Why didn't Tik Tok give a hint when he shook the coin?

Because the SMS reminder function is off. After Tik Tok Extreme Edition turns on the recharge SMS reminder, there will be a recharge reminder function after recharging. As long as you recharge, there will be SMS reminders, and the amount is not limited. If you don't receive SMS reminder after recharging, it may be information delay, because sometimes the system will respond slowly, and it needs to be submitted for review after recharging, and the recharging can be successful only after the system has passed the review.
