Abstract
A method including determining whether a subscriber identification profile (SIDP) is stored within a UE; sending an initial attach request along with a default network access key to a MME, upon determining that the SIDP is not stored; receiving a first authorization to attach to the network in response to the initial attach request, the first authorization restricts connectivity of the UE to an M2M activation system accessed by a dedicated APN associated with the default network access key; receiving, from a subscription management system, a SIDP generated by the M2M activation system; detaching from the M2M activation system and the network; sending a second attach request to the network based on the received SIDP; and receiving a second authorization to the network in response to the second attach request; the second authorization provides unrestricted APN connectivity and access to services associated with the subscriber identification profile.
