You can change the SIM priority by using the Dual SIM wizard under the Wizards hyper link on the units Home page Webui and selecting what sim slot has priority over the other.
Another way to do this in the Webui is to go to Configuration-->Network-->Interfaces-->Advanced-->PPP 0-9-->PPP1-->Mobile.
Then select SIM to use.
