Reliable for SMS and OTP testing, console takes getting used to

|Twilio

As a QA I mostly use Twilio when testing SMS and OTP flows in the apps we build. The message logs in the console are the best part for me. I can see straight away whether an OTP was sent, delivered or failed, and the error codes usually point to the cause, like an unverified or badly formatted number. The test credentials are also handy for checking a flow without sending real messages every time.
