Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Texting

The newest iteration of Garmin's premium Fenix adventure timepiece includes a life-saving capability: no-phone communication and SOS messaging via 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge mobile tech, plus an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier model and designed to be the single gadget required to explore virtually any location and track every activity.

This makes it an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the standard Fenix 8.

Users receive a significant functionality for your money, with industry-leading workout, activity and outdoor tracking. Its complete offline mapping of the world can automatically direct you return to the trail if you get lost absent a phone, and look excellent on the large, sharp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an extra day of watch battery life despite the screen always active, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your mobile provider, as with other smartwatches. But unlike Apple or Google's satellite-enabled devices, SOS messaging is not provided for free.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE text and audio messages, calls and LiveTrack position tracking – so your friends or family can keep an eye on you while engaged in jogging, cycling or similar activities – plus SOS satellite SOS alerts.

Location updates and messages via orbital are then billed on top, with more expensive subscriptions offering different allowances of satellite use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you just head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you can place and receive 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 directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via text or spoken messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, 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 has a set of personalizable pre-set responses you can send to speed things up. Spoken recordings and calls work OK, though as with most wearables, you’re not going to want to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the handiest feature. You can configure to automatically transmit a URL to selected contacts whenever you start an exercise, so they can track your real time position on a map. It’s great for monitoring competition progress, but it primarily acts as a tool for someone you rely on to know your whereabouts in case something happens. It has typically functioned effectively, although the real location has occasionally been delayed when moving in and out of strong LTE coverage.

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

A on-screen assistance shows you how to find the line of sight 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 safety feature, however it is important to note that satellite service is restricted to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the support portal. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused materials. Garmin provides recycling schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable adventure tool for those that desire to be phone-free. If you want to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the features. Fortunately it is not dependent on your phone provider so works with any make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks everything with best-in-class GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: very costly, LTE and orbital features need monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, basic smartwatch features compared with Apple/Google/Samsung watches.
