What is the APN type?

While accessing a data network from a device with a SIM card. There can be different requirements for a data connection.  An APN type specifies the purpose of a data connection using an APN. For example, there may be a separate APN for MMS only.

APN Types

APN type is the parameter in settings.  Each APN represents a serving gateway. If an operator uses the same APN for all types of connection. Then APN type will be a wild card. Here we will describe various APN types.

MMS Apn Type :

This type of APN represents the service gateway for MMS communication. When a SIM card tries to send and Multimedia message, the MMS type of APN is select if there is any.  For an MMS there will be additional parameters required to configure in the settings e.g MMSC, Proxy or Ports, etc.

SUPL Apn Type:

The SUPL means for secure user plane location.   SUPL location type APN set up a secure connection with the location server in the operator’s network. Most of the time the default APN also serves the server for location.

Default Apn Type:

As the name implies, this is the APN which is used for the al data connection for all types of requirements unless another type of APN is not set up explicitly. A mobile operator may have multiple APNs configured in HLR for a subscriber, out of which one is the default.

DUN Apn Type:

DUN is for Dial-Up Networking connections for the internet.  The dialup is the older method for an internet connection. So this APN type is not used.

FOTA Apn Type:

Firmware Over the Air or FOTA is the gateway for setting up a data connection for the firmware updates. The default pan is used for Firmware updates too. But some times there is a need for a separate connection for firmware updates only.
