i posted this a couple of days ago, thought it redundant to post the same detail here… i think it will have the details you were looking for (aka i already read the manuals 3 days ago 😛 )  
[Help with 4G card - can’t get any modem to show up - uConsole - clockworkpi](https://forum.clockworkpi.com/t/help-with-4g-card-cant-get-any-modem-to-show-up/11276/5)

I even edited the enable script to restart the ModemManager service as that is needed EVERY time and not documented…

Even a simple connect is not working - so its either the APN details are wrong or they are only allowing iOS and Android devices like you say.
