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

The most recent model of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving feature: phone-free communication and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new cellular tech, plus an available advanced microLED screen in a special edition. This is the brand's premier device and designed to be the single tool required to venture virtually any location and monitor all your movements.

That positions it as an extremely expensive 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 display – almost double the cost of the regular Fenix 8.

Users get a lot of features for your investment, with best-in-class fitness, movement and adventure monitoring. The full offline maps of the world can automatically guide you return to the path if you lose your way absent a phone, and appear excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an extra day of smartwatch battery life even with the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan tied to your phone provider, like other wearables. But unlike competing satellite-capable products, emergency communication is not provided for no cost.

Rather, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messages, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in jogging, cycling or comparable activities – plus SOS satellite SOS alerts.

Location updates and texts over orbital are then charged on top, with higher-tier subscriptions offering various allowances of satellite use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the functionality.

After you have completed setup, you just head out outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to make and take calls, send texts and generally stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or spoken communications, and make voice calls. Your contact is not required to have 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 tiny on-screen keyboard is slow. It has a set of personalizable pre-set responses you can send to speed things up. Voice recordings and calls work OK, although as with the majority of wearables, you’re not going to wish to use it for extended discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own transmit a link to chosen contacts whenever you start an activity, so they can track your real time position on a map. It’s excellent for monitoring competition 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 typically functioned well, though the real location has occasionally lagged when moving in and out of good LTE coverage.

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, position check-ins and emergency SOS.

A guide shows you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, though it is important to remember that satellite coverage is restricted to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services offered via the support portal. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused components. Garmin offers disposal schemes on recent 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re without coverage.

Outcome is an increasingly impressive outdoor tool for those that want to be phone-free. If you want to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

This is very liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to provide the service. At least it is not dependent on your phone carrier so works with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, biking or hiking, but still wants to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks all activities with premier GPS, built-in flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very expensive, LTE and satellite features require monthly payment, limited Garmin Pay financial support, speech features are sluggish, basic smartwatch functionality versus Apple/Google/Samsung watches.
