:) No, that won't work. Not every APN gives you access to the
Internet, some users may use APNs that give them access to private
networks managed by the operators. I've worked with such a case in the
past.

I'd rather just fall back to DHCP for IPv4 instead of adding that ping
(Huawei-only?). I tried to test the issue with my Huawei QMI modem but
unfortunately it seems to be broken (doesn't detect the SIM properly);
Dan also said that he would check that with his modems.
