I'm getting an error: "sslv3 alert handshake failure"

We don't support SSLv3 due to a security vulnerability:

You can force SSLv2 by using the --sslv2 flag with curl on most systems.

You can also just POST to, as opposed to https://. This will solve the problem, but traffic will not be encrypted (you might be ok with this for hobby projects because SMS is not secure to begin with).

Can I use Textbelt via Tor?

No, because of too much spam/abuse coming through Tor.

Can I use Textbelt with Postman?

Why isn't my VOIP number receiving SMS?

Unfortunately, Textbelt does not support sending SMS to VOIP numbers.
