Systems and methods for transmitting AT commands indicating whether Evolved Packet System (EPS) Session Management (ESM) information should be transmitted securely are disclosed herein. A Terminal Equipment (TE) may transmit an AT command to a Mobile Termination (MT). The AT command may indicate whether protocol configuration options (PCO) should be ciphered and/or whether an access point name (APN) is provided. In some embodiments, the AT command may be a dedicated command and may only include a parameter and an parameter. Alternatively, or in addition, the AT command may include a parameter, an parameter, and/or additional parameters serving additional functions. Whether the APN is provided may be determined based on whether the parameter is present and includes a non-null value. The AT command may be related to a single packet data network (PDN) connection or may relate to a plurality of PDN connections.
