Once the inReach SOS is activated the control center texts you to find out if you activated the SOS and need to be rescued. You then have the opportunity, if you are able to reply, to let them know what the problem may be. If you do not reply they send out a rescue. Having the ability to communicate your circumstances has many many benefits.

Here is one example of the benefit of being able to communicate with your rescuers.....There are many many more examples of such rescues.
