I’ve been using this plugin with Contact Form 7 on my WordPress site and it’s been great. The phone number verification works smoothly with OTP via SMS, WhatsApp, and even voice calls. Setup was super easy and it saves my sales team a lot of time since leads are already verified. I also like that it has a redirection option after form submission, which makes the workflow more flexible.
