Secure/not-secure is not a binary distinction. And SMS-based 2fa is still more secure than password alone.
One thing I've become painfully aware of recently is how all MFA is rendered pretty insecure by various "fallback" processes. I recently switch jobs and realized I had a few accounts using my old work phone as SMS 2fa number. In every case it was ridiculously easy to call a CSR and get 2fa disabled from their end.
