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

The most recent model of the premium Fenix outdoor timepiece includes a life-saving capability: phone-free messaging and emergency alerts via 4G LTE or satellite connections.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding new mobile tech, along with an available state-of-the-art microLED display in a special edition. It is Garmin's premier model and engineered to be the single gadget needed to explore almost anywhere and monitor every activity.

That positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to 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 significant features for your money, with best-in-class fitness, movement and outdoor monitoring. Its full offline mapping of the world can automatically direct you return to the trail if you lose your way without a phone, and look excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the display always active, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

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

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and voice messages, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while engaged in jogging, cycling or comparable pursuits – along with emergency satellite SOS alerts.

Check-ins and texts over orbital are then billed on top, with more expensive plans including different quotas of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

After you have got it set up, you just head out outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you are able to make and take calls, dispatch texts and generally keep in touch with your relatives and companions.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned responses you can use to expedite communication. Spoken messages and calls work acceptably, although as with most wearables, you’re not going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest feature. You can configure to on its own transmit a link to selected 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 mostly acts as a utility for someone you rely on to know your location in case an incident occurs. It has typically functioned effectively, though the actual position has sometimes lagged when moving in and out of strong LTE coverage.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position 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 messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is important to remember that satellite coverage is restricted to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services offered via the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal programs on recent purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans cost 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 messaging, call functionality and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

It is very freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the service. At least it is not dependent on your phone provider so functions with any brand of smartphone and network.

This 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 locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, monitors everything with premier GPS, integrated flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features require monthly subscription, limited Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch functionality versus competing watches.
