How can I open a permanent yellow diamond?

First prepare a mobile card, and then open the QQ service you want to open (with SMS opening methods such as membership and yellow diamond). Everyone knows that QQ service will be charged after 72 hours. Just use this, wait for about 70 hours, and then cancel.

Then, stop your phone and restart it. Then restart (otherwise you can't log in to GPRS). At this point, the cancelled business will be reopened. This repeat can be successfully opened for free.

In addition, the service modes are: 55 rpm 1700, yellow diamond qh 170035, red diamond 130 rpm 10665999, green diamond ADA rpm 10665999, and basket diamond QQY.
