The mobile phone number has expired for several months, and you can still receive text messages. What's going on here?

The mobile phone number will be fully restored six months after you turn it off. You can get the information six months ago. But it's usually spam. When the card is inserted into the mobile phone after half a year, the words "Mobile" or "Unicom" will not be displayed. What should be displayed is something like "SIM card error" or "SIM card invalid".
