Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Texting

This latest iteration of Garmin's premium Fenix outdoor watch brings a life-saving capability: phone-free communication and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an optional state-of-the-art microLED screen in a special edition. This is Garmin's top model and designed to be the only tool needed to explore virtually any location and track all your movements.

That makes it 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 twice the price of the standard Fenix 8.

You do get a significant features for your money, with best-in-class workout, movement and adventure tracking. The complete offline mapping of the world can automatically direct you back to the path if you get lost without a phone, and appear excellent on the sizable, sharp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm version found in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as tested does have an additional day of smartwatch battery life despite the display always active, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service instead of relying on a watch plan linked to your phone carrier, like other wearables. But unlike Apple or Google's satellite-capable products, emergency communication is not provided for free.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in jogging, cycling or similar pursuits – along with SOS orbital SOS alerts.

Location updates and texts over satellite are then billed on top, with higher-tier subscriptions including various quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, send texts and generally stay connected with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary 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 typed or voice messages, and make 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.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It has a set of personalizable pre-set responses you can use to expedite communication. Voice messages and calls work OK, although as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a link to chosen contacts every time you begin an exercise, so they can track your real time location on a map. It’s excellent for monitoring race performance, but it primarily serves as a utility for someone you rely on to know your location in case something happens. It has generally worked well, though the actual location has sometimes lagged when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide displays you how to find the clear view 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 crucial lifeline, however it is important to note that satellite service is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options available via the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled materials. Garmin provides recycling programs on new purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service 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 standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re without signal.

The result is an increasingly remarkable adventure device for those that want to be unplugged. If you wish to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite freeing to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the features. At least it isn’t dependent on your phone provider so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, biking or hiking, but still wants to be locatable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, phone and standalone commands, 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.

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