Ask HN: Best Google Voice alternative to receive SMS? (My country not allowed)

There have been recent cases of sim hijacking in my country (theories about employees from the phone companies involved), and I use some important apps that still uses an outdated 2FA with SMS.

I tried to set up a Google Voice account (even paying), to receive a number where I could get SMS and set that number as my 2FA for those apps.

However, Google Voice is not allowed in my country. Is there any trustworthy alternative that I could use? I think Twilio may provide this service but not sure if I could get a nice dashboard for this (I do not want to code an API).

Just to clarify, my only requirement is to have a SMS number to receive 2FA codes from outdates apps that still use that (also, when travelling abroad would be easier because I wouldn't need roaming, only an internet connection)
