Abstract

Methods, devices, and servers for as-needed update of a trusted list are provided herein. An electronic subscriber identity module (eSIM) server receives a request for an eSIM of a particular type from a wireless device. The eSIM server evaluates the particular type and requests an eSIM of the particular type from a second eSIM server, which is not initially trusted by a secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device. The wireless device passes the policy update to the SE, for example, a universal integrated circuit card (UICC). The UICC updates the trusted list with an identity of the second eSIM server. When the wireless device downloads a bound profile package (BPP) containing an eSIM from the second eSIM server, the UICC validates the BPP based on the updated trusted list. The eSIM is then installed on the UICC.
