Thank you!

Excellent plugin with full country support

By sultan456 on August 20, 2025

This plugin is excellent and supports all countries. The best part is that I was able to set Saudi Arabia as the default number, so customers don’t have to change the country manually. It saved me time and made the customer experience much smoother. Highly recommended!
