Not after the electronic invoice is generated.

According to the information you provided, if you can't issue electronic invoices by yourself through online channels, the following situations may exist:

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, so you cannot 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 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.

The above situation remains unresolved. It is recommended to contact the Unicom customer service to which the number belongs.
