@NightBall06, did you ever use your simcard in an Apple device?

Apple has this annoying feature that if you ever even once send or receive sms with an iPhone device it will register that number as an isms contact in Apple network and every sms after that from any iPhone will not be sent via sms but via isms and that is apple-only messaging...

It's like they truly believe that once someone tries an iPhone they will never use any other device again...
