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

The most recent iteration of the flagship Fenix outdoor timepiece includes a potentially lifesaving feature: phone-free messaging and emergency alerts using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge cellular technology, along with an optional advanced microLED display in a limited edition. It is Garmin's top model and engineered to be the single tool needed to explore virtually any location and monitor every activity.

This positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the price of the standard Fenix 8.

Users receive a lot of features for your money, with best-in-class fitness, movement and outdoor monitoring. The complete offline maps of the globe can automatically direct you back to the trail if you lose your way without a phone, and look excellent on the sizable, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version 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 always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

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

Rather, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE text and audio messages, call functionality and LiveTrack position sharing – so your contacts or family can keep an eye on you while engaged in running, cycling or comparable activities – along with SOS satellite SOS messaging.

Check-ins and texts over orbital are then charged additionally, with more expensive plans including various quotas of satellite use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

After you have completed setup, you just head out the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable tasks, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message back and forth via typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a phone number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can use to expedite communication. Voice recordings and calls perform OK, though as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a link to chosen contacts every time you start an exercise, so they can track your live position on a map. It’s great for following race performance, but it primarily acts as a utility for someone you trust to know your location in case an incident occurs. It has typically worked effectively, though the real position has sometimes 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 does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide displays you how to locate the line of sight 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 safety feature, however it is essential to remember that satellite service is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services available via the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin offers recycling schemes on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is quite freeing to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal price of the watch and the monthly fee of the inReach service to provide the features. At least it isn’t reliant on your phone provider so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but still desires to be trackable and reachable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED display, monitors everything with premier GPS, integrated torch, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and satellite functions require monthly payment, limited Garmin Pay bank compatibility, speech capabilities are slow, limited smartwatch functionality compared with Apple/Google/Samsung watches.
