Going to the business hall to apply for a text message can't be opened.

Hello, first of all, thank you for your support to China Telecom. According to your description, it may be that your package is not compatible with the business you handle. You can call 10000 for manual service and ask the staff to open it for you. You can also log in to the online business hall for self-service.

If you need to check the bill and pay the phone bill, please go to the online business hall of Anhui Telecom. Wish you a happy life!

I hope my answer will help you and be adopted by you!
