Why do I use Unicom card to open the green diamond, and there is no binding information?

Why is there no binding information when using Unicom card to open green diamond?

Unicom card operators don't support green diamond service temporarily, so they can't bind.

How to open the green diamond:

1. Open QQ wallet;

2. In my QQ service, click More Services, find the green diamond, and click Open at the back;

3. Select the opening month and the opening payment method, and click Start Payment to enter the payment. After the payment is successful, it can be processed.
