The Fenix 8 Pro Analysis: Integrated LTE and Orbital Connectivity for No-Phone Messaging

The most recent model of Garmin's premium Fenix outdoor timepiece brings a life-saving capability: no-phone messaging and emergency messaging via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile tech, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's top device and engineered to be the only tool required to venture virtually anywhere 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 model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the cost of the standard Fenix 8.

Users get a significant functionality for your investment, with industry-leading workout, movement and adventure tracking. Its complete offline maps of the globe can automatically direct you return to the path if you lose your way without a phone, and appear excellent on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as tested does have an additional day of smartwatch battery life despite the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your phone provider, like other wearables. But in contrast to Apple or Google's satellite-capable devices, SOS messaging is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack location sharing – so your contacts or family can monitor you while out running, cycling or comparable activities – plus emergency orbital SOS messaging.

Location updates and texts over orbital are then billed additionally, with more expensive subscriptions including various allowances of orbital usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you just head out the door minus your phone and the watch will connect 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.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or spoken messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can use to speed things up. Spoken recordings and calls perform OK, though as with most smartwatches, you’re unlikely going to want to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to on its own send a URL to selected contacts every time you start an activity, so they can track your real time location on a map. It’s excellent for monitoring competition progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has typically worked well, though the real position has sometimes lagged when transitioning in and out of strong LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins and emergency SOS.

A guide shows you how to find the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is essential to remember that satellite coverage is restricted to the US continent, most of Canada, and the majority of Europe except for regions 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 capacity after two years of regular charging. The watch does not contain any recycled components. Garmin provides disposal programs on new purchases.

Cost

The 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

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of signal.

The result is an increasingly impressive outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin does so without needing anything else.

This is very freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the service. At least it is not reliant on your phone provider so works with any brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or hiking, but nevertheless desires to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED display, tracks everything with best-in-class GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital functions require monthly payment, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, basic smartwatch functionality versus competing watches.
