China Telecom sent 100 short messages an hour, but the short message function was locked, so it was impossible to send short messages, and other functions were normal. Are there any similar problems?

Are there any similar problems? ask Hello, first of all, I suggest you call customer service 10000 to ask about the situation. Sending a large number of short messages in a short time may cause congestion in the short message center. If you send messages to one person continuously, you may be locked. If this is the first time, you can find customer service to unlock it, and you can't unlock it the second time. thank you
