Thank you for using China Telecom.
Please call the staff at 10000, and the staff will check how long your contract is based on your account information. I can't find it. It is possible that the contract period is up.
You can also bring your ID card to the business hall for enquiry.
Anhui Telecom will serve you wholeheartedly, and I hope my answer can be adopted by you.
If you have any questions, please consult the staff of Anhui Telecom's online business hall. Anhui Telecom recently held the brand mobile phone discount season for the 5th anniversary of Tianyi. Welcome to the business hall.
