Can be used normally. You can call and answer the phone to receive SMS online, but you can't send SMS.

According to the information you provided, if your number can't send short messages, other services can be used normally, and there are no settings or hardware problems in your mobile phone and mobile phone card. It doesn't rule out that your number is blacklisted by short messages. If you are blacklisted by short messages from the public security department, you need to contact the local public security department to cancel the short message blacklist. If you are blacklisted by our company because of too many short messages, you can delete the short message blacklist in your own business hall. For details, please contact the local Unicom manual customer service consultation. The actual situation is subject to local policies.
