When I send an SMS message through Twilio, does the recipient of my SMS message get charged?
Twilio will only charge your Twilio Account for sending SMS messages through our API. We will not charge the recipient of your SMS message for receiving a Twilio SMS message. However, we cannot guarantee that the recipient of Twilio’s SMS message will not be charged by their phone provider.
Different mobile plans have different agreements for SMS messaging. Some mobile plans may charge the recipient to receive SMS messages. This depends on the mobile plan your recipients are using.
Twilio does not offer premium SMS messaging where the cost of receiving a SMS message can be passed on to the sender.
