Is there a way to only use iMessage/Facetime with my iCloud account?

This may be a noob-ish question... But is there a way to disable my phone number entirely and use iMessage/Facetime ONLY with my iCloud account? i know i know, go to the settings and manipulate the addresses... But when there is a SIM card installed it still checks the phone number and grays it out so you can't uncheck it...

Why do I want to do this you ask? I'm currently deployed to Kuwait... and I have two phones with two different SIM cards/phone numbers. Sometimes when i go to iMessage someone it will default to the phone number. Rather than confuse everyone back home I wanted to disable the phone number entirely and just message strictly through the iCloud account. Similar to how you would do on a non-cellular device (iPad, etc.)

Is there any way to do this or is it always going to have the phone number checked by default.

You cannot disassociate your phone number because it is needed for SMS/MMS purposes. You can however, change the "Send & Receive" a option in the message settings to your Apple ID.
