How to create a data call or send an SMS in text or PDU mode (and how to check the PIN

the response is READY, no password is required. If the response is SIM PIN, the Nokia 30 is
waiting for a PIN code. It is possible that more than one password is needed. The following
example indicates how the PIN code is given to the Nokia 30.
