Using Google Messages, those on Android will be able to text 911 using Rich Communication Services. This will let you see read receipts and typing indicators from emergency responders, thus eliminating the “uncertainty of waiting to see if your messages went through.”
Compared to SMS, RCS will allow you to send pictures and videos. Google says high-resolution media could “aid a faster and more effective response from emergency service providers.”
The last benefit is the ability to “share your precise location and additional information automatically through Android Emergency Location Service.” This can include your “language settings and opt-in Medical Information, so emergency responders know exactly where to go and can get helpful details from you even if you’re unable to reply.”
