What do you mean by three-five-digit mobile phone cards?

Virtual card refers to the operators who have no basic network, buy mobile communication services from telecom, China Mobile and China Unicom, repackage them into their own brands and sell them to end users.

The number on the back of the SIM card of a mobile phone is the electronic serial number of the SIM card, also known as the IMSI number. The electronic serial number of each SIM card is unique and is directly assigned to the corresponding operator by ITU.

When the user opens the mobile phone card service, the corresponding phone number and electronic serial number will be automatically bound to the operator's switch, so that the mobile phone SIM card can be used normally.
