Texting without an assigned phone number I have an iPhone 5C that is no longer connected to a service plan. I have given it to my son to use as an iPod-type device. I have an Android phone. Can he text me on my Android from the non-connected iPhone?
He should be able to text you and anyone else. He needs to be on wifi (only) and use a 3rd-party texting app (for messages to Android) or Messages to another Apple device. 

He will not be able to send any messages when not on wifi because he won't have any cell signal.
