Mobile devices are provisionally registered when the mobile device does not have an active subscription profile. A communications session is established with an access network of a mobile communications network. Identification data for the computing device is sent to the access network. A connectivity configuration is used to allow the computing device to establish a limited connection on the mobile communications network. Using the limited connection, an eSIM profile is received. The eSIM profile is activated and the device is connected to an associated mobile network.
