What did China Unicom Huimin Card experience for free in the first month?

When Unicom Huimin Card is activated, you can enjoy 3GB of domestic traffic in the current month +5 domestic short messages (plus 5 in the next month)+free domestic voice communication between users of the same package+free domestic answering+caller ID;

Tips: For the first time, you can recharge your phone bill in 50 yuan and give away your phone bill in 50 yuan. There is a short message to remind you when giving away, and the content of the short message is "Your recharge subsidy has been received in 50 yuan, thank you for using it". If the user's first recharge is less than 50 yuan, and the accumulated recharge reaches 50 yuan on the same day, he can't enjoy the discount.
