Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Texting

The latest model of the premium Fenix outdoor timepiece includes a potentially lifesaving feature: no-phone communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating new cellular technology, along with an optional state-of-the-art microLED screen in a limited edition. This is the brand's top device and engineered to be the only gadget needed to explore virtually anywhere and track every activity.

That makes it an extremely 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 regular Fenix 8.

You do get a significant features for your investment, with best-in-class workout, movement and outdoor tracking. The complete offline maps of the globe can seamlessly direct you return to the trail if you lose your way absent a phone, and look great on the sizable, sharp and super-bright display.

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

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your mobile provider, like other smartwatches. However in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for free.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while out running, biking or comparable activities – plus emergency orbital SOS messaging.

Check-ins and texts over satellite are then billed on top, with more expensive plans offering various allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the functionality.

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 activities, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally using typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a mobile number is enough to register for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable pre-set responses you can use to expedite communication. Voice recordings and calls perform acceptably, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own 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 following race progress, but it primarily acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally functioned effectively, although the real location has occasionally been delayed when moving in and out of strong LTE coverage.

These capabilities are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to remember that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe excluding regions 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 initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal schemes on new purchases.

Cost

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

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re without signal.

Outcome is an even more impressive outdoor tool for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is very liberating to be outside without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the service. Fortunately it is not dependent on your phone carrier so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless wants to be locatable and contactable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, tracks everything with premier GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: very costly, LTE and orbital features require monthly payment, limited Garmin Pay bank support, speech capabilities are sluggish, limited wearable features versus Apple/Google/Samsung watches.
