The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

The newest iteration of the premium Fenix adventure timepiece introduces a potentially lifesaving capability: phone-free messaging and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding cutting-edge cellular tech, along with an optional state-of-the-art microLED screen in a special edition. This is the brand's premier device and designed to be the single gadget needed to venture almost any location and track every activity.

That makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the cost of the regular Fenix 8.

Users receive a lot of functionality for your money, with best-in-class fitness, activity and outdoor monitoring. Its full offline maps of the globe can automatically direct you return to the path if you lose your way without a phone, and appear excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested does have an extra day of watch battery life despite the screen on all the time, enduring a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to Apple or Google's satellite-capable products, SOS messaging is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out running, cycling or comparable activities – along with emergency satellite SOS alerts.

Check-ins and messages via orbital are then charged on top, with higher-tier subscriptions offering different allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, you simply venture outside without your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via text or voice messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a phone number is enough to sign up for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It has a set of personalizable canned responses you can send to expedite communication. Spoken messages and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to on its own send a URL to chosen contacts whenever you begin an exercise, so they can follow your real time location on a map. It’s excellent for monitoring competition progress, but it mostly acts as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically worked well, although the real location has sometimes lagged when transitioning in and out of strong LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A on-screen assistance displays you how to find the clear view to the orbital system, which then transmits and gets communications 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 satellite service is limited to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with options offered through the customer service portal. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused components. Garmin offers recycling programs on new purchases.

Cost

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

Conclusion

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re out of signal.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you remotely while running out at night or in the remote areas, the Garmin does so without requiring anything else.

This is very freeing to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to enable the features. Fortunately it isn’t reliant on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but nevertheless desires to be locatable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors everything with best-in-class GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and satellite functions require ongoing payment, restricted Garmin Pay financial compatibility, speech features are slow, basic smartwatch functionality compared with competing watches.
