Abstract
This application describes managing configuration of a bootstrap electronic SIM (eSIM) for a wireless device. A bootstrap eSIM on an embedded universal integrated circuit card (eUICC) of the wireless device is configured as needed to provide cellular wireless access. The bootstrap eSIM is configured with an initial international mobile subscriber identity (i-IMSI) value used to establish a cellular connection to obtain a bootstrap IMSI (b-IMSI) value allocated for temporary, dedicated use by the wireless device. The b-IMSI value is selected by a bootstrap server based on a bootstrap selection rule obtained from a bootstrap rules service, where the bootstrap selection rule accounts for a use case type provided by the wireless device and indicating a purpose for use of the b-IMSI value. The b-IMSI value is returned to a pool for use by other wireless devices after expiration of a timer or responsive to a delete notification message.
