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

This most recent model of the flagship Fenix adventure watch brings a potentially lifesaving capability: no-phone communication and SOS alerts using 4G LTE or orbital links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular tech, along with an available advanced microLED screen in a limited edition. This is the brand's premier model and designed to be the single gadget needed to explore virtually anywhere and monitor all your movements.

That positions it as an very expensive option, starting at £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 edition with microLED screen – nearly double the cost of the standard Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading workout, activity and outdoor tracking. Its complete offline maps of the globe can automatically direct you return to the trail if you lose your way without a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other models, so it is a big watch for larger wrists. However the 47mm OLED version as tested boasts an additional day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

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

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and audio messaging, calls and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – plus SOS orbital SOS messaging.

Location updates and texts via orbital are then charged additionally, with more expensive subscriptions including various quotas of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you just venture 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, dispatch texts and overall stay connected with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally using text or spoken communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a phone number is sufficient to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can use to expedite communication. Spoken recordings and calls perform acceptably, though as with most wearables, you’re not going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own send a link to chosen contacts every time 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 serves as a tool for someone you rely on to be aware of your location in case something happens. It has generally worked effectively, although the real position has sometimes been delayed when transitioning in and out of good LTE signal.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital 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 satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, however it is important to remember that satellite service is limited to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with options available through the customer service portal. 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 offers recycling programs on recent 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re out of signal.

The result is an increasingly remarkable outdoor tool for those that desire to be unplugged. If you wish to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin does so without needing additional gear.

It is quite liberating to be outdoors without a phone, but that capability carries a significant cost, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it is not dependent on your phone carrier so works with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, cycling or hiking, but nevertheless wants to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 already exists.
