Parameter <old password> can be ignored if no old password was allocated to the facility.
Take into account that a password may have already been set by factory, or that the service is subject to a pass-
word issued by the provider. See notes above or contact provider.
New password. Mandatory, if <old password> was an unblocking key (such as the Master Phone Code).
