The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

The latest iteration of Garmin's premium Fenix adventure watch introduces a potentially lifesaving capability: no-phone communication and SOS messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an available state-of-the-art microLED screen in a special edition. This is the brand's top device and engineered to be the only tool needed to venture almost anywhere and track every activity.

That positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the standard Fenix 8.

Users receive a lot of functionality for your money, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the globe can automatically guide you back to the path if you lose your way without a phone, and appear excellent on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life despite the display always active, enduring 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 service plan rather than depending on a watch plan linked to your mobile carrier, as with other wearables. However unlike competing satellite-enabled devices, SOS communication is not provided for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack position tracking – so your contacts or family can monitor you while out jogging, cycling or similar activities – along with emergency satellite SOS messaging.

Location updates and messages via satellite are then billed on top, with more expensive plans offering various allowances of orbital use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have completed setup, you just venture outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, 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 sends 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 via typed or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a phone number is sufficient to sign up for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable canned responses you can use to expedite communication. Spoken messages and calls perform acceptably, although as with the majority of wearables, you’re unlikely going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a URL to chosen contacts whenever you begin an exercise, so they can track your real time position on a map. It’s great for monitoring competition performance, but it mostly serves as a tool for someone you trust to know your location in case an incident occurs. It has generally functioned effectively, although the real position has sometimes lagged when transitioning in and out of strong LTE coverage.

These features are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to note that satellite coverage is limited to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered via the support portal. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled materials. Garmin provides disposal 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is very freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the features. At least it isn’t reliant on your phone provider so functions with any brand of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, cycling or hiking, but still wants to be trackable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very costly, LTE and satellite features require ongoing subscription, limited Garmin Pay financial compatibility, speech features are slow, limited wearable features compared with Apple/Google/Samsung watches.
