Confidential / Released
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
The 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.
• The 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 MS or the ME are unable to log into any network. User
intervention 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
