There is a bug in 4.4.2 . To see fr yrself do the foll settings. Have a screen lock. Now after unlocking the screen lock go SIM manager & select the option " always ask". Now try making a call frm call logs or contacts. U should see a screen asking you to select bet Sim1 & Sim 2. However sim 1 & sim 2 buttons dont appear. Hence u cannot make any calls . The only way is to copy the number & paste on keypad screen. Wow ! Wat a way to use a smart phone..
