To activate a pre-provisioned mobile device on a network, an initial data communication for device activation is allowed between the device and an self-activation portal. At this point, the network prevents other more regular communication of the mobile device via the network. The portal automatically collects identification information from the mobile device and collects information from the user to activate the device on a network service account. The portal causes a provisioning system to provision data to network elements to activate device service in the network. After provisioning is complete, a notification is sent to the mobile device; and after device communication is completed a record that controlled routing to the portal before activation is deleted. The mobile device then communicates via the network to obtain data for storage in the device, to complete activation and permit normal operation of the mobile device via the network.
