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.
