An improved cellular network architecture enables the provisioning of mobile profiles on devices lacking bootstrap profiles. A mobile device transmits an attach request that includes a pre-configured mobile country code (MCC) and mobile network code (MNC) uniquely associated with an emergency data session. The mobile device is then null-authenticated with a subscriber database, and an emergency data session is established, the emergency data session allowing traffic to a mobile profile manager. The mobile device can then download a mobile profile from the mobile profile using the emergency data session. Thus, a mobile device does not require a provisioning profile to download a full (or provisioning) mobile profile from a cellular network as in existing solutions.
