Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Messaging

The latest model of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving capability: phone-free messaging and SOS alerts using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, plus an available state-of-the-art microLED screen in a limited edition. This is Garmin's premier model and engineered to be the single tool needed to explore virtually any location and track every activity.

This positions it as an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the regular Fenix 8.

You do get a significant features for your money, with best-in-class workout, movement and outdoor tracking. The complete offline maps of the globe can automatically direct you return to the path if you lose your way without a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other devices, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed does have an extra day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Texting, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan linked to your mobile carrier, as with other wearables. However unlike Apple or Google's satellite-capable products, emergency communication is not provided for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messages, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in jogging, cycling or comparable pursuits – plus emergency satellite SOS messaging.

Check-ins and texts via satellite are then billed on top, with more expensive subscriptions including various allowances of satellite use, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

After you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you are able to make and take calls, dispatch texts and overall keep in touch with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally using text or voice messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned replies you can send to expedite communication. Voice messages and calls work OK, though as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can configure to on its own send a link to selected contacts whenever you begin an exercise, so they can track your live position on a map. It’s great for following race performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case something happens. It has typically functioned effectively, though the actual position has sometimes lagged when transitioning in and out of strong LTE coverage.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to locate 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 crucial safety feature, though it is essential to note that orbital service is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with options offered through the customer service site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal 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 additional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of signal.

The result is an even more remarkable outdoor tool for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to provide the features. Fortunately it isn’t dependent on your phone carrier so functions with any make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but still wants 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, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in torch, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: very costly, LTE and orbital functions require ongoing payment, limited Garmin Pay bank compatibility, speech capabilities are sluggish, limited smartwatch features versus Apple/Google/Samsung watches.
