T-Mobile introduced push-to-talk services in Hungary last month, the first commercial carrier to do so. The Waterworks of Budapest is the first corporation to contract for the service.

The service will be available on a daily and monthly basis on T-Mobile's GPRS/EDGE/3G network, and the carrier is offering several Nokia P2T handsets, including the 6170, 5140, 6020, 6021, 6230i, 3230, 6630 and 6680.
