Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Texting

This newest iteration of the premium Fenix outdoor watch brings a potentially lifesaving capability: phone-free messaging and emergency alerts using 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding new cellular tech, along with an optional state-of-the-art microLED display in a special edition. This is the brand's premier device and engineered to be the only tool needed to explore almost anywhere and track every activity.

That makes it an very pricey 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 – almost double the cost of the standard Fenix 8.

You do receive a significant features for your investment, with best-in-class fitness, activity and outdoor monitoring. Its full offline maps of the globe can seamlessly direct you back to the trail if you lose your way absent a phone, and appear excellent on the sizable, sharp and high-luminance touchscreen.

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

No-Phone Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan linked to your mobile carrier, like other smartwatches. But unlike Apple or Google's satellite-enabled devices, SOS messaging is not provided for no cost.

Rather, plans begin from £7.99 or equivalent a month, which provides limitless LTE text and audio messaging, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while out jogging, cycling or comparable activities – plus emergency orbital SOS alerts.

Check-ins and messages over orbital are then charged additionally, with more expensive subscriptions including different quotas of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just head out the door minus your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you are able to place and receive calls, send texts and generally stay connected with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a mobile number is enough to register for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is slow. It has a collection of personalizable pre-set replies you can send to expedite communication. Voice recordings and calls perform OK, although as with most wearables, you’re not going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to automatically send a URL to selected contacts whenever you start an exercise, so they can track your live position on a map. It’s great for following competition performance, but it primarily serves as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally worked well, although the real position has sometimes lagged when moving in and out of strong LTE signal.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide shows you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with services offered via the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused components. Garmin offers recycling programs on recent purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of signal.

Outcome is an even more remarkable adventure device for those that desire to be unplugged. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outside without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to enable the service. At least it is not dependent on your phone provider so works with any make of smartphone and network.

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