Q: If the message is not received, will there be a failed reply or feedback?
A: When sending short messages using API interface, the interface call error code can display the status of the task of sending short messages. There is no deduction for sending failure.
Q: Is there a time limit for sending short messages?
A: Delivery time is unlimited, usually up to 3-5 seconds.
Q: Can the sender's number show the same number?
A: We won't support it. Intelligent scheduling function is currently used, which guarantees that the optimal channel is used for each transmission, so the access number will change.
