As long as I remembered to deactivate iMessage on my phone and disassociate my phone number with iMessage on any other Apple devices, I wouldn't have problems getting subsequent SMS from other iPhone users. The problem only occurred for me when I forgot to do this before moving my SIM card.
It is a royal P.I.T.A. though and the predominant reason why I don't frequently switch back and forth between phones.
