SMS.to partners with different carriers and network providers. These providers charge per submitted SMS message. All submitted messages from SMS.to platform to the local network providers were charged regardless of the status.
We have no interest or advantage if you get any FAILED messages, your loss is our loss and we ourselves get charged the same amount for FAILED and DELIVERED. If a phone number is recognized as invalid, we do not even submit it for delivery and the message will remain in status REJECTED without any charge for you.
