Provisional device registration

A computing device comprising:

• a memory storing thereon instructions that when executed by a processor of the computing device, cause the computing device to perform operations comprising:
• establishing, by a core network of a mobile communications network, a communications session with a mobile communications network, wherein the computing device does not have an active subscription profile for accessing mobile communications services provided by a mobile network operator on the mobile communications network;
• sending, via the core network, identification data for the computing device;
• establishing a limited connection on the mobile communications network, wherein the limited connection is usable to receive data pertaining to subscriptions for accessing the mobile communications services, send data indicative of a subscription selection, and receive an embedded subscriber identity module (eSIM) profile;
• using the limited connection to receive the eSIM profile;
• and
• activating the eSIM profile and connecting to an associated mobile network, wherein the computing device obtains limited communications services from an alternative core network that is served by an access network.

A system configured to communicate with one or more devices via a mobile communications network, the system configured to:

• receive identification data for a device that does not have an active subscription profile for accessing a mobile communications network;
• send, to the device via a core network, a connectivity configuration that is operable to allow the device to establish a limited connection on the mobile communications network, wherein the limited connection is limited to receiving data pertaining to subscriptions for accessing the mobile communications network, sending data indicative of a subscription selection, and receiving an embedded subscriber identity module (eSIM) profile;
• and
• allow the device to use the limited connection to receive the data pertaining to subscription information and to select and receive an eSIM profile, wherein the device obtains limited communications services from an alternative core network that is served by an access network.
