Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Messaging

The latest version of Garmin's premium Fenix outdoor timepiece introduces a life-saving feature: no-phone messaging and SOS alerts using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, plus an optional advanced microLED screen in a limited edition. It is the brand's top model and engineered to be the only gadget required to venture almost any location and monitor 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 version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the price of the standard Fenix 8.

You do receive a significant functionality for your investment, with industry-leading workout, movement and adventure monitoring. Its full offline mapping of the globe can automatically guide you back to the path if you lose your way absent a phone, and appear great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the smaller 43mm version found in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the display always active, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service plan rather than depending on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-enabled products, emergency messaging is not included for no cost.

Instead, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack position sharing – so your contacts or loved ones can monitor you while out jogging, cycling or comparable activities – along with emergency orbital SOS alerts.

Location updates and messages via orbital are then billed on top, with more expensive subscriptions offering various allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have completed setup, you just venture the door without your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, send texts and overall stay connected with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally via 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 mobile number is enough to register for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can use to expedite communication. Voice messages and calls perform OK, though as with the majority of wearables, you’re not going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest function. You can set it up to automatically send a URL to chosen contacts every time you start an exercise, so they can track your live position on a map. It’s excellent for monitoring competition performance, but it primarily acts as a utility for someone you trust to be aware of your location in case an incident occurs. It has typically worked effectively, though the actual position has sometimes lagged when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance shows 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 crucial lifeline, though it is important to remember that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered via the support site. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled materials. Garmin offers recycling programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re without coverage.

Outcome is an increasingly impressive 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 middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is very freeing to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the features. At least it isn’t dependent on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, cycling or hiking, but still wants to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED display, monitors all activities with premier GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: extremely expensive, LTE and orbital features need ongoing subscription, limited Garmin Pay bank compatibility, voice capabilities are sluggish, basic wearable functionality compared with competing watches.
