Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Texting

The most recent model of the top-tier Fenix adventure timepiece brings a potentially lifesaving feature: no-phone messaging and emergency alerts via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's top device and designed to be the only gadget needed to venture almost any location and track all your movements.

That positions it as an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost twice the price of the regular Fenix 8.

You do get a lot of features for your investment, with best-in-class fitness, movement and outdoor monitoring. Its full offline maps of the world can automatically guide you back to the trail if you lose your way absent a phone, and appear excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm version found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed does have an extra day of watch battery life despite the display always active, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. However in contrast to competing satellite-enabled products, emergency messaging is not provided for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and audio messages, call functionality and LiveTrack location sharing – so your friends or loved ones can keep an eye on you while out jogging, biking or comparable activities – along with SOS satellite SOS alerts.

Check-ins and messages via orbital are then charged additionally, with higher-tier plans including various quotas of satellite usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have completed setup, you simply venture outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, send texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via typed or spoken messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is enough to register for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can use to speed things up. Spoken messages and calls perform acceptably, though as with most wearables, you’re not going to wish to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a URL to selected contacts whenever you begin an activity, so they can track your real time location on a map. It’s great for monitoring race progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically worked well, though the real position has sometimes been delayed 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 locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, however it is important to remember that satellite service is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the customer service site. The battery is certified to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal schemes on new 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re out of signal.

The result is an increasingly impressive adventure tool 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 requiring anything else.

This is very freeing to be outside without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach service to provide the service. Fortunately it is not dependent on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but still wants to be locatable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED display, monitors everything with best-in-class GPS, built-in torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely costly, LTE and orbital features require monthly subscription, limited Garmin Pay financial compatibility, voice features are slow, limited wearable functionality compared with Apple/Google/Samsung watches.
