I don't need to pay for the time being. There seems to be a few dollars in it. But the problem is that this calling card has been bound with several service packages, and it will be charged at the beginning of the month. That little money is simply not enough. Many people suddenly owe money within a few days of school. If you want to use this calling card, I suggest you call or send a text message to 10086, choose a package according to your own needs, and pay more phone bills to avoid sudden arrears at the beginning of the month. If you don't want to use this, just buy one at school after school.
