Depends where you live. I’m in Australia and phone companies aren’t allowed to activate a number without tying it to an ID. So criminals just use stolen IDs and regular people don’t get privacy. Also YMMV but virtually every service that needs phone verification won’t accept VoIP numbers anymore
Tutamail is the only service I know of that still doesn’t need anything but I don’t expect it to last. Email providers that don’t make you verify anything end up being used for spam and then websites just start blocking their domain from being used for account creation
It’s also absurdly lacking in features compared to Android/iOS (never mind app support) and the dev team is so small they can barely maintain existing device support. VoLTE is still unsupported in the majority of devices. The OS doesn’t even have basic security features like drive encryption
I like UBPorts a lot but I think the alternative/FOSS smartphone market is too fragmented between it and SailfishOS/PostMarketOS that none of them will emerge with enough adoption to be real competitors to the iOS/Android duopoly. Didn’t mean to be overly negative. Just my two cents
Gone back to paying for nearly everything in cash (good for budgeting I find too, can’t make impulse purchases if I only have enough money to buy what I came to the shops for). I also got a couple more friends to switch to Signal and make some other privacy-related changes. Slowly getting there
