About APN charges

You cannot apply for an APN instance in a general business office. You must apply for an application from the relevant data department, major account service department, or cluster department. Currently, the fees for APN instances are not subject to a unified standard. You can consult with your local carrier when applying. The carrier charges an APN fee, mainly because of the establishment of this domain and the maintenance cost of the domain. If you use a large number of APN cards, the carrier may create this domain for you for free, free of APN charges. If there are few cards, you will be charged for some monthly rental fees.

When enterprise users use wireless transmission, it is recommended to apply for an APN. After applying for an APN, users in the domain can only access each other and are completely isolated from the outside, providing high security.

Sometimes two SIM cards can access each other without an APN application. The reason is that when two cards log on to the ggsn using the same sgsn in the same place, the two SIM cards can access each other. This method can be used during testing.
