As far as I know it depends upon the network settings enforcing
if unciphered calls or data transfers are allowed or not.
I think few countries (including India) used to mandate the operators to
negotiate null ciphering algorithm that is no ciphering - I verified this
about 2 to 3 years back where my local network in bangalore was not turning
on ciphering, however I am not aware of the current status.

hi,
some stupid question: if a phone does not support any encryption, is it
possible to use it on an official GSM network? (authentication works, of
course) if so, what phone might it be?
