or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned replies you can send to expedite communication. Voice messages and calls work OK, although as with the majority of smartwatches, you’re not going to want to use it for extended conversations as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a link to selected contacts every time you begin an activity, so they can track your live position on a map. It’s excellent for monitoring competition performance, but it mostly acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has typically worked effectively, although the actual position has sometimes lagged when transitioning in and out of strong LTE coverage.

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

A on-screen assistance shows you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to remember that satellite coverage is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered via the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal programs on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of signal.

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 remotely while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is quite liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the features. Fortunately it isn’t dependent on your phone carrier so functions with any make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks everything with best-in-class GPS, built-in flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely costly, LTE and satellite functions need monthly payment, limited Garmin Pay financial support, speech features are sluggish, basic wearable functionality versus competing watches.
