Is it better ,or just as good to use a VoIP provider like https://voip.ms/ rather than mysudo for things like pseudonyms.For example,having a number dedicated for Shopping so that amazon doesnt have your phone number.The reason I ask this is because MySudo doesnt work on a degoogled phone like CalyxOS regardless if it has microG or not.Would apreciate any answers.
I have been in personal contact with the operator and they are indeed good as far as I can tell.
