What is Push to talk in my Nokia phone?
Push to talk (PTT) is a direct method for one-on-one or one-to-group communications. The principle of the service is simple – by pushing just one button on your Nokia phone, one-way communication can be started to an individual or a talk group over GSM (GPRS) network. The connection is almost instantaneous. Push to talk requires network support and must be ordered. Each party must have a compatible mobile phone or device and have Push to talk service activated.
