The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for Phone-Free Messaging

The newest model of the premium Fenix outdoor timepiece includes a potentially lifesaving capability: phone-free communication and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge mobile technology, plus an available advanced microLED display in a special edition. It is the brand's top device and engineered to be the only gadget needed to venture virtually any location and track every activity.

This positions it as an very expensive 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 variant with microLED screen – nearly double the cost of the standard Fenix 8.

You do get a significant features for your money, with industry-leading workout, activity and outdoor monitoring. Its full offline maps of the world can seamlessly guide you return to the trail if you get lost without a phone, and appear excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life despite the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan linked to your mobile provider, as with other smartwatches. But in contrast to competing satellite-enabled products, SOS communication is not included for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in jogging, cycling or comparable pursuits – plus SOS orbital SOS alerts.

Check-ins and messages over orbital are then billed additionally, with more expensive subscriptions offering different quotas of orbital usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the service.

Once you have completed setup, you just head out outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you can place and receive calls, send texts and overall stay connected with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned responses you can send to speed things up. Spoken recordings and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a link to chosen contacts every time you start an activity, so they can follow your live location on a map. It’s excellent for following race progress, but it mostly 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 actual position has occasionally been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide shows you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial 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 parts of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with options offered through the support site. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch lacks any reused materials. Garmin provides disposal programs on new purchases.

The result 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 remote areas, the Garmin accomplishes this without requiring additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to enable the features. Fortunately it isn’t reliant on your phone provider so works with any make of smartphone and network.
