Sources tell the Wall Street Journal that sales of BlackBerry‘s (BBRY) new Q10 smartphone are far below expectations.

The Q10 features a physical keyboard in addition to a touchscreen and was aimed at fans of the company’s traditional keyboard-equipped devices, which were once extremely popular among business and government professionals.

BlackBerry hasn’t released any official numbers regarding Q10 sales, but one wireless retail chain owner in the Midwestern U.S. says most Q10 phones were returned to BlackBerry after consumers expressed little or no interest in the device. Moreover, players in the used mobile phone market say they haven’t seen a surge of people selling older BlackBerry devices, something that usually follows a new product launch.

BlackBerry has seen its market share collapse due to competition from Apple‘s (AAPL) iPhone and smartphones running Google‘s (GOOG) Android operating system. The company had been pinning its hopes on the launch of its new BlackBerry 10 operating system, but its new Z10 flagship phone hasn’t attracted much consumer interest either.

Earlier this month, BlackBerry said it was exploring its options, including a possible sale of the company.

Shares of BlackBerry rose modestly in Thursday morning trading.
