1. A system for automatically re-provisioning embedded universal integrated circuit cards (eUICCs),
wherein each embedded universal integrated circuit card (eUICC) is associated with a eUICC manufacturer (EUM) and is provisioned with a respective initial mobile network operator (MNO) profile that is associated with a respective initial MNO,
wherein the initial MNO operates a first network that covers a first MNO geographic area, comprising:
at least one processor that executes program control instructions to:
maintain a database of MNO profiles associated with a plurality of MNOs; determine if a eUICC is located outside the first MNO geographic area; and
if the eUICC is located outside the first MNO geographic area, then emulate commands and/or functions that are used by the initial MNO to provision the initial MNO profile on the eUICC to replace the initial MNO profile on the eUICC with a second MNO profile that is associated with a second MNO that operates a second network that covers a geographic area where the eUICC is located;
wherein the initial and second MNO profiles on the eUICC configure a wireless device to communicate with the first and second networks, respectfully, wherein the commands and/or functions that are emulated include a subscription manager data stack (SM-DP) and/or a subscription manager secure routinq stack (SM-SR) that are used by the initial MNO to provision the initial MNO profile on the eUICC.
