>"All wireless phones, even those that are not subscribed to or supported by a specific carrier, can call 911. However, calls to 911 on phones without active service do not deliver the caller’s location to the 911 call center, and the call center cannot call these phones back to find out the caller’s location or the nature of the emergency. If disconnected, the 911 center has no way to call back the caller."
