Unfortunately, CommsMobile does not allow changing a data plan to a mobile plan.
Activating a CommsMobile Service
However, if you are interested in activating a CommsMobile service, you may do so by ordering a new SIM card through the website or app, or by getting one from a participating store.
Setting up the CommsMobile Service
Once you have the new SIM, simply log in to your CommsMobile account and follow the set-up instructions to activate your new CommsMobile service.
