This review draws on manufacturer specifications and published field testing.
The Garmin inReach Messenger Plus is a pocket-sized satellite communicator for places with no cell service. It sends and receives texts over satellite, can trigger an SOS to Garmin’s 24/7 emergency response team and, unlike earlier inReach devices, can send photos and short voice messages. It lists at $499.99 and requires a Garmin satellite subscription.
Quick Verdict
The Messenger Plus is one of the best ways to stay in touch from remote areas, and its SOS feature has a proven track record. It’s a communication device first: navigation is basic, and it works best paired with your phone.
- Good: Texts up to 1,600 characters, photo and voice messages, reliable 24/7 SOS, long battery life, small and light, can charge your phone
- Not so good: About twice the price of the original Messenger, subscription required, tiny screen, basic navigation, relies heavily on a paired phone

What Stands Out
Messages finally feel like real messages. Earlier inReach devices limited texts to 160 characters. The Plus allows up to 1,600, and adding a photo of the campsite or a short voice note makes it much easier to tell family what’s going on.
SOS you can count on. Pressing SOS connects you with a staffed emergency response center that can coordinate rescue and message back and forth with you. Field reviewers report it working in a real rescue.
The battery lasts for weeks. In normal use, Treeline Review got about 20 days between charges, and it can also top up your phone in a pinch.
Where It Falls Short
The small monochrome screen is fine for reading messages but slow for typing, and the buttons are hard to use with gloves. There are no on-device maps, and TracBack shows waypoints rather than a full breadcrumb trail, so it doesn’t replace a GPS or navigation app. Most of the experience happens through the Garmin Messenger app on your phone, which means a lost or broken phone limits what you can do. In one extreme-cold test, the unit shut down several times around 4°F. Finally, the subscription is an ongoing cost; check Garmin’s current service plans, since photo and voice messaging depend on your plan.
Who Should Buy the inReach Messenger Plus?
It’s a good choice for backpackers, hunters, anglers heading to remote lakes, overlanders and anyone whose family wants to hear from them while they’re out of cell range. If you only need SOS and short check-ins, the cheaper original Messenger or a newer phone with built-in satellite texting may be enough.

Final Thoughts
The inReach Messenger Plus makes satellite communication feel much closer to normal texting, while keeping the SOS reliability Garmin is known for. Factor in the subscription, carry a separate navigation tool, and it’s an excellent safety net for time off the grid.
