- providing a group of wireless devices, each wireless device having internally stored account parameters associated with a prepaid amount of authorization for usage of the wireless device;
determining a need for a required change in at least one internally stored account parameter associated with the prepaid amount of authorization for usage in the select group of wireless devices;
obtaining an encryption key uniquely associated with the group of wireless devices;
generating an encrypted account update message using the encryption key and the selected at least one account parameter to be changed;
broadcasting the encrypted account update message for receipt by the group of wireless devices in order to update the internally stored account parameters within the group of wireless devices to replenish their internally stored prepaid amount of authorization for usage, wherein the broadcast encrypted account update message is only able to be received and decrypted by those wireless devices within the group of wireless devices.

Abstract
A system and method are provided for the broadcast replenishment of account parameters for select groups of wireless devices, where select groups of wireless devices have their internally-stored account parameters (e.g., prepaid amount of usage authorization) simultaneously updated as a group by a single broadcast message, such as an encrypted SMS message. An account update message is generated based on the account parameters to be updated and encrypted using an encryption key uniquely associated with the select group of wireless devices. The encrypted account update message is broadcast for receipt by the select group of wireless devices, such only those wireless devices previously provided with a key for decryption can receive and decrypt the broadcast account update message. The wireless devices use information and/or instructions in the broadcast message in order to update their internally stored account parameters accordingly.
