400电话使用之前是必须要进行首次充值一定话费的，没有预存款的400电话是接不到电话的。在您首次充值之后，我们会给您一个400电话管理平台，然后您就可以绑定号码，接听使用了。
It is necessary to charge a certain fee for the first time before using 400 telephones. 400 telephones without advance deposit can not be answered. After your first recharge, we will give you a 400 phone management platform, and then you can bind the number to receive and use it.

Therefore, the audit of 400 telephone calls is very strict, not all enterprises can handle it. Only regular, confident companies that use our 400 telephones and then achieve the desired sales objectives can handle 400 telephones.
