The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

This newest version of Garmin's premium Fenix adventure timepiece brings a potentially lifesaving feature: phone-free messaging and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding cutting-edge cellular technology, plus an optional advanced microLED display in a limited edition. It is Garmin's premier model and engineered to be the single gadget required to explore virtually any location and monitor every activity.

That positions it as an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the cost of the standard Fenix 8.

You do get a lot of functionality for your investment, with best-in-class fitness, movement and outdoor tracking. The full offline mapping of the globe can seamlessly guide you back to the path if you get lost absent a phone, and appear excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your mobile provider, as with other smartwatches. But unlike competing satellite-capable devices, emergency messaging is not included for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and audio messages, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while out jogging, cycling or similar activities – along with emergency satellite SOS alerts.

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

After you have got it set up, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and generally stay connected with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using typed or spoken communications, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger app, only a mobile number is enough to register for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set replies you can use to expedite communication. Spoken recordings and calls work OK, although as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the most useful function. You can set it up to automatically 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 great for monitoring competition performance, but it primarily acts as a tool for someone you rely on to know your location in case something happens. It has generally worked effectively, though the actual position has sometimes been delayed when moving in and out of good LTE coverage.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance 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 crucial lifeline, though it is important to remember that orbital service is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options offered through the customer service portal. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on new purchases.

Price

This Fenix 8 Pro is priced 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 builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that want to be unplugged. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is quite liberating to be outside without a phone, but that functionality carries a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it is not reliant on your phone provider so works with any make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking or trekking, but still desires to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors all activities with premier GPS, integrated torch, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and orbital functions require monthly payment, restricted Garmin Pay financial compatibility, speech features are sluggish, limited smartwatch features versus Apple/Google/Samsung watches.
