SM Failure Cause: Missing or unknown APN
1. If the cause is Missing or unknown APN(0x1b), it indicates that the APN configuration is incorrect or APN resolving fails. In this case, check whether the "DNS QUERY REQ" message is available in the traced information.

2. It is also possible that the GGSN returns an APN error. That is, the "Create pdp Context Response" message sent from the GGSN to the SGSN carries cause 219 "Missing or unknown APN." In this case, configure the GGSN to allow
the access from the APN
