AT+CCED=0,x Causes Wismo to reset

Hi all,
I am using a Q2501B Firmware 651. I want to get Cell information to support the GPS (AGPS). However when I use the +CCED command for anything other than automatic updates my module resets. ie AT+CCED=0,1 or AT+CCED=0,2

The command works fine if the application is not running (any application appears to give the same problem)

Is there a way to resolve this problem?
