Contacted Tech support and they remote controlled...checked settings and cleared cache and reset signal on my phone and my son's and still not receiving any. He receives mine.

Welcome to the forums. Have they checked his phone to ensure everything is correct?

Welcome to Android Central! Is your son sending messages from an iPhone or Android phone?
