Is there a notification fee for Tencent's mobile phone recharge service?

This is a system service. If you recharge, you need to pay, and you don't need to remind.

Step 1: Enter Tencent to recharge, and click Charge Q coins /Q points. Step 2: Find the mobile phone in "self-recharge", select the mobile phone bill for recharging Q coins, and you will see the QQ number that needs to be recharged. Enter the QQ number, the mobile phone's location, and the number of recharges. After entering the verification characters, click Recharge Now to open the page. Your mobile phone will receive a text message asking you to reply to a certain number. After sending it, Tencent will send you a text message to tell you that it has been recharged, and you will be fine.
