Cingular Wireless introduced a Push To Talk (PTT) service that is available on a pay-per-use basis. Customers using one of several wireless phones can now use the company’s PTT service, as needed, for $.15 per minute. Unique icons on the phone indicate whether other PTT customers are available before making a PTT call. The service also supports the ability to a convert a PTT call to a regular wireless voice call. Calls with up to 30 participants can be converted, creating a mobile conference call. Customers can also send a voice message to one person or a whole group.
Cingular launched its first PTT service over a year ago on a contractual basis. Since launching service, AT&T’s wireless unit has sold more than two million PTT capable phones.
