Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Messaging

This latest model of Garmin's premium Fenix adventure watch brings a life-saving capability: phone-free communication and emergency messaging using 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding new cellular tech, plus an optional state-of-the-art microLED screen in a limited edition. This is Garmin's top model and engineered to be the only tool needed to explore virtually anywhere and monitor all your movements.

This positions it as an very pricey proposition, priced from £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 display – almost twice the cost of the regular Fenix 8.

Users receive a significant functionality for your investment, with best-in-class fitness, activity and outdoor tracking. The full offline mapping 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, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as tested does have 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 operates its own inReach LTE (4G) and orbital subscription service instead of depending on a watch plan linked to your mobile carrier, like other smartwatches. But in contrast to competing satellite-enabled products, emergency communication is not included for free.

Rather, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messaging, calls and LiveTrack location sharing – so your friends or family can monitor you while out running, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and texts via satellite are then charged additionally, with more expensive subscriptions offering different quotas of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you just venture the door without your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install 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, just a mobile number is enough to register for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can send to speed things up. Voice recordings and calls work OK, although as with most smartwatches, you’re not going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a link to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s excellent for following race progress, but it mostly serves as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned well, although the real location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these features are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide shows you how to locate the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is essential to note that satellite service is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services available via the customer service site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling programs on recent purchases.

Price

This 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

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

The result 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 from afar while running after dark 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 comes at a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when running, biking or trekking, but nevertheless wants to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.
