The main difference I can think of is that LTE registration depends on a
default bearer.  You may have to configure an APN and context type for
this.  How to do that on a modem is not well defined unfortunately...
You could try configuring context ID #1. Use the APN and context type
that works on your phone.

But I guess ModemManager already should to this, so the problem is
probably something else...

Anyway, no harm in testing. Use a terminal program connected to the AT
command port:

 AT+CGDCONT=1,"IPV4V6","APN"

Or start ModemManager with --debug and run

 mmcli -m 0 --command='+CGDCONT=1,"IPV4V6","APN"'
