How to recharge the SMS?

Mobile SMS recharge needs to be bound to the user's bank card, and you can bring your ID card and bank card to the business hall to open it. Now many business halls can enjoy the first recharge 100 delivery 15, triggering the preferential activities of recharging 15.

After the bank card is successfully bound, you can directly send CZ to 10086 to recharge it if you want to recharge it in the future (it seems that sending SMS to recharge and sending phone bills now are also superimposed).
