User manual

Verify GPRS Status: This button sends a command to the attached device to verify if it is registered on

the GPRS network. The possible responses to the command are the same as that for verifying the GSM

status. GPRS connectivity is required for data transmission.

Verify GPRS Activation: This button sends a command to the attached device requesting its network

assigned IP Address. If the device returns “000.000.000.000” then GPRS activation has failed.

Get PDP Rejection Cause: This button sends a command to the attached device to determine the cause

for PDP (Packet Data Protocol) rejection. If the attached device has reported connectivity failure as a

result of the previous button(s) the response to this command can help to determine the issue. The

possible responses to this command are:

• no PDP reject cause

• insufficient resources

• missing or unknown APN

• unknown PDP address or PDP type

• user authentication failed

• activation rejected by GGSN

• activation rejected, unspecified
