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

The most recent iteration of Garmin's flagship Fenix outdoor timepiece introduces a potentially lifesaving feature: no-phone communication and SOS messaging using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating new cellular technology, plus an optional state-of-the-art microLED display in a limited edition. This is the brand's premier device and designed to be the only gadget required to venture virtually anywhere and track all your movements.

That makes it an extremely expensive option, 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 price of the standard Fenix 8.

You do get a significant functionality for your investment, with best-in-class fitness, movement and adventure tracking. Its complete offline mapping of the world can seamlessly direct you return to the path if you get lost absent a phone, and look excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital service service instead of relying on a watch plan tied to your phone provider, like other smartwatches. But unlike competing satellite-capable products, emergency messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while out running, biking or similar activities – along with SOS satellite SOS messaging.

Check-ins and texts via orbital are then charged additionally, with more expensive subscriptions offering different quotas of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you simply head out outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, dispatch texts and generally keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via text or voice communications, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of customisable pre-set replies you can use to expedite communication. Spoken recordings and calls perform acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically transmit a URL to selected contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for following race progress, but it mostly serves as a tool for someone you trust to be aware of your location in case an incident occurs. It has generally worked effectively, though the actual position has occasionally been delayed when moving in and out of good LTE coverage.

All of these features are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, though it is essential to note that satellite service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available through the customer service site. The battery is certified to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin provides recycling 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 optional Garmin inReach service 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 incorporates LTE for messaging, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without coverage.

Outcome is an even more impressive outdoor device for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without needing additional gear.

It is very liberating to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the monthly fee of the inReach service to provide the features. At least it is not reliant 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 dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED display, monitors everything with premier GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital features need monthly subscription, limited Garmin Pay bank support, voice capabilities are sluggish, basic wearable features versus competing watches.
