<div>As far as I know it depends upon the network settings enforcing if unciphered calls or data transfers are allowed or not. </div>

<div>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. </div>
