If the location cellular is suitable with it, and if the device tries to response to the writing, he will not reply to the unique variety, but to the specified one.
- Most providers don't examine this aspect of the concept, which indicates one can create whatever he wants in this area : a unique variety like 911, or the variety of somebody else. In a excellent execution of this function, the device would see the unique contact variety and the reply-to one.
