Mobile money service, Zoompass, expected to launch in Canada, on June 15.

Canada's three biggest wireless carriers are set to jointly announce a new service that allows subscribers to use their mobile devices to send money back and forth as easily as they swap text messages – a tentative first step into the realm of mobile commerce.

Dubbed Zoompass, the PayPal-like service is set to be launched Monday by a company called EnStream, a joint venture involving Rogers Communications Inc., Bell Canada Inc. and Telus Corp.
