I've got a second sim card in my phone. On an incoming call, there is no sound whatsoever, I only receive a sms notifying me about a missed call received and I must phone 132. When phoning 132, the voice mail tells me that I don't have any calls. Does this perhaps happen only to numbers that is not on my Contacts, or with blocked numbers? When I make the call to a blocked number, text appears that reads, conditional call forwarding. Is it possible that I've got my Settings wrong?
