Message delivery in cellular roaming scenarios involves a user device activated with a home telecommunications service provider (TSP) that provides cellular service to the user device. The user device is located in a remote location and the user device is activated with a remote TSP providing roaming cellular service to the user device in a remote location on a cellular network of the remote TSP. A process includes, based on the user initiating a transaction with a remote application server that requires user authentication based on delivery of a transactional text message, receiving from the remote application server the transactional text message, encrypting the transactional text message to produce an encrypted transactional text message, and forwarding the encrypted transactional text message to the remote TSP for delivery as a short message service (SMS) text to the user device in the remote location via the cellular network of the remote TSP.
