  1. eSIM: An embedded SIM (eSIM) is a small chip soldered onto a device's circuit board, which can be remotely provisioned and managed.
  2. SM-DP+: A Subscription Management Data Platform Plus (SM-DP+) is a server-side component that securely stores and manages eSIM profiles.
  3. LWM2M: Lightweight Machine-to-Machine (LWM2M) is a protocol used for device management, including eSIM provisioning and management.
