Occasionally a reply report will appear on my phone, saying that it was sent successfully, but I haven’t done anything at all, and I haven’t sent any text messages. Is my phone infected?

This is actually not a problem with the mobile phone or mobile phone card. It is because you have set up the information reporting function of text messages. This function is similar to the read receipt in email. After you send the text message, if the other party receives the text message, the operator will send you a report showing that the message has been sent. If the other party is turned off and has no signal at the time, the operator will send you a report when the phone is turned on and there is signal. Sometimes due to network problems, it may take a while for you to receive the report sent to you. Generally, the report will be sent back to you after the text message is sent, but sometimes it will take more than ten minutes to reply to you, and sometimes it will take several days. That's why the above situation occurs.

Of course, it is not ruled out that your mobile phone is poisoned. If you never send text messages but receive a reply, it must be poisoned. Please contact customer service immediately. These are viruses causing trouble, and they are very likely to suck you. money.
