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

This latest iteration of Garmin's flagship Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge cellular technology, along with an optional advanced microLED screen in a special edition. This is Garmin's top device and engineered to be the single tool needed to explore virtually anywhere and track every activity.

That makes it an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model 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 regular Fenix 8.

Users receive a significant functionality for your money, with industry-leading fitness, movement and outdoor monitoring. The full offline maps of the world can automatically guide you back to the path if you lose your way without a phone, and look excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life even with the display always active, lasting a reliable eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

The company uses its own inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan tied to your phone carrier, as with other wearables. However in contrast to Apple or Google's satellite-capable products, SOS messaging is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in running, biking or similar activities – along with SOS satellite SOS alerts.

Check-ins and texts via orbital are then charged additionally, with more expensive plans including different allowances of satellite usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, send texts and overall stay connected with your relatives and companions.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via typed or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can use to expedite communication. Voice messages and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can set it up to on its own send a link to chosen contacts whenever you start an exercise, so they can track your real time location on a map. It’s great for monitoring competition progress, but it primarily acts as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned effectively, though the real position has occasionally been delayed when transitioning in and out of good LTE coverage.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A guide displays you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, however it is essential to remember that orbital coverage is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services offered via the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch lacks any reused components. Garmin provides disposal programs on recent purchases.

Price

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

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an increasingly impressive adventure device for those that desire to be phone-free. 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 requiring additional gear.

This is very liberating to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to enable the service. Fortunately it isn’t reliant on your phone provider so works with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, cycling or trekking, but nevertheless desires to be locatable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.
