The caveat to this “no monthly fee” setup is that you HAVE to have your smartphone in Bluetooth range of the watch, which is typically 30 feet, but it could be much less depending on your situation. The good news is that when you do step out of Bluetooth range and separate from your phone, the S3 vibrates and puts a message on the screen to let you know it is disconnected.
Although the S3 works the best with Samsung phones, as would be expected, Samsung’s website says it is compatible with many other Android phones running the operating system 4.4 or higher. However, the compatible phone list on the Samsung site indicates that the SOS feature may not work with a non-Samsung phone. Yet I have read other sites that say features like Samsung Pay now work with non-Samsung phones. So I am hopeful that the SOS feature will work as well.
We tried the S3 with a Samsung Galaxy Note 4 phone running Android 6.0, and it worked exactly as advertised! It called and texted everyone on the list. The call was clear and easy to understand. The GPS located Assistive at our exact Fargo address and when I tried it at another location it located us at the house next store. I think that is pretty good for a no fee GPS locator and emergency alert.
In the future, I would like to see more compatibility with non-Samsung phones and a larger dedicated SOS RED button with a one hold press requirement. Otherwise it is another nice “no monthly fee” option for some people.
