Notes
• You can register, disable, enable and erase
4 and 5 as described above. However, querying the
status of
4 and 5 with
will result in an error ("+CME ERROR: operation not supported").
As an alternative, you may use the ATD command followed by *'# codes to check the status of these two rea-
sons. See
Star-Hash (*#) Network Commands
for a complete list of *# GSM codes.
• Most networks will not permit registration of new parameters for conditional call forwarding (reasons 1,2,3,5)
while unconditional call forwarding is enabled.
command offers a broad range of call forwarding options according to the GSM specifications.
However, when you attempt to set a call forwarding option which is not provisioned or not yet subscribed to,
the setting will not take effect regardless of the response returned. The responses in these cases vary with
the network (for example "OK", "Operation not allowed", "Operation not supported" etc.). To make sure check
the call forwarding status with
=2.
• Some networks may choose to have certain call forwarding condtions permanently enabled (e.g. forwarding
to a mailbox if the mobile is not reachable). In this case, erasure or deactivation of call forwarding for these
conditions will not be successful, even if the CCFC request is answered with response "OK".
• The command has been implemented with the full set of
parameters according to 3GPP TS 27.007
. For actual applicability of SS "call forwarding" to a specific service or service group (a specific
value) please consult table A.1 of 3GPP TS 22.004
• There is currently no release of 3GPP TS 22.004
, in which the "Call Forwarding" Supplementary Service
is defined as applicable to SMS services.
