Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Texting

The latest iteration of Garmin's top-tier Fenix adventure timepiece includes a potentially lifesaving capability: no-phone messaging and SOS messaging via 4G LTE or orbital links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new cellular tech, along with an available advanced microLED screen in a special edition. This is the brand's premier device and designed to be the single gadget required to venture almost anywhere and monitor every activity.

That makes it an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the price of the regular Fenix 8.

Users receive a lot of functionality for your investment, with industry-leading workout, activity and adventure tracking. The complete offline mapping of the world can automatically direct you return to the path if you get lost absent a phone, and appear excellent on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your mobile carrier, as with other wearables. However in contrast to Apple or Google's satellite-capable products, emergency communication is not provided for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messages, calls and LiveTrack position sharing – so your contacts or family can keep an eye on you while out jogging, biking or similar pursuits – plus emergency orbital SOS messaging.

Check-ins and texts over satellite are then charged on top, with higher-tier subscriptions including different quotas of satellite use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the service.

Once 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 streaming music or comparable activities, but you can place and receive calls, send texts and overall keep in touch with your family and friends.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or voice messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can use to speed things up. Voice recordings and calls work OK, although as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own transmit a link to chosen contacts whenever you start an exercise, so they can follow your live location on a map. It’s great for monitoring race progress, but it mostly serves as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically functioned effectively, although the real location has occasionally lagged when moving in and out of good LTE coverage.

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

A guide displays you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is important to note that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with services offered through the customer service site. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch lacks any reused components. Garmin offers disposal programs on recent purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor 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 outside without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach service to enable the service. Fortunately it isn’t reliant on your phone provider so works with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but still desires to be locatable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED screen, tracks everything with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and orbital features require monthly payment, limited Garmin Pay bank support, speech capabilities are slow, basic smartwatch functionality versus Apple/Google/Samsung watches.
