Deregistering my phone number.

If I deregister my phone number from apple servers while using my Android phone, can It be registered again once I go back to my iPhone? For the moment I'm using my Android but at some point later I want to go back to using my iPhone and deregistering my iPhone with the sim card doesn't seem to be working so the only other option would be with the confirmation code but I want to go back to using my phone later on.
