Private Communication Systems
As an alternative to the a.m. procedure, since november 1997 an internet solution is
offered to the LSO. It is a password protected internet homepage where you can
enter the IMEI number of the affected handset. The page will then present Master
Phone Codes, Master Network Codes and Master Service Provider Codes (if
applicable to the relevant telephone).
If you do not have access to this tool up to now, please contact your Siemens
service manager for details.
