Hi,

I've just bought Zyxel LTE7490-M904 device, but it doesn't recognise any SIM card I tried placing in - two different operators from Bosnia, UK EE, Telekom from Serbia. I saw some other posts on "special" firmware that makes various SIM cards detectible. Anyone knows anything about this issue?

Kind regards!
