1. A method comprising:
receiving, at a service, a device registration request sent by an endpoint device, wherein the endpoint device executes an onboarding agent that causes the endpoint device to send the device registration request via a cellular connection to a private APN (access point name) associated with the service;
verifying, by the service, that a network address of the endpoint device from which the device registration request was sent is associated with an integrated circuit card identifier (ICCID) or international mobile equipment identity (IMEI) indicated by the device registration request;
identifying, by the service, a tenant identifier associated with the ICCID or IMEI; and
sending, by the service and based on the tenant identifier, a device registration response to the endpoint device via the private APN, wherein the tenant identifier is used by the service to identify a target APN via which the endpoint device should communicate, and the device registration response is indicative of the target APN.
