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

This newest model of Garmin's top-tier Fenix adventure timepiece includes a life-saving feature: no-phone communication and emergency messaging via 4G LTE or orbital connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating new cellular technology, plus an available state-of-the-art microLED display in a limited edition. It is the brand's premier device and designed to be the only tool required to venture virtually any location and track every activity.

That positions it as an very pricey proposition, 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 edition with microLED display – nearly double the cost of the regular Fenix 8.

Users receive a significant features for your investment, with industry-leading workout, activity and adventure tracking. The full offline maps of the globe can seamlessly guide you return to the path if you get lost without a phone, and look excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the smaller 43mm size available in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the display always active, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your mobile provider, like other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, SOS communication is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack position sharing – so your contacts or family can monitor you while out jogging, biking or comparable pursuits – along with SOS satellite SOS messaging.

Location updates and messages via orbital are then billed additionally, with more expensive plans including various allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a phone number is sufficient to register for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable pre-set responses you can use to speed things up. Spoken messages and calls perform OK, although as with most wearables, you’re not going to wish to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can set it up to automatically transmit a link to chosen contacts whenever you begin an activity, so they can track your real time location on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically functioned effectively, though the real position has sometimes lagged when moving in and out of strong LTE signal.

All of these features are available on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide displays you how to find the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is essential to note that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services available via the support site. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled materials. Garmin offers disposal programs on new purchases.

Price

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

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly remarkable adventure tool for those that desire to be phone-free. If you wish to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is very liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone provider so functions with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, biking or trekking, but still desires to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and satellite messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital features need ongoing subscription, limited Garmin Pay bank support, voice features are slow, basic wearable features versus Apple/Google/Samsung watches.
