The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This latest version of Garmin's flagship Fenix adventure watch includes a life-saving feature: phone-free communication and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating new cellular tech, plus an available advanced microLED screen in a limited edition. It is Garmin's premier device and designed to be the single gadget needed to venture virtually anywhere and track all your movements.

That makes it an very pricey proposition, starting at £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 variant with microLED display – nearly twice the price of the standard Fenix 8.

You do receive a significant features for your money, with industry-leading workout, activity and outdoor monitoring. The 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 high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed boasts an extra day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription service rather than depending on a watch plan linked to your phone carrier, like other smartwatches. However unlike competing satellite-enabled products, emergency messaging is not provided for no cost.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack location tracking – so your contacts or family can keep an eye on you while out running, cycling or comparable pursuits – plus emergency orbital SOS messaging.

Location updates and messages via satellite are then billed additionally, with more expensive subscriptions offering different allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you simply head out the door minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you are able to make and take calls, dispatch texts and generally stay connected with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via text or voice messages, and make voice calls. Your contact does not need 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 small on-screen keyboard is time-consuming. It has a set of personalizable canned responses you can send to expedite communication. Voice messages and calls perform acceptably, although as with most smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own send a URL to selected contacts every time you start an exercise, so they can follow your real time location on a map. It’s great for following race progress, but it mostly acts as a tool for someone you trust to be aware of your location in case something happens. It has generally functioned effectively, though the real location has occasionally lagged when moving in and out of strong LTE signal.

All of these features are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide shows you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is important to note that satellite coverage is restricted to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available through the support site. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused components. Garmin provides recycling schemes on recent purchases.

Cost

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).

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re without coverage.

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

It is very liberating to be outside without a phone, but that functionality comes at quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the features. Fortunately it is not dependent on your phone carrier so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, cycling or trekking, but still wants to be locatable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with premier GPS, built-in flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: extremely expensive, LTE and orbital features require monthly payment, restricted Garmin Pay financial compatibility, voice features are slow, limited wearable features compared with Apple/Google/Samsung watches.
