Archived:SMS Messaging Client API in S60 1st Edition SDK broken (Known Issue)
SMS messages cannot be sent because required headings are missing from the S60 1st Edition SDK.
Etelbgsm.h header is missing from the SDK. Necessary settings such as SMS center for an SMS message is dependent on the Etelbgsm.h header.
It is possible to work around the issue by copying the header from the Nokia 9200 Communicator Series SDK and include it in the S60 SDK.
