Can you still find the content of the previous text message after more than one month of redemption of your mobile phone number?

The main question is, after the cancellation of the mobile phone number for more than one month, can I use this number again to query the previous SMS content? You can't. Because after cancellation, this number does not exist. When the number becomes empty, all the information on the previous number, including SMS and contacts, will be deleted. If you cancel it, you can still check the records, which is too unsafe for people who use this number in the future. Because of the cancelled number, China Mobile, China Unicom or telecom companies will reactivate this number after a certain period of time, because the number resources are limited. So I can't find the content of the previous message.
