Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Texting

This newest model of Garmin's top-tier Fenix adventure timepiece includes a potentially lifesaving feature: phone-free communication and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding cutting-edge cellular technology, plus an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier model and engineered to be the single gadget required to explore almost anywhere and monitor every activity.

This makes it an extremely expensive option, priced from £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 edition with microLED screen – nearly double the cost of the regular Fenix 8.

You do get a significant functionality for your money, with industry-leading workout, activity and adventure tracking. The complete offline mapping of the world can automatically direct you back to the path if you get lost without a phone, and look great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm size found in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your mobile carrier, as with other wearables. But unlike competing satellite-enabled products, SOS communication is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE text and voice messaging, call functionality and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in jogging, cycling or comparable pursuits – plus SOS orbital SOS messaging.

Check-ins and texts over satellite are then billed on top, with higher-tier plans including various allowances of orbital use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can evaluate the service.

After you have got it set up, you simply venture the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable tasks, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via text or spoken messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can send to speed things up. Spoken recordings and calls work acceptably, though as with the majority of wearables, you’re not going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the most useful function. You can configure to automatically transmit a link to chosen contacts every time you begin an activity, so they can follow your real time position on a map. It’s excellent for monitoring competition performance, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically functioned well, although the actual location has sometimes been delayed when moving in and out of strong LTE coverage.

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

A guide shows you how to find the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is important to note that orbital 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 typically serviceable with options offered via the support portal. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal programs 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 subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive adventure device for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is quite liberating to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to enable the features. At least it isn’t reliant on your phone provider so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but still desires to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, tracks everything with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite features require monthly payment, restricted Garmin Pay bank support, voice features are sluggish, basic wearable functionality compared with Apple/Google/Samsung watches.
