The capacitor placed on the Sim Vcc must not exceed 470nF.
2.9.3 SIM 3/5V management
The WISMO Quik Q24x6 Series module is designed to interface with 3V SIMs
only
2
.
Nevertheless, it is possible to manage 3V and 5V SIMs using an external level
shifter (see application notes in appendix). In this case, depending on the type
of SIM detected, the module firmware triggers the GPO0 output signal (pin
#26) in order to properly set the external SIM driver level (3V or 5V).

Most of the GSM operators have been providing 3V SIMs since 1998.
