Addition of secondary endpoint based on message reply

A network device, comprising:

• an interface configured to communicate with a network;
• a memory configured to store instructions;
• and
• a processor, coupled to the interface and the memory, wherein the processor is configured to execute the instructions stored in the memory to:
• receive a request to add a second UE as an additional endpoint for a service associated with a first UE, wherein, when receiving the request to add the second UE, the processor is further configured to execute the instruction to receive a push notification ID and a network identifier of the first UE,
• generate a transaction identifier in response to receiving the request,
• send a command to provide a short message service (SMS) message to the first UE requesting permission to add the second UE as the additional endpoint,
• receive a message granting permission to add the second UE as the additional endpoint, wherein the message includes the network identifier assigned to the first UE,
• generate at least one credential for authorizing the second UE to access the service, and
• provide the at least one credential to the second UE.

A method, comprising:

• receiving a request to add a second user equipment (UE) as an additional endpoint for a service associated with a first UE, wherein the received request includes a push notification identifier and a network identifier of the first UE;
• generating a personal identification number (PIN) in response to receiving the request;
• sending, to the second UE, a code identifying an entitlement server and the PIN;
• receiving the PIN and a phone number of the first UE from a short messaging service center (SMSc);
• generating at least one credential for authorizing the second UE to access the service;
• and
• providing the phone number of the first UE and the at least one credential to the second UE.
