1

The destination requested by the Mobile Station cannot be reached because, although the number is in a valid format, it is not currently assigned (allocated).

8

The MS has tried to send a mobile originating short message when the MS’s network operator or service provider has forbidden such transactions.

10

The outgoing call barred service applies to the short message service for the called destination.

17

The MSC cannot service an MS-generated request because of PLMN failures, e.g., problems in MAP.

21

The equipment does not wish to accept this short message, although it could have accepted it since the equipment is neither busy nor incompatible.

27

The destination indicated by the Mobile Station cannot be reached because the interface to the destination is not functioning correctly. This indicates a signaling message was unable to be delivered to the remote user, e.g., a physical layer or data link layer failure at the remote user, user equipment offline, etc.

28

The subscriber is not registered in the PLMN (i.e., IMSI not known).

29

The facility requested by the Mobile Station is not supported by the PLMN.

30

The subscriber is not registered in the HLR (i.e., IMSI or directory number is not allocated to a subscriber).

38

The network is not functioning correctly and the condition is likely to last a relatively long period; immediately reattempting the short message transfer is unlikely to be successful.

41

The network is not functioning correctly but the condition is not likely to last long; the Mobile Station may try another transfer attempt almost immediately.

42

The short message service cannot be serviced because of high traffic.

47

Resources unavailable when no other cause applies.

50

The requested short message service could not be provided by the network because the user has not completed the necessary administrative arrangements.

69

The network is unable to provide the requested short message service.

81

The equipment has received a message with a short message reference not currently in use on the MS-network interface.

95

An invalid message event when no other cause in the invalid message class applies.

96

A mandatory information element is missing and/or has a content error (the two cases are indistinguishable).

97

A message type is not recognized either because it is not defined or is not implemented by the equipment.

98

Message not compatible with short message protocol state.

99

The message includes information elements not recognized because the element identifier is not defined or not implemented by the equipment.

111

A protocol error event when no other cause applies.

127

Interworking with a network that does not provide causes for actions it takes; thus, the precise cause cannot be ascertained.
