How to renew the contract by promising to send traffic?

1. At present, the policies and package types of different cities and regions are different, and the ways of renewing the contract for the promised traffic reduction activities are also different.

2. If 3G users of Henan Unicom send "CNDX" to 100 10, the automatic SMS reply can be graded. If the user prompts garbled code or something else after sending a short message, it means that the user cannot participate in the renewal; 4G users can renew their contracts by sending short messages CNHF to 100 10, their own business halls or other processing channels.

3. For more information, please contact Unicom's manual customer service for consultation. The actual situation is subject to local policies.
