Love my A52 5g, but it diverts to voice mail in 15 seconds. Usually by the time I hear it, and get it out of my pocket. I tried the you tube sequence which worked on my S8 fine, but doesn't work on A52? I contacted Samsung help who gave me the same codes, tried again, but no luck. They then told me to contact Vodafone, my network. Just spent 90 minutes on chat service, turning voice mail off , on again,off on. Trying **61*121*25#call many times, again and again, but just the same. Any other ideas please?!? Thanks
