How to reply to SMS for free?

Hello, first of all, thank you for your support to China Telecom. There is a charge for direct reply by SMS. You can log in to your email, and replying to emails is completely free.

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!
