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. 1. A method comprising: receiving, from a carrier server, a first request for an eSIM of a first type;', initiating an eSIM installation process with a device; and', sending, to a second eSIM server, a second request to reserve the eSIM on behalf of the device,', 'receiving, from the second eSIM server, a first identifier of the eSIM, and', 'sending, to the carrier server, the first identifier., 'when the first eSIM server does not host eSIMs of the first type], 'when the first eSIM server hosts eSIMs of the first type], 'by a first electronic subscriber identity module (eSIM) server2. The method of claim 1 , wherein the first eSIM server is a certificate authority (CA).3. The method of claim 1 , further comprising: receiving, from the carrier server, a bind command message, wherein the bind command confirms a pairing of the eSIM with a universal integrated circuit card (UICC), and wherein the UICC is present in the device; and', 'forwarding, to the second eSIM server, the bind command message., 'when the first eSIM server does not host eSIMs of the first type4. The method of claim 3 , wherein the ...
