The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Texting

This latest version of Garmin's flagship Fenix outdoor watch introduces a life-saving feature: no-phone messaging and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by adding new cellular tech, along with an optional advanced microLED screen in a special edition. It is Garmin's top device and engineered to be the only tool required to explore virtually any location and monitor every activity.

That makes it an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the price of the standard Fenix 8.

Users receive a significant functionality for your investment, with industry-leading workout, movement and adventure monitoring. The complete offline mapping of the globe can seamlessly direct you back to the trail if you get lost without a phone, and appear excellent on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed boasts an extra day of watch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company operates its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan tied to your phone provider, like other wearables. But unlike competing satellite-capable products, SOS communication is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which provides unlimited LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while out jogging, cycling or similar pursuits – along with SOS satellite SOS alerts.

Check-ins and messages via orbital are then charged additionally, with more expensive plans offering various quotas of satellite use, climbing 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 completed setup, you simply head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you are able to make and take calls, send texts and overall stay connected with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using typed or voice communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned responses you can use to speed things up. Spoken messages and calls work OK, though as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest feature. You can set it up to automatically send a link to selected contacts every time you start an exercise, so they can track your real time location on a map. It’s excellent for following race progress, but it mostly acts as a utility for someone you trust to be aware of your location in case something happens. It has typically functioned effectively, although the actual position has sometimes been delayed when moving in and out of strong LTE signal.

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

A guide displays 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 crucial safety feature, though it is important to remember that orbital service is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with options offered through the support site. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any reused materials. Garmin offers recycling programs on new purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

Outcome is an increasingly remarkable adventure tool for those that want to be unplugged. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the colossal price of the watch and the monthly fee of the inReach service to enable the features. At least it is not reliant on your phone provider so functions with all 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, biking or hiking, but still wants to be locatable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors everything with premier GPS, integrated torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and orbital functions require ongoing subscription, restricted Garmin Pay bank support, speech features are slow, limited wearable features versus competing watches.
