The present invention provides a system and method for providing Customized Applications for Mobile network Enhanced Logic (CAMEL) Subscription Information (CSI) of an outbound roamer of a Home Public Mobile Network (HPMN) such that the outbound roamer is roaming in a Visited Public Mobile Network (VPMN). The system comprises a roamers database storing an outbound roamer record of at least one outbound roamer, wherein the outbound roamer record comprises at least the International Mobile Subscriber Identity (IMSI) of the outbound roamer. The system further comprises a detection block to detect whether provisioning of the CSI is required for the outbound roamer and a CSI generation block to generate the CSI of the outbound roamer based on at least the IMSI of the outbound roamer, if the provisioning of the CSI is required. The system further comprises a provisioning block to provision the generated CSI of the outbound roamer to at least one CSI storing node.
