QChat is a cellular/data 2-way Push-to-Talk (PTT) technology developed by Qualcomm and designed for 3G and next-generation networks.

In addition, QChat enables one-to-one (direct) and one-to-many (group) calls and communication including the ability to add participants ad-hoc to existing calls by any participant.[39] It is optimized for UMTS HSPA/HSPA+ and CDMA 2000 EV-DO Rev. A networks, can roam across networks, is compatible with 1xRTT, and interoperates with iDEN. The largest QChat customers include Sprint in the U.S., Nextel International (NII) across Latin America, and China Telecom.
