The Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

The most recent iteration of the top-tier Fenix adventure watch brings a potentially lifesaving feature: phone-free messaging and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new cellular technology, plus an optional advanced microLED display in a limited edition. This is Garmin's premier device and engineered to be the only gadget needed to venture almost anywhere and monitor all your movements.

This positions it as an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the price of the regular Fenix 8.

You do get a significant functionality for your money, with best-in-class fitness, movement and outdoor monitoring. Its complete offline maps of the world can automatically direct you back to the path if you get lost without a phone, and appear great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-capable products, emergency messaging is not provided for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messages, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in jogging, cycling or comparable activities – plus SOS orbital SOS alerts.

Check-ins and texts over orbital are then charged on top, with more expensive subscriptions including different allowances of orbital use, climbing to a £50 a month all-inclusive plan. 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 outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to place and receive calls, send texts and overall keep in touch with your family and friends.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, just a phone number is sufficient to sign up for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can send to expedite communication. Spoken messages and calls work acceptably, though as with the majority of wearables, you’re not going to want to use it for extended discussions 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 whenever you begin an activity, so they can track your live location on a map. It’s excellent for monitoring race progress, but it primarily acts as a utility for someone you trust to know your location in case something happens. It has typically worked effectively, although the real position has occasionally been delayed when transitioning in and out of strong LTE signal.

These features are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance shows 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 straightforward to use and could be a vital lifeline, though it is essential to note that orbital service is limited to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with services available via the support site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

This Fenix 8 Pro costs 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 builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable adventure tool for those that want to be unplugged. If you want to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is quite liberating to be outside without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach service to enable the features. At least it isn’t dependent on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, super-bright OLED screen, tracks everything with best-in-class GPS, integrated flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital functions require monthly payment, limited Garmin Pay financial compatibility, speech capabilities are slow, basic wearable features versus Apple/Google/Samsung watches.
