Unable to send and receive calls in Galaxy Grand 2 after kitkat update Last week I updated my grand 2 to Kitkat 4.4.2 and now I am not able to send or receive any calls from my device when I dial any number it gives me the message "not registered on network", I have searched many solutions on internet but they are not helping me because after making 1 or 2 calls may device again stops making calls. If any one knows how to resolve this issue kindly help me, I am frustrated because of this issue as I am not able to do the basic tasks from my device.
when you say you "updated your phone" I'm not sure exactly what you're referring to. If you got an OTA (over-the-air) update from the settings menu in your phone (direct update from your mobile carrier), then you'll need to call the customer support for your carrier. They can usually reset your network settings remotely or walk you through troubleshooting the issue. If you updated it by rooting your phone and flashing a custom rom (you'll know if you did because it's a complex process that takes at least an hour) then you should try to flash a different rom. I've personally had problems with several roms not being able to place calls. Hope this helps!
