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

The most recent version of the flagship Fenix adventure watch brings a potentially lifesaving capability: phone-free messaging and SOS alerts using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available advanced microLED display in a special edition. It is Garmin's premier device and designed to be the single gadget required to venture virtually any location and monitor every activity.

That positions it as an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the price of the regular Fenix 8.

Users get a significant features for your investment, with best-in-class workout, movement and outdoor monitoring. The complete offline mapping of the globe can automatically guide you return to the path if you get lost without a phone, and look excellent on the sizable, sharp and super-bright display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an extra day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan linked to your mobile provider, like other smartwatches. However unlike competing satellite-capable products, emergency messaging is not provided for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while out running, cycling or comparable activities – plus SOS orbital SOS alerts.

Check-ins and messages via satellite are then charged additionally, with more expensive subscriptions offering different allowances of satellite use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

Once you have completed setup, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, send texts and generally 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 install the Garmin Messenger app, you can then message back and forth via text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable pre-set replies you can use to speed things up. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a URL to chosen contacts every time you begin an exercise, so they can follow your live position on a map. It’s excellent for monitoring competition progress, but it primarily acts as a tool for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned well, although the actual position has sometimes been delayed when transitioning in and out of strong LTE coverage.

These capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide shows you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is essential to remember that satellite coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services available through the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal schemes on recent purchases.

Cost

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 takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re without coverage.

Outcome is an even more impressive adventure device for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very freeing to be outside without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to enable the service. Fortunately it is not dependent on your phone provider so works with all brand of smartphone and carrier.

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