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

The latest iteration of the premium Fenix adventure watch brings a life-saving feature: no-phone communication and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, along with an available state-of-the-art microLED screen in a limited edition. It is Garmin's top device and designed to be the single tool needed to venture virtually anywhere and track all your movements.

This positions it as an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost twice the price of the regular Fenix 8.

Users get a lot of functionality for your money, with industry-leading workout, activity and adventure tracking. Its complete offline mapping of the world can seamlessly direct you back to the path if you get lost without a phone, and look excellent on the sizable, sharp and super-bright touchscreen.

The 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. But the 47mm OLED model as reviewed does have an extra day of smartwatch battery life even with the screen always active, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your phone carrier, as with other smartwatches. But unlike Apple or Google's satellite-capable devices, SOS messaging is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE SMS and voice messages, call functionality and LiveTrack position sharing – so your friends or family can monitor you while out running, cycling or comparable pursuits – plus SOS satellite SOS alerts.

Location updates and messages over orbital are then charged on top, with more expensive subscriptions offering various allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have completed setup, you just head out outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to place and receive calls, send texts and overall stay connected with your family and companions.

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 install the Garmin Messenger application, you can then message reciprocally via text or spoken communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of customisable pre-set responses you can use to speed things up. Voice messages and calls work OK, though as with the majority of wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a link to selected contacts whenever you start an activity, so they can follow your real time location on a map. It’s excellent for monitoring race progress, but it primarily serves as a utility for someone you trust to know your location in case an incident occurs. It has typically functioned effectively, though the actual position has sometimes lagged when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide shows 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 straightforward to use and could be a vital safety feature, though it is essential to note that satellite service is restricted to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally repairable with services available through the customer service portal. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal programs on recent 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 plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor tool for those that want to be phone-free. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

This is very freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to enable the features. At least it isn’t dependent on your phone carrier so functions with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, cycling or hiking, but still wants to be locatable and reachable. For everyone else, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, tracks all activities with premier GPS, integrated flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: extremely costly, LTE and orbital functions require ongoing subscription, restricted Garmin Pay financial support, speech features are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
