I have a Samsung galaxy A42 and I need the call waiting function to work. If I am already on another call it does not notify me that there is another call, it just diverts them to my voicemail box. I have looked in the call settings and call waiting is enabled… I am at a loss, please help. Call forwarding is active when busy FYI, but it should tell me I have a call waiting and then after a while go to voicemail if I do not take the call. My husband has the same contract as I do, just a G7 thinq and it works just fine… Any help appreciated, thanks.
