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

The newest model of Garmin's flagship Fenix adventure watch brings a life-saving feature: phone-free communication and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an available state-of-the-art microLED display in a special edition. It is Garmin's premier device and engineered to be the only gadget required to venture almost any location and track all your movements.

This makes it an extremely pricey option, starting at £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 variant with microLED screen – nearly twice the cost of the regular Fenix 8.

You do receive a significant features for your money, with industry-leading fitness, movement and adventure tracking. The full offline mapping of the world can seamlessly direct you back to the path if you lose your way without a phone, and appear great on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your mobile provider, as with other wearables. However in contrast to competing satellite-enabled products, emergency messaging is not included for no cost.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while engaged in running, cycling or comparable activities – plus SOS satellite SOS messaging.

Location updates and messages over satellite are then charged on top, with more expensive plans including various allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have got it set up, 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 can make and take calls, send texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally via text or voice communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of customisable canned responses you can send to speed things up. Spoken recordings and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to chosen contacts whenever you begin an activity, so they can follow your real time position on a map. It’s great for following competition performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has typically functioned well, although the real location has occasionally lagged 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 does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, 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, though it is essential to remember that satellite service is restricted to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services available via the customer service site. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal programs 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re without signal.

Outcome is an even more remarkable adventure device for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

It is quite freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach service to enable the service. At least it is not reliant on your phone carrier so works with all make of smartphone and carrier.

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

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors all activities with premier GPS, built-in torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and orbital features need ongoing payment, limited Garmin Pay bank compatibility, speech features are slow, basic smartwatch functionality compared with Apple/Google/Samsung watches.
