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

This most recent model of Garmin's premium Fenix outdoor watch includes a life-saving feature: no-phone communication and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new mobile technology, along with an optional advanced microLED display in a special edition. This is Garmin's top model and engineered to be the single gadget needed to explore almost anywhere and monitor all your movements.

That positions it as an very expensive proposition, priced from £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 edition with microLED display – almost twice the price of the regular Fenix 8.

You do get a significant features for your money, with industry-leading fitness, movement and outdoor tracking. The full offline mapping of the world can automatically guide you back to the trail if you get lost absent a phone, and appear excellent on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an additional day of smartwatch battery life even with the display always active, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your phone carrier, as with other smartwatches. However in contrast to competing satellite-capable devices, SOS communication is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in running, cycling or comparable pursuits – along with emergency satellite SOS messaging.

Check-ins and texts via satellite are then billed on top, with higher-tier subscriptions offering different allowances of satellite usage, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the functionality.

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

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally using typed or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable pre-set responses you can send to speed things up. Voice recordings and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can configure to on its own send a link to chosen contacts whenever you begin an exercise, so they can track your live location on a map. It’s excellent for monitoring race progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned well, though the real location has sometimes been delayed when moving in and out of good LTE signal.

These features are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is essential to remember that orbital coverage is restricted to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the support portal. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin offers disposal schemes on new purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re out of signal.

The result is an increasingly remarkable outdoor device for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin does so without needing anything else.

This is very liberating to be outside without a phone, but that functionality carries quite a cost, both in terms of the colossal price of the watch and the recurring fee of the inReach service to provide the features. Fortunately it is not reliant on your phone provider so works with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or hiking, but still desires to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: very expensive, LTE and orbital features need ongoing subscription, restricted Garmin Pay bank support, speech capabilities are sluggish, limited wearable functionality compared with competing watches.
