Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Messaging

The latest iteration of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving capability: phone-free communication and SOS messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new mobile tech, along with an available state-of-the-art microLED screen in a limited edition. This is Garmin's top model and engineered to be the single tool required to venture virtually anywhere and track all your movements.

This makes it an extremely pricey option, starting at £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 variant with microLED display – almost twice the cost of the standard Fenix 8.

You do receive a lot of functionality for your investment, with best-in-class fitness, movement and adventure tracking. The full offline mapping of the world can automatically direct you back to the path if you get lost without a phone, and appear great on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other models, 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 even with the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calls and Real-Time Location

The company uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your mobile carrier, as with other wearables. However unlike competing satellite-capable products, emergency communication is not included for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messages, call functionality and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in jogging, cycling or comparable pursuits – plus SOS satellite SOS alerts.

Check-ins and messages over satellite are then charged on top, with more expensive plans offering different allowances of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you can make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or spoken communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of customisable canned replies you can use to expedite communication. Spoken messages and calls perform acceptably, although as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a link to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s excellent for following race performance, but it primarily acts as a utility for someone you trust to know your location in case an incident occurs. It has typically worked effectively, although the actual position has occasionally lagged when moving 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 lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide shows you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is important to remember that satellite coverage is limited to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with services offered via the customer service site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling schemes on recent purchases.

Price

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

Conclusion

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

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising out at night 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 a significant price, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to enable the service. At least it isn’t reliant on your phone carrier so works with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital functions require monthly subscription, restricted Garmin Pay financial support, voice features are sluggish, basic wearable features compared with Apple/Google/Samsung watches.
