SIxfab SIM card working in NETGEAR M1 but not in 4G USB Modem


My 4G USB with SIxfab Simcards does not work when I went from Canada to California but my Netgear M1 seems to work fine. Both products were working fine in Canada. The 4G USBs have worked well in the US before.

Do you have any idea of settings or configurations I can do that would get it to work?

Settings are set to connect to any network. There are no monthly limits. APN is super.

Any ideas would be appreciated.
