LTE3302 SIM Card Not Ready

From a web search I realise this is a common issue, but the solution only seems to be by private messages from Zyxel?

I have a unit that is displaying the dreaded SIM card not ready message.
I have already done a factory reset, and also a firmware update… all result in the same message.

It is an EE SIM, which I have also configured manually for APN etc.

I also have a Vodafone SIM which gives the same issue.

Any one able to help with this?

    Is your LTE3302 able to detach the SIM card. Or it can't detach SIM card?
    If the machine is not able to detach the SIM card, you can put a tape in the back of the SIM card to increase the thickness of the SIM card.
    If it still not work, you might have to do the RMA.
