Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for No-Phone Texting

The most recent version of the flagship Fenix adventure timepiece brings a potentially lifesaving feature: no-phone communication and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new cellular technology, plus an optional advanced microLED display in a limited edition. This is Garmin's premier model and engineered to be the only gadget required to explore virtually anywhere and track all your movements.

This positions it as an very pricey option, starting at £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 cost of the regular Fenix 8.

Users receive a lot of features for your money, with best-in-class fitness, activity and adventure tracking. The full offline maps of the globe can automatically direct you return to the path if you lose your way absent a phone, and appear great on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life even with the screen always active, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite service service instead of depending on a watch plan linked to your mobile provider, like other smartwatches. However unlike Apple or Google's satellite-enabled devices, emergency messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes unlimited LTE text and audio messages, call functionality and LiveTrack location sharing – so your contacts or family can monitor you while engaged in running, biking or similar activities – along with emergency satellite SOS alerts.

Check-ins and texts via satellite are then billed additionally, with more expensive plans including different quotas of satellite usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the service.

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

When you message someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or spoken messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a phone number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable canned responses you can use to speed things up. Spoken recordings and calls perform acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to on its own send a URL to chosen contacts whenever you start an activity, so they can track your live position on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally functioned well, although the actual position has occasionally lagged when transitioning in and out of strong LTE coverage.

These features are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is important to remember that orbital coverage is restricted to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services available through the support site. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any reused materials. Garmin provides recycling programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to enable the features. At least it isn’t reliant on your phone carrier so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, cycling or trekking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated torch, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and satellite features require ongoing subscription, limited Garmin Pay financial support, speech features are slow, basic wearable features compared with Apple/Google/Samsung watches.
