A method of updating embedded universal integrated circuit cards (eUICCs) on wireless communication devices. The method comprises reviewing transactions associated with eUICCs on wireless communication devices by each of a plurality of mobile network operators (MNOs), based at least in part on reviewing the transactions by the MNOs, assigning each of the MNOs to one of a first tier, a second tier, and a third tier, receiving a eUICC transaction by an eUICC updating application executing on a computer from an MNO, determining by the eUICC updating application a tier the MNO is assigned to, and sending the eUICC transaction by the eUICC updating application to a wireless communication device subject to restrictions associated with the tier to which the MNO is assigned, whereby eUICC updating transactions of MNOs are restricted based on MNO tier assignments.
