An eSIM management framework can serve as an abstraction layer between various partners, mobile network operators, mobile-virtual network operators, and/or enterprises and SIM or eSIM vendors. The eSIM management framework can facilitate real-time SIM and/or eSIM profile provisioning to reduce consumption of network resources. In some examples, an eSIM management framework can facilitate just-in-time client-side provisioning, which can include on-demand generation of an appropriate SIM or eSIM profile.
