What's the matter with Unicom card automatically sending short messages to 100 10 every day?

Your situation is usually caused by downloading traffic monitoring software and sending instructions to correct traffic information at regular intervals. If not, I suggest you uninstall the software and cancel the sending of the correction instruction information. If you don't set the above information, it doesn't rule out that the function of automatically sending SMS to query traffic is turned on in the "sim card application" in the mobile phone. I suggest you try to turn it off. If you have any questions about this, I suggest that you can also contact the customer service of your place of origin.
