Methods, systems, and computer program products for offloading prepaid credit status queries from prepaid credit status databases for unlimited-plan prepaid in-network calls is provided. According to one aspect, the subject matter described herein includes a method that includes intercepting, at a signaling message routing node, a prepaid status query associated with a call originated by a calling subscriber and directed to a called subscriber. The signaling node then determines whether the calling subscriber is associated with an unlimited calling plan, unlimited text messaging plan, unlimited multimedia messaging plan, or a combination of plans based on the intercepted prepaid status query. The node also determines whether the call is an in-network call based on the intercepted prepaid status query, where an in-network call includes a call between a calling subscriber and a called subscriber belonging to the same network. In response to determining that the call is an in-network call associated with a calling party associated with an unlimited calling, text messaging, or multimedia messaging plan, the signaling node generates a prepaid status response instructing the query originator to connect the call. Alternatively, in response to determining that the call is not an in-network call associated with a calling party associated with an unlimited calling, text messaging, or multimedia messaging plan, the signaling node forwards the prepaid status query to the intended destination prepaid status database.
