Garmin Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for No-Phone Texting

The latest model of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving capability: phone-free communication and SOS alerts via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge cellular technology, plus an optional advanced microLED display in a special edition. It is Garmin's top device and designed to be the single gadget required to explore almost any location and track all your movements.

That makes it an extremely expensive option, priced from £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 cost of the regular Fenix 8.

Users receive a lot of features for your investment, with industry-leading fitness, activity and adventure monitoring. Its full offline mapping of the world can automatically guide you return to the trail if you lose your way absent a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as tested does have an extra day of watch battery life even with the display always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital service service instead of depending on a watch plan linked to your mobile carrier, as with other smartwatches. However unlike competing satellite-enabled devices, emergency messaging is not provided for no cost.

Instead, subscriptions start at £7.99 or similar a month, which provides unlimited LTE SMS and voice messages, calls and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or comparable pursuits – plus SOS satellite SOS messaging.

Check-ins and texts over orbital are then billed on top, with more expensive subscriptions including different quotas of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, send texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, just a mobile number is enough to register for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned responses you can use to expedite communication. Spoken recordings and calls perform acceptably, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to chosen contacts whenever you start an activity, so they can track your real time location on a map. It’s great for following competition performance, but it primarily acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned well, though the actual position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to note that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services offered via the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin provides recycling programs on new purchases.

Price

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

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without signal.

The result is an increasingly impressive outdoor tool for those that want 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 anything else.

This is very liberating to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the features. At least it isn’t reliant on your phone provider so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still wants to be locatable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, tracks everything with premier GPS, integrated flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very costly, LTE and orbital functions require monthly subscription, limited Garmin Pay financial compatibility, voice features are slow, limited smartwatch features compared with Apple/Google/Samsung watches.
