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

The most recent model of Garmin's flagship Fenix adventure timepiece introduces a potentially lifesaving feature: no-phone communication and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating cutting-edge mobile tech, along with an optional state-of-the-art microLED screen in a special edition. It is the brand's top model and engineered to be the only gadget required to venture virtually anywhere and monitor every activity.

This positions it as an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the standard Fenix 8.

Users get a significant functionality for your investment, with best-in-class workout, activity and adventure monitoring. Its full offline maps of the world can seamlessly direct you back to the trail if you get lost absent a phone, and look great on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as tested does have an additional day of watch battery life even with the display on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service service instead of relying on a watch plan tied to your mobile carrier, like other wearables. But in contrast to Apple or Google's satellite-capable products, SOS communication is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messaging, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in running, cycling or similar activities – along with emergency satellite SOS messaging.

Location updates and texts over satellite are then billed additionally, with higher-tier plans offering various allowances of satellite usage, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the functionality.

After you have completed setup, you simply head out the door minus your phone and the watch will connect to LTE. You can not use it for playing music or similar activities, but you are able to make and take calls, send texts and overall keep in touch with your family and friends.

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

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable canned replies you can send to expedite communication. Spoken messages and calls perform OK, although as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically send a URL to selected contacts every time you begin an exercise, so they can follow your live location on a map. It’s excellent for monitoring race progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has generally worked well, although the actual position has sometimes lagged when transitioning in and out of good LTE signal.

These capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, however it is important to remember that orbital coverage is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with options offered through the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused materials. Garmin provides disposal programs on recent purchases.

Cost

This Fenix 8 Pro is priced 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

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive outdoor tool for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outside without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the service. At least it is not reliant on your phone provider so works with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but still desires to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and satellite functions require monthly payment, restricted Garmin Pay bank support, speech features are slow, limited wearable functionality versus competing watches.
