The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

This latest version of Garmin's premium Fenix adventure timepiece introduces a potentially lifesaving capability: no-phone messaging and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating new cellular tech, along with an optional state-of-the-art microLED screen in a limited edition. It is Garmin's top device and engineered to be the single gadget required to venture virtually anywhere and monitor all your movements.

This makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the standard Fenix 8.

You do get a lot of functionality for your money, with industry-leading workout, activity and outdoor tracking. The complete offline mapping of the globe can seamlessly direct you back to the trail if you get lost absent a phone, and appear excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan tied to your mobile provider, like other smartwatches. However in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in jogging, biking or similar pursuits – along with SOS orbital SOS alerts.

Check-ins and messages via satellite are then billed additionally, with higher-tier plans offering different quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the service.

After you have got it set up, you just venture outside without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, dispatch texts and generally stay connected with your relatives and friends.

When you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message back and forth using text or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is enough to sign up for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable pre-set responses you can use to speed things up. Spoken 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 set it up to on its own transmit a URL to chosen contacts every time you start an exercise, so they can follow your real time location on a map. It’s excellent for following race performance, but it primarily acts as a utility for someone you trust to be aware of your whereabouts in case something happens. It has generally worked well, although the real position has sometimes lagged when moving in and out of strong LTE signal.

All of these features are available 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 updates and emergency SOS.

A on-screen assistance shows you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is important to note that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with services available via the customer service site. The battery is certified to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides disposal schemes on recent purchases.

Cost

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 cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

Outcome is an even more impressive adventure tool for those that desire to be phone-free. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

This is quite liberating to be outdoors without a phone, but that capability carries 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 isn’t dependent on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.
