6.2.6 Notes
To activate the External SIM switch with this command, you must select a single
voltage (i.e. 3v only or 1v8 only) with the Wavecom feature command (AT+WFM).
This voltage will be used by the electrical SIM interface of the Wireless CPU ® . The
selection with AT+WFM must be the current settings (i.e. the reset flag must be
equal to 0)
