Can I transfer the number of China Mobile with a letter of introduction?

In view of the different business regulations in different provinces, you can call local 10086 for details. Take the customers of Henan Mobile as an example. You need to bring your ID card or certificate+service password/local SMS/contact circle (at least one) when you transfer, and both new and old car owners must be present when you handle it. The company's customers need to use the official seal of the company certificate and the original valid certificate of the manager to settle the phone bill of the month. After the transfer is successful, the original owner will no longer be able to use it, and new customers will not be able to inquire about any phone bill information or call records before the transfer.
