Can I manually update the apn name?

It looks like there is an apn name stored in: /home/sixfab/.core/configs/config.yaml

Can I manually update that name, reboot, and change the apn name?

Hi,

Yes, it can be updated, but we do not recommend manually updating it to avoid any errors. This can be done through Sixfab Connect.

Thanks. Can I change it to any arbitrary name? It looks like I can only change it to sg1.super, de1.super, or super from a dropdown. I want to change it to something else for a different sim.

Since the Sixfab CORE is unable to support SIM cards other than the Sixfab SIM, it will not work with any APN other than the ones specified.
