• No network found.
A network is not currently available. The modem continues searching for a network.
• Packet data not available.
The current network does not support a packet data service.
• Packet data not allowed.
The modem is not allowed to use the packet data service on the current network (e.g. no
GPRS roaming agreement between network; a roaming agreement for voice may still be
in place). It is also possible that you do not have a subscription for GPRS at all.
The remaining error states are permanent:
• SIM is missing.
The SIM card is missing. After the SIM has been inserted a warm boot may be required.
• SIM failure.
