After the electronic invoice is issued, it cannot be sent to the customer through WeChat. What happened?

1. Take China Mobile as an example, open the China Mobile APP, enter the China Mobile Function Panel, and select "My" from the five function options at the bottom of the homepage to enter my homepage.

2. In the drop-down panel of my page, find the function options of my assistant, find the function of electronic invoice in my assistant, and click the electronic invoice.

It can be sent by communication software such as WeChat and Q, or by email.

If the electronic invoice is not a pdf file, there is no electronic invoice service provider. The role of electronic invoice service providers is to format invoice characters and provide services such as anti-counterfeiting signature, storage and circulation.

If the electronic invoice issued is a pdf file, it means that some electronic invoice service providers usually ask customers to submit their mobile phone numbers or email addresses during the process of issuing invoices, and then send the invoices directly to customers' SMS or email addresses after the electronic invoices are successfully issued.
