1 Your number is in an abnormal state such as arrears and blacklist. It needs to be restored to normal state before it can be issued;
2 You have already issued a paper invoice, and you can't issue an electronic invoice;
3 The invoiceable amount has been exceeded, and electronic invoices cannot be issued after the limit is exceeded. Please print the original paper invoice in your Unicom business hall.
4 For users who recharge through third-party channels (such as WeChat, Alipay, Yi Hao, air recharge, etc.), please consult a third party to receive the invoice.
5 The system is busy, so it is suggested to deal with it later.
The above situation is still unresolved. It is suggested to contact the Unicom customer service where the number belongs.
