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

The newest model of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving capability: no-phone messaging and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available advanced microLED screen in a limited edition. This is the brand's top model and designed to be the single tool needed to venture virtually any location and track all your movements.

That positions it as an very 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 screen – nearly double the price of the regular Fenix 8.

You do get a significant features for your investment, with best-in-class fitness, movement and outdoor monitoring. Its complete offline maps of the globe can automatically direct you back to the path if you lose your way absent a phone, and look excellent on the sizable, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life despite the display always active, lasting a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital subscription plan instead of depending on a watch plan tied to your mobile carrier, as with other wearables. But unlike competing satellite-enabled products, SOS messaging is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE SMS and voice messaging, calls and LiveTrack position tracking – so your friends or loved ones can monitor you while out running, cycling or similar activities – plus SOS satellite SOS messaging.

Location updates and texts via orbital are then billed additionally, with higher-tier subscriptions including various quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a phone number is sufficient to register for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can use to speed things up. Voice messages and calls work acceptably, although as with the majority of smartwatches, you’re not going to want to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can set it up to on its own send a URL to selected contacts whenever you start an exercise, so they can track your real time position on a map. It’s great for following race performance, but it primarily acts as a utility for someone you trust to know your whereabouts in case something happens. It has typically worked well, although the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide displays you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that satellite coverage is limited to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with options available via the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin offers recycling schemes on recent purchases.

Price

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

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without requiring anything else.

It is very liberating to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to provide the features. Fortunately it isn’t dependent on your phone carrier so functions with all brand of smartphone and network.

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

Pros: LTE and satellite communication, super-bright OLED display, tracks everything with premier GPS, integrated flashlight, voice 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, physical controls and touch.

Cons: extremely costly, LTE and satellite functions need monthly subscription, restricted Garmin Pay bank support, voice features are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
