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

The latest iteration of Garmin's top-tier Fenix adventure watch introduces a life-saving capability: no-phone communication and emergency alerts using 4G LTE or orbital connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a limited edition. It is the brand's premier model and engineered to be the only gadget required to explore almost any location and track every activity.

This positions it as an extremely expensive proposition, priced from £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 edition with microLED display – nearly double the price of the standard Fenix 8.

Users receive a lot of features for your investment, with industry-leading workout, activity and outdoor tracking. Its full offline maps of the world can seamlessly guide you back to the trail if you get lost absent a phone, and appear great on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed does have an additional day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. However in contrast to competing satellite-enabled devices, SOS communication is not included for no cost.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE text and audio messaging, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while engaged in running, biking or comparable pursuits – along with SOS satellite SOS alerts.

Location updates and texts via satellite are then charged on top, with higher-tier plans including various quotas of orbital usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the service.

After you have completed setup, you simply venture outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, dispatch texts and overall stay connected with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is enough 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 set of customisable canned replies you can use to expedite communication. Voice messages and calls perform acceptably, although as with the majority of smartwatches, you’re not going to want to use it for extended conversations as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can configure to automatically send a URL to chosen contacts every time you begin an exercise, so they can track your real time location on a map. It’s great for following competition progress, but it primarily acts as a utility for someone you trust to know your location in case an incident occurs. It has typically worked well, although the actual position has sometimes lagged when transitioning in and out of strong LTE signal.

These capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is important to remember that orbital coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with services offered via the support portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without signal.

The result is an even more impressive outdoor device for those that desire to be unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

This is very liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to provide the features. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but nevertheless wants to be locatable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors everything with best-in-class GPS, integrated torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: very costly, LTE and satellite functions require ongoing payment, restricted Garmin Pay financial support, speech capabilities are slow, limited wearable features compared with Apple/Google/Samsung watches.
