Ideally I'd like one without sim-swap vulnerability. I recall Google Fi being considered one option meeting that criteria, primarily because they lack human customer service reps and thus can't be social engineered into porting numbers to new sims [1].

Is that still the case? Are there any others that do security and privacy well, that HN'ers are happy with?
