This disclosure describes procedures for maintaining multiple electronic subscriber identity modules (eSIMs) within a user equipment (UE) device, in such a manner that an inactive eSIM can be maintained/updated at the UE device while an active eSIM is being utilized by the UE device to communicate with a corresponding network. The procedures include, a UE device establishing communications with a first network using an active eSIM, initiating an eSIM manager at the UE device, selecting an inactive eSIM (e.g., associated with a second network) with the eSIM manager, applying a profile update to the inactive eSIM with the eSIM manager during communications with the first network, and deselecting the inactive eSIM with the eSIM manager when the profile update to the inactive eSIM is complete. In some configurations, the eSIM manager and the multiple eSIMs can be stored within a secure element of the UE device.
