Garmin Messenger App
The non-satellite messaging features of the Garmin Messenger™ app alone should not be relied on as a primary method to obtain emergency assistance. The Approach® S70 watch cannot initiate an SOS rescue.
The app works over the internet using a wireless connection or cellular data on your phone. If you are using cellular data, your paired phone must be equipped with a data plan and be in an area of network coverage where data is available.
You can use the app to message other Garmin Messenger app users, including friends and family without Garmin® devices. Anyone can download the app and connect their phone, allowing them to communicate with other app users over the internet (no login is required). App users can also create group messaging threads with other SMS phone numbers. New members added to the group message can download the app to see what others are saying.
Messages sent using a wireless connection or cellular data on your phone do not incur data charges. Standard text messaging rates for your cellular data plan apply.
You can download the Garmin Messenger app from the app store on your phone (garmin.com/messengerapp).
