I like how easy it is for customers to send text messages via their phone numbers with just one click of button instead using SMS gateway or other third party providers who charge expensive service fees in addition to sending international texts that can be as high as $0.40 per message depending upon your plan provider.
It's always good if there are no issues faced by users so far but i have not come across any problems while solving my clients' needs yet. We do receive many emails from our customer support team regarding technical queries which helps us solve them immediately without waiting for long time periods when reaching out through social media platforms etc.
