Shandong Weifang Unicom mobile phone card how to change the package (not real-name registration system, I don't know the ID number)?

To handle business, you need to provide the ID card or authentication information of the owner of real-name registration system, so you need to handle the transfer to handle business. If you don't know who the previous owner is or can't contact the previous owner, some cities can trust the original valid documents and provide the invoices for the last six consecutive months to the business hall for transfer. However, the commercial policies of different cities are different, depending on local conditions. It is suggested that you can consult Unicom customer service or go to the business hall to find out.
