Access Point Name
The logical name that is used to select the GGSN or the external packet data network. If the value is null or
omitted, then the subscription value will be requested.
Packet Data Protocol address
Identifies the MT in the address space applicable to PDP (e.g. IP V4 address for PDP type IP). If the value is
null or omitted, then a value may be provided by the TE during the PDP startup procedure or, failing that, a
dynamic address will be requested. The read command will continue to return the null string even if an address
has been allocated during the PDP startup procedure. The allocated address may be read using AT+CGPADDR.

Controls the PDP data compression (applicable for Subnetwork Dependent Convergence Protocol (SNDCP)
only) 3GPP TS 44.065
[0] off
Header Compression
Controls the PDP header compression 3GPP TS 44.065, 3GPP TS 25.323
