I have a Cirrus GL-AP1300LTE with a EC25-AF modem, and I’m trying to set it up with a SIM card from Visible, the Verizon MVNO. I get a persistent message that says, “SIM card not registered”. I’ve tried automatic setup and manual setup. I also tried using the following modem commands that were mentioned on a thread at the LTEHacks forum.
AT+QPRTPARA=3 AT+QMBNCFG="AutoSel",0 AT+QMBNCFG="Deactivate" AT+CFUN=1,1 AT+QCFG="usbnet",2 AT+QCFG="nwscanmode",3,1 AT+CGDCONT=1,"IPV6","VSBLINTERNET"
The end result is always the same: “SIM card not registered” and no Internet connection. The SIM works fine in an iPhone, but IOS 14 currently has problems with tethering over USB. Does anyone know how I can get a Cirrus router to work with a Visible SIM? Thanks.
