Troubleshooting
I'm getting an error: "sslv3 alert handshake failure"
We don't support SSLv3 due to a security vulnerability: disablessl3.com.
You can force SSLv2 by using the --sslv2 flag with curl on most systems.
You can also just POST to http://textbelt.com/text, 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?
Yes. Here's a screenshot of a Postman configuration that works:
Why isn't my VOIP number receiving SMS?
Unfortunately, Textbelt does not support sending SMS to VOIP numbers.
