0 Not registered, ME is currently not searching for new operator
There is a technical problem. User intervention is required. Yet, emergency
calls can be made if any network is available. Probable causes:
• no SIM card available
• no PIN entered
• no valid Home PLMN entry found on the SIM
1 Registered to home network
2 Not registered, but ME is currently searching for a new operator
ME searches for an available network. Failure to log in until after more than a
minute may be due to one of the following reasons:
• No network available or insufficient Rx level.
• ME has no access rights to the networks available.
• Networks from the SIM list of allowed networks are around, but login fails
due to one of the following reasons:
- #11 ... PLMN not allowed
- #12 ... Location area not allowed
- #13 ... Roaming not allowed in this location area
After this, the search will be resumed (if automatic network search is
enabled).
• The Home PLMN or an allowed PLMN is available, but login is rejected by
the cell (reasons: Access Class or LAC).
If at least one network is available, emergency calls can be made.
3 Registration denied
• If automatic network search is enabled:
Authentication or registration fails after Location Update Reject due to one
of the following reasons:
- #2 ... IMSI unknown at HLR
- #3 ... Illegal MS
- #6 ... Illegal ME
Either the SIM or the ME are unable to log into any network. User interven-
tion is required. Emergency calls can be made, if any network is available.
• Only if manual network search is enabled:
Manual registration fails after Location Update Reject due to the following
reasons:
- #2 ... IMSI unknown at HLR
- #3 ... Illegal MS
- #6 ... Illegal ME
- #11 ... PLMN not allowed
- #12 ... Location area not allowed
- #13 ... Roaming not allowed in this location area
No further attempt is made to search or log into a network. Emergency calls
can be made if any network is available.
4 Unknown (not used)
5 Registered, roaming
ME is registered at a foreign network (national or international network)
