and is there a firmware upgrade for the modem available (not the device but the modem within the device)?

Where can I download the old firmware V1.00(ABKQ.0)C0 ?

Same problem with my 'new' (bought an unused unit from a person) LTE3302-M432. Why Zyxel does not disclose the reason for this 'SIM card not ready' problem as this seems to be quite common issue in this modem and in LTE3301? This modem seems completely unusable - tried a few different SIM cards that work in other devices…
