Sometimes it has to be activated manually by the operator.<BR /><BR />If you can borrow a different&nbsp;SIM card, preferably&nbsp;from a different operator from a friend, colleague or family member that would be great, so we can see if this only occurs with your SIM card or your operator.<BR /><BR />Let me know how it goes!</P> Tue, 15 Jan 2019 08:33:41 GMT https://community.sony.lu/t5/l-series/the-call-waiting-function-is-not-activated/m-p/3624914#M6338 Jonas 2019-01-15T08:33:41Z
