The SW version of my T610 is R1A081. Whenever I use the handset at the time of the call connecting I hear a loud "dong" noise and a message "ciphering switched off" appears on the screen long with a triangle with an exclamation mark.
When I used the same sim card on a T610 with software version R1L, this problem disappeared.
Can anyone tell me how I can switch this feature off
