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

The latest model of Garmin's flagship Fenix adventure timepiece brings a potentially lifesaving capability: no-phone communication and emergency messaging via 4G LTE or orbital links.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's top device and designed to be the single gadget required to venture virtually anywhere and monitor all your movements.

This makes it an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

Users get a lot of features for your money, with industry-leading workout, movement and outdoor tracking. The complete offline maps of the globe can seamlessly guide you back to the path if you lose your way absent a phone, and appear excellent on the large, sharp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as tested does have an extra day of smartwatch battery life even with the screen on all the time, enduring a solid eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your mobile carrier, like other smartwatches. But unlike competing satellite-capable devices, emergency messaging is not provided for no cost.

Instead, plans begin from £7.99 or similar a month, which provides limitless LTE text and audio messages, calls and LiveTrack position tracking – so your contacts or family can keep an eye on you while engaged in running, cycling or similar activities – along with emergency satellite SOS alerts.

Location updates and messages via satellite are then billed additionally, with more expensive subscriptions including different quotas of orbital use, climbing to a £50 a month unlimited plan. 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 playing music or similar activities, but you are able to place and receive calls, send texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or spoken messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It has a set of customisable canned replies you can send to expedite communication. Spoken messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to wish to use it for extended discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to on its own transmit a link to chosen contacts whenever you start an exercise, so they can follow your live location on a map. It’s great for following race performance, but it primarily acts as a utility for someone you rely on to be aware of your location in case something happens. It has generally worked effectively, although the real position has occasionally been delayed when moving in and out of strong LTE coverage.

These features are available on other Garmin watches 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 send texts, position check-ins and SOS SOS.

A on-screen assistance 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 unexpectedly straightforward to use and could be a vital lifeline, however it is essential to note that orbital service is limited to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with services offered through the customer service portal. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused components. Garmin provides recycling schemes 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 packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of signal.

The result is an even more impressive adventure device for those that desire to be phone-free. 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 needing anything else.

This is quite liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to provide the features. At least it is not dependent on your phone provider so functions with all make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, cycling or hiking, but still wants to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and satellite communication, super-bright OLED screen, tracks everything with best-in-class GPS, built-in flashlight, phone 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 orbital functions require ongoing subscription, restricted Garmin Pay bank support, speech capabilities are sluggish, basic smartwatch functionality versus competing watches.
