Error States
5.12.4.2 Error States
The following temporary error states (i.e., these states may disappear without
interaction) 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.
• GPRS not available
The current network does not support GPRS.
• GPRS not allowed
The modem is not allowed to use GPRS 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 sub-
scription 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.
