How do telecom government and enterprise users cancel the monthly traffic package?

Hello, first of all, thank you for your support to China Telecom. According to your description:

Send 4 123 to 1000 1 as shown below to cancel your customized telecom traffic packet service.

If you need to buy a machine, please go to Anhui Telecom Tianyi Store to buy hundreds of mobile phones such as iphone, Samsung and Xiaomi at a low price.

I hope my answer can be adopted by you.
