There are several reasons why the invoice cannot be obtained:

Invoice prompt amount is insufficient.

1. Only the amount recharged through Unicom's official channels can be invoiced through Unicom's channels; If the amount is recharged on third-party platforms (Taobao, WeChat, Alipay, etc.). ), you need to obtain invoices through third-party channels;

2. The authorized amount cannot be included in the invoiceable amount.

It cannot be displayed before 8: 00 on the 3rd of each month, and the invoice of last month cannot be printed. It is recommended to print invoices after the billing period.

The charging page and system are busy, which leads to charging failure. It is recommended to try charging later or change to another channel.
