As documented a few days back, if you want/need a partial alternative to some of the services that Silent.link provides, do try jmp.chat, which does not rely on eSIM to get you a working US or Canada phone number.
For that same reason (no SIM), it doesn't give you data, obviously, and you need your own source (WiFi, mobile, etc). That's why I say it's a partial alternative only, depending on your use case.
