Can't Hongdu Telecom send short messages?

Hello, first of all, thank you for your support to China Telecom. According to your description, if the SMS is received normally but cannot be sent, please follow the following steps to resume business:

1. First, check whether a large number of short messages have been sent in a short time. According to the requirement of the Ministry of Industry and Information Technology to punish spam messages, China Telecom has set a threshold for users to send messages every hour and every day. If messages are sent in excess, they will join the blacklist system. At this time, you need to call the customer service hotline 10000 to cancel the blacklist.

2. Please check whether the mobile terminal has set a limit on the number of short messages sent.

3. Check whether the "timing information" is set on the mobile phone, which leads to the delay in sending the short message and mistakenly thinks that it has not been sent successfully.

4. Please use other telecom mobile phones to test whether it is a terminal problem or a mobile phone UIM card problem. For terminal problems, you can try to save important information and restore factory settings. For UIM problems, you can change your card in the nearest business hall.

5. If you don't have the conditions to change the machine, please go to the nearest business hall and have it tested by the telecom staff.
