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

The newest version of the flagship Fenix adventure watch brings a life-saving capability: no-phone communication and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile technology, along with an optional state-of-the-art microLED screen in a limited edition. This is Garmin's top device and engineered to be the only gadget needed to venture virtually anywhere and track all your movements.

This positions it as an very expensive option, starting at £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 display – almost twice the price of the regular Fenix 8.

You do get a lot of functionality for your money, with industry-leading workout, movement and adventure tracking. The full offline mapping of the world can automatically guide you return to the trail if you get lost absent a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the smaller 43mm size found in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite service service instead of depending on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-enabled products, SOS communication is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which provides unlimited LTE text and audio messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while out running, biking or comparable pursuits – plus SOS orbital SOS alerts.

Location updates and texts over orbital are then billed additionally, with more expensive subscriptions including different quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the functionality.

After you have completed setup, you simply venture outside without your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and overall stay connected with your family and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via typed or spoken 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 sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It has a set of personalizable pre-set responses you can use to expedite communication. Voice recordings and calls perform OK, though as with most wearables, you’re not going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to on its own send a link to selected contacts every time you begin an exercise, so they can follow your real time location on a map. It’s excellent for following race progress, but it mostly serves as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically functioned well, though the real location has occasionally been delayed when moving in and out of strong LTE signal.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide displays you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, however it is important to note that satellite coverage is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options offered via the customer service site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused materials. Garmin provides recycling programs on recent purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor device for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

This is very liberating to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone provider so works with any make of smartphone and carrier.

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 still desires to be trackable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED display, tracks all activities with best-in-class GPS, integrated torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and satellite features need monthly subscription, limited Garmin Pay financial support, speech features are slow, limited wearable features compared with competing watches.
