iMessage to HTC One mini

[JohnLT13]

My son recently switched from the iPhone 4s to the HTC One mini. He just swapped out sims (GSM AT&T) every time I(or anyone on iPhone) send him a text from my iPhone 5 it sends as iMessage. How do we fix this. TIA

He needs to disassociate his telephone number from his iMessage account and shut off iMessage on his iPhone 4s.

Both have been done previously. Still sends as iMessage.

Any other iOS devices or Mac computers signed into his iMessage account?

Talked to Apple on friday. They pointed me to the same links as FrancoisC. Going to AT&T tomorrow to and get a new sim. Also picking up my 5s 32gig Slate.
Thanks for the help people.
