How many days does it usually take to transfer a China Mobile card?

In view of the differences in business regulations among provinces, you can call local 10086 for specific information. Taking Henan Province as an example, you need to bring your ID card or certificate + service password/local SMS/association circle (at least one) for transfer. Both new and old owners need to go to the business hall to handle the process. Institutional customers need to present the company certificate with official seal and the original valid ID of the person in charge, and settle the phone bill for the month. It will take effect on the day of application. After the transfer is successful, the original owner will no longer be able to use it, and new customers will not be able to query any phone bill information or call records before the transfer.
