initial bearer apn

[Juan A. Rubio]

Hi,

I'm using ModemManager version 1.18.12. I'm also using Network Manager 1.22.16

I'm wondering what part of the system stores or configures the initial
bearer apn, since I'm not explicitly setting this value?

$ mmcli -m 0 | grep 'bearer apn'
           |      initial bearer apn: Telstra.internet

Is this a default value set by MM or NM, or is this something that is
stored in the SIM by the carrier?

Thanks,
Juan
