Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Messaging

The most recent version of Garmin's premium Fenix adventure timepiece includes a potentially lifesaving capability: phone-free communication and SOS alerts using 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new mobile technology, along with an optional advanced microLED screen in a limited edition. This is Garmin's premier device and designed to be the single tool needed to venture virtually any location and track all your movements.

That positions it as an extremely expensive option, priced from £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 variant with microLED screen – almost twice the price of the standard Fenix 8.

Users get a lot of features for your investment, with industry-leading fitness, movement and adventure monitoring. Its full offline maps of the world can seamlessly guide you back to the trail if you get lost without a phone, and look great on the sizable, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your phone provider, as with other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while out running, cycling or similar activities – plus SOS satellite SOS messaging.

Location updates and messages via satellite are then billed additionally, with more expensive subscriptions including different quotas of satellite usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you just venture outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and generally keep in touch with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using text or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable canned responses you can send to speed things up. Spoken recordings and calls perform OK, although as with the majority of smartwatches, you’re not going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a link to selected contacts whenever you begin an activity, so they can follow your real time location on a map. It’s excellent for monitoring race performance, but it primarily acts as a utility for someone you trust to know your location in case something happens. It has typically functioned well, although the real position has sometimes lagged when moving in and out of good LTE coverage.

All of these features are available 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 check-ins and emergency SOS.

A on-screen assistance shows you how to find 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 crucial safety feature, however it is important to note that satellite service is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services available via the support portal. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled materials. Garmin offers recycling schemes on recent purchases.

Price

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

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of coverage.

The result is an increasingly impressive adventure device for those that want to be unplugged. If you want to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is quite liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to enable the service. At least it isn’t dependent on your phone provider so works with any brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.
