What is the difference between PDP Context ID and APN Class?

IoT Modules MC/EM Series

Hi akn,
The PDP context ID is the ID of the PDP context that is defined on the device.

APN is the access point name, the APN identifies the packet data network(PDN) that a mobile data user wants to communicate with. We can call it is the gateway between mobile network and internet.
The APN is provided by network operator

For Verizon, the apn could be:

  • vzwims : Used for connections to IMS services. Required for TXT messaging.
  • vzwadmin : Used for administrative functions.
  • vzwinternet : Required for general Internet connections.
  • vzwapp : Required for PDA data service
  • vzwcf : Used for connections that must be routed through content filtering.
  • xx.vzwentp : Used for connections to mobile private networks.
    Note ‘xx’ would be replaced by the enterprise MPN identifier.
  • xx.vzwstatic : Used for static IP connections.
    Note ‘xx’ would be replaced by an appropriate static IP pool identifier.

Thanks,
