repeated: Searching for network, Registered on network, Searching for packet data,
and Ready to connect.
Error States
The following temporary error states (i.e., these states may disappear without inter-
action) may be displayed:
• Emergency calls only.
The modem has found a network but is not allowed to register (e.g. no
roaming agreement between networks). The modem keeps searching for
another network.
• 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.
The SIM card is permanently disabled (e.g. because the wrong PUK has
been entered too many times). A new SIM is needed.
• Modem failure.
The modem did not respond to commands as expected. If a warm boot does
not clear this condition, the modem may need to be replaced.
• NDIS error.
An internal software error has occurred. If a warm boot does not clear this
condition, Psion Teklogix technical support may need to investigate further.
