Allentown residents using all of the nation's major wireless carriers can now text information to 9-1-1 operators.

Back in April, Allentown became one of less than 100 emergency 9-1-1 centers in the country to provide Verizon wireless customers the option of texting information when a person was unable to call 9-1-1.

T-Mobile customers were added in June, and according to city officials, service for Text to 9-1-1 was completed with the addition of AT&T and Sprint customers in July.

The Allentown 9-1-1 Center will now work with the other wireless carriers operating in the area to provide the potentially life-saving service to their customers by the end of 2014.

Text to 911 is intended primarily for use in two emergency scenarios:

* For an individual who is speech or hearing impaired or
* For a person who is unable to make a voice call, for example during a medical emergency that renders the person incapable of speech, or in the instance of a home invasion, domestic violence, or abduction.

Customers should use the texting option only when calling 911 is NOT an option. Users should call if they can and text if they can't.
