Why can't China Telecom receive the short message from the communication assistant?

Hello, first of all, thank you for your support to China Telecom. According to your description, after you handle the communication assistant, the system will send you a short message to remind you when you turn it off or turn it on when the service area cannot be connected, or when you can use it normally. You can log on to the online business hall-Personal Center-to handle the business, and see if you have unsubscribed from this business. Please call 10000 for details.

China Telecom's 4G has been officially commercialized. If you need to inquire about 4G tariffs, check bills, pay phone bills and buy mobile phones, please visit the online business hall of Anhui Telecom. Wish you a happy life!

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