I transferred my line to VZW about 3 weeks ago. Since transferring everytime I get a text message while on a phone call I get a call waiting tone. This only happens during a phone call. I get a normal message tone when recording a text message outside of a phone call. I have checked the settings (to include the message tone) and can't find any issue. I also had a Samsung rep check the settings at Best Buy as well. This started on a S10e and I have since switched to a S10+ as it has continued. Any suggestions to fix this problem?
