Abstract: A method for performing a telecommunication service, including identifying, on a Service Delivery Platform (SDP) and by a processor, the telecommunication service, selecting, on the SDP and by the processor, the telecommunication service, and executing, on the SDP and by the processor, the telecommunication service on a cellular network, where the SDP is configured to implement the telecommunication service on the cellular network.

Abstract: A method for performing a telecommunication service includes: obtaining, in a first message from a mobile device and by a processor, a first phone number to whitelist, where the mobile device is registered with a call screening service, and where the first message is a text message; storing the first phone number in a whitelist, where the whitelist comprises a plurality of phone numbers allowed to contact the mobile device; determining that the mobile device is roaming; activating, by the processor and in response to determining that the mobile device is roaming, the whitelist; receiving, after activating the whitelist, a second message for the mobile device from a second phone number; searching, by the processor, the whitelist for the second phone number to generate a failed search; and discarding, by the processor, the second message based on the failed search.

Abstract: A system for performing a telecommunication service, including a cellular network, a processor connected to a memory, a Service Delivery Platform (SDP), and the telecommunication service executed by the processor and configured to execute instructions for the SDP on the cellular network.
