The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Messaging

This newest iteration of the premium Fenix adventure watch brings a life-saving feature: phone-free communication and emergency messaging via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an optional advanced microLED display in a limited edition. This is the brand's premier device and designed to be the single gadget required to explore almost anywhere and track every activity.

That positions it as an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to 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 get a lot of features for your money, with industry-leading fitness, movement and adventure tracking. The complete offline maps of the world can automatically direct you back to the path if you lose your way without a phone, and look excellent on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your mobile carrier, as with other smartwatches. But unlike competing satellite-capable products, SOS messaging is not provided for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE SMS and voice messaging, calls and LiveTrack location sharing – so your contacts or family can monitor you while engaged in jogging, biking or similar pursuits – along with SOS orbital SOS alerts.

Check-ins and texts over satellite are then charged additionally, with more expensive plans including various allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, 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 sends them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally via text or voice communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a mobile number is enough to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable canned responses you can use to speed things up. Voice messages and calls perform acceptably, although as with most smartwatches, you’re not going to wish to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the most useful function. You can configure to automatically transmit a URL to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s excellent for monitoring race progress, but it mostly serves as a utility for someone you trust to know your whereabouts in case something happens. It has generally functioned effectively, although the actual location has occasionally been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, however it is important to remember that satellite service is restricted to the US continent, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with options available through the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling schemes on new purchases.

Cost

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 cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, location update and emergency SOS for when you’re without signal.

The result is an increasingly remarkable adventure tool for those that want to be unplugged. If you wish to have someone monitor you from afar while exercising out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

This is very liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to enable the service. At least it isn’t dependent on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still wants to be locatable and contactable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED display, tracks everything with premier 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.

Drawbacks: extremely expensive, LTE and orbital features need ongoing payment, limited Garmin Pay financial compatibility, voice capabilities are sluggish, limited wearable functionality versus competing watches.
