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

The latest version of Garmin's flagship Fenix adventure timepiece includes a potentially lifesaving feature: no-phone communication and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new cellular technology, along with an optional state-of-the-art microLED screen in a limited edition. This is Garmin's premier model and designed to be the only gadget required to explore almost anywhere and monitor all your movements.

This makes it an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the regular Fenix 8.

Users receive a significant functionality for your investment, with best-in-class fitness, activity and adventure monitoring. The full offline maps of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and look great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm size available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of watch battery life despite the display always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than depending on a watch plan tied to your phone provider, like other smartwatches. However unlike competing satellite-enabled devices, SOS messaging is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE SMS and voice messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or similar activities – along with emergency orbital SOS alerts.

Location updates and messages via orbital are then billed additionally, with more expensive subscriptions offering different allowances 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 got it set up, you just venture the door minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you can make and take calls, send texts and overall 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 typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can send to speed things up. Voice recordings and calls perform OK, though as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to on its own send a URL to selected contacts every time you begin an exercise, so they can follow your live location on a map. It’s great for monitoring race progress, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has generally worked effectively, though the real location has sometimes been delayed when transitioning in and out of strong LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide displays you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is essential to remember that satellite service is restricted to the US continent, the majority of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with options available through the customer service site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any recycled components. Garmin provides disposal schemes 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 service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re without coverage.

The result is an even more impressive outdoor tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

It is very liberating to be outdoors without a phone, but that capability carries quite a price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it isn’t reliant on your phone provider so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when running, biking or hiking, but nevertheless wants to be locatable and contactable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and orbital functions need ongoing subscription, limited Garmin Pay bank support, speech features are slow, basic wearable features versus competing watches.
