This creatable/settable object configures the Packet Data Protocol (PDP) type, such as IPv4 or IPv6, for a given data profile entry in the GSM PDP profile table. An admin sets this when defining a new data profile to match what the carrier's APN expects, since a mismatched PDP type can prevent the profile's data session from establishing at all. For example, migrating a profile to a dual-stack APN would require the admin to update this object to the appropriate combined PDP type the carrier now supports.
