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

This newest version of Garmin's flagship Fenix adventure timepiece brings a potentially lifesaving feature: no-phone communication and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an available advanced microLED display in a limited edition. This is Garmin's top device and designed to be the single gadget required to explore virtually anywhere and track every activity.

That positions it as an extremely expensive option, 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 – nearly double the price of the standard Fenix 8.

You do receive a significant features for your investment, with best-in-class fitness, activity and adventure tracking. The complete offline maps of the globe can automatically direct you back to the path if you get lost absent a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm size available in other devices, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life despite the screen always active, lasting a solid eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your phone provider, like other wearables. However in contrast to Apple or Google's satellite-capable devices, SOS communication is not provided for free.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, call functionality and LiveTrack position sharing – so your contacts or loved ones can keep an eye on you while engaged in running, cycling or comparable pursuits – along with emergency satellite SOS alerts.

Location updates and texts via orbital are then billed additionally, with higher-tier subscriptions offering different allowances of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can evaluate the service.

After you have completed setup, you just venture outside without your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, but you can place and receive calls, send texts and generally keep in touch with your family 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 install the Garmin Messenger application, you can then communicate back and forth using text or voice communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a mobile number is enough to register for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of customisable canned replies you can send to expedite communication. Spoken messages and calls work acceptably, although as with the majority of wearables, you’re not going to wish to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to selected contacts whenever you begin an activity, so they can track your real time location on a map. It’s excellent for monitoring competition performance, but it mostly acts as a utility for someone you trust to be aware of your whereabouts in case something happens. It has typically worked well, although the actual position has occasionally lagged when moving in and out of strong LTE coverage.

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

A guide displays you how to locate the clear view to the orbital system, which then sends and receives communications 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 most of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with options available via the support portal. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides disposal schemes 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re without signal.

Outcome is an even more impressive adventure 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 does so without requiring additional gear.

It is very freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the colossal price of the watch and the monthly fee of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone provider so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, cycling or trekking, but still wants to be locatable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED display, tracks all activities with premier GPS, integrated torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and orbital functions need ongoing subscription, limited Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable features versus Apple/Google/Samsung watches.
