I find the description of the EIT bit (allow multiple APNs, IPv4 and/or IPv6) a tempting feature. Can the EIT bit be set by using open-source software tools? For example, when I connect a linux computer to a 4G network I use ModemManager and mmcli open source software, on a cheap USB 4G key. Or is the EIT bit proprietary to one operator and smartphone manufacturer?
