Can I check the previous phone number and restore the SMS content after canceling and redeeming it?

Cancellation and renewal of mobile phone number can not query the previous and restored SMS content.

Take Unicom users as an example. If the mobile phone card has been cancelled, there is no record of sending and receiving SMS (that is, SMS list).

After the mobile phone number is stopped, if the mobile phone fee is forgotten to be renewed or the long-term arrears reach a certain date, the mobile phone number will generally be cancelled.

However, there is also a time limit for getting the number back after cancellation. Because when dialing the mobile phone number after handling the number stop service, it also prompts that the number is empty.
