Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for No-Phone Texting

This newest model of the flagship Fenix outdoor watch brings a potentially lifesaving feature: no-phone communication and emergency alerts using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating new cellular technology, plus an optional state-of-the-art microLED display in a limited edition. This is Garmin's premier device and engineered to be the only tool required to explore virtually anywhere and track every activity.

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

You do receive a lot of features for your investment, with industry-leading workout, activity and outdoor tracking. Its full offline mapping of the globe can seamlessly guide you back to the path if you lose your way absent a phone, and look excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version 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 charges.

Phone-Free Texting, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan linked to your phone provider, like other wearables. However unlike competing satellite-enabled products, emergency communication is not provided for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in running, biking or comparable activities – along with SOS satellite SOS messaging.

Check-ins and messages via orbital are then billed on top, with higher-tier subscriptions including various allowances of satellite use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you simply head out outside minus your phone and the watch will link to LTE. You can not use it for streaming music or similar activities, but you are able to make and take calls, dispatch texts and overall keep in touch with your relatives and companions.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth using typed or spoken communications, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just a mobile number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls work OK, though as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can set it up to on its own send a link to chosen contacts whenever you begin an activity, so they can track your live position on a map. It’s excellent for following competition progress, but it primarily acts as a utility for someone you rely on to know your location in case an incident occurs. It has generally functioned effectively, although the actual position has sometimes been delayed when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A on-screen assistance displays you how to find the clear view 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 lifeline, though it is essential to remember that orbital service is limited to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with services offered via the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal 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 optional Garmin inReach subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable adventure tool for those that desire to be unplugged. If you want to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

It is quite liberating to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to enable the features. At least it is not dependent on your phone carrier so functions with all make 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 trekking, but nevertheless wants to be trackable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with best-in-class GPS, integrated torch, phone and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: very expensive, LTE and satellite functions need ongoing subscription, restricted Garmin Pay bank compatibility, voice capabilities are slow, limited smartwatch functionality compared with Apple/Google/Samsung watches.
