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

This most recent version of Garmin's flagship Fenix outdoor timepiece introduces a life-saving feature: no-phone communication and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED display in a special edition. It is Garmin's top model and designed to be the only tool needed to venture virtually any location and monitor all your movements.

This makes it an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the price of the standard Fenix 8.

Users get a significant features for your investment, with best-in-class fitness, movement and adventure tracking. Its full offline mapping of the globe can automatically guide you return to the path if you lose your way absent a phone, and appear excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as tested boasts an additional day of watch battery life despite the screen always active, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service instead of depending on a watch plan linked to your mobile provider, like other wearables. But in contrast to competing satellite-capable products, SOS messaging is not provided for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while out running, biking or comparable activities – plus SOS orbital SOS alerts.

Check-ins and texts over orbital are then charged on top, with higher-tier subscriptions offering different quotas of orbital use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the functionality.

Once you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and friends.

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 message back and forth using text or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a mobile number is enough to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable canned replies you can send to speed things up. Voice messages and calls work OK, although as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to automatically transmit a URL to chosen contacts whenever you begin an activity, so they can follow your real time position on a map. It’s great for following race performance, but it primarily serves as a utility for someone you rely on to know your location in case something happens. It has generally functioned effectively, though the actual position has occasionally lagged when moving in and out of strong LTE signal.

These features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide displays 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 vital safety feature, however it is important to note that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options offered through the support site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers recycling programs on new 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 cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re without signal.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you from afar while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the colossal cost of the watch and the recurring fee of the inReach service to provide the features. Fortunately it is not reliant on your phone carrier so works with any brand of smartphone and network.

The 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 locatable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and satellite functions need ongoing subscription, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable functionality versus competing watches.
