Abstract: By providing and using a machine-to-machine (M2M) Embedded Universal Integrated Circuit Card (eUICC) in a consumer cellular telephone, a wireless carrier is able to download and manage profiles on the eUICC and is able to enable it for service on new networks, such as a wireless carrier's 5G or other network and migrate the cellular telephone to the new network without any interaction of the consumer with the cellular telephone and, in most cases, without any knowledge of the consumer that anything on their cellular telephone or SIM has changed. This is different from consumer style eUICCs where interaction of the consumer with the cellular telephone is needed.
