Recently, I can't send short messages with telecom mobile phones, and the network is still good. I have been texting, but I haven't sent it for a few days, and I can't get it.

Hello, according to the description, if there is no problem with the customer service query system data, it should be an error in the background data. It may also be because you sent too many short messages in a short time, and the system decided to block the number of spam messages and turn off the short message function. You can only take your card to the local telecom business hall to find customer service. After the face-to-face demonstration, the customer service will contact the backstage staff to check the correct data before solving it.
