Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for Phone-Free Messaging

This latest model of the top-tier Fenix outdoor timepiece brings a potentially lifesaving feature: phone-free messaging and SOS messaging via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating new cellular tech, plus an optional advanced microLED display in a limited edition. This is Garmin's top model and designed to be the single gadget needed to explore virtually any location and track all your movements.

That makes it an very expensive option, priced from £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 screen – nearly 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 mapping of the world can automatically guide you return to the path if you get lost without a phone, and look excellent on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the display on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your mobile provider, like other smartwatches. However in contrast to competing satellite-capable products, emergency messaging is not included for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in running, biking or comparable pursuits – along with emergency satellite SOS alerts.

Location updates and texts over satellite are then billed additionally, with more expensive plans including different allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you just venture outside without your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, dispatch texts and overall keep in touch with your family and companions.

When you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message back and forth via text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, 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 has a collection of personalizable pre-set responses you can send to speed things up. Spoken recordings and calls work OK, although as with most smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a link to chosen contacts every time you begin an activity, so they can follow your live position on a map. It’s great for following race performance, but it mostly acts as a tool for someone you trust to be aware of your location in case an incident occurs. It has generally worked effectively, although the actual position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these features are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A guide displays you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that orbital coverage is restricted to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with services offered via the support site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling schemes on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone provider so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, cycling or hiking, but still wants to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated torch, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay bank support, speech capabilities are slow, limited wearable functionality versus Apple/Google/Samsung watches.
