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

This most recent version of Garmin's premium Fenix outdoor timepiece introduces a potentially lifesaving feature: no-phone communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding new cellular tech, plus an optional state-of-the-art microLED display in a limited edition. It is Garmin's premier model and designed to be the only tool needed to explore almost any location and track all your movements.

That makes it an very pricey option, 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 screen – nearly twice the price of the regular Fenix 8.

Users get a lot of functionality for your money, with best-in-class workout, activity and outdoor monitoring. Its complete offline maps of the globe can automatically guide you back to the path if you get lost absent a phone, and look great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a big watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of smartwatch battery life despite the screen on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your phone carrier, as with other wearables. But in contrast to competing satellite-enabled products, emergency communication is not included for free.

Instead, plans start at £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messages, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while out jogging, biking or comparable pursuits – plus emergency satellite SOS alerts.

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

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

When you message someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using text or spoken communications, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable canned replies you can use to expedite communication. Spoken recordings and calls perform OK, although as with most smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to chosen contacts every time you start an exercise, so they can track your real time position on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has typically worked effectively, though the actual position has sometimes been delayed when transitioning in and out of strong LTE signal.

These features are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, however it is essential to note that satellite coverage is limited to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services available through 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 offers recycling programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re out of coverage.

Outcome is an increasingly impressive outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is very freeing to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the features. At least it is not reliant 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 burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, monitors all activities with premier GPS, built-in torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: extremely costly, LTE and orbital functions require monthly payment, restricted Garmin Pay bank compatibility, voice features are slow, basic wearable functionality compared with Apple/Google/Samsung watches.
