i am facing a problem with my 6600,here it is, When i send sms'es to some nokia phones(6600 , 3230 ) they are able to receive my text and read as normal but many handsets dont read my text and instead it says " message content cannot be displayed". I went to my provider airtel and he could not figure it out.
The message setting are normal.

Urgent help buddies.
