An SMS provider you can trust. Textbelt has worked with thousands of developers and businesses since 2012. Delivery statuses are not standardized between mobile carriers. For example, some carriers will report SMS as "delivered" when they attempt transmission to the handset while other carriers actually report delivery receipts from the handsets. Textbelt lets you receive replies after you've sent an SMS. Replies are sent by webhook, meaning you will have to set up an HTTP or HTTPS route on your website that will process inbound SMS.
