Reviving an old thread. A lot of useful information, thank you.
I am trying something similar, trying to add EC25-AF as a secondary modem to LTaP LTE6. Cannot get the PPP interface working, nor can I change it to an LTE interface.
More details below:
[admin@MikroTik] > port print
Flags: I - inactive
# DEVICE NAME CHANNELS USED-BY BAUD-RATE
0 serial0 1 Serial Console auto
1 gps 1 115200
2 1-2 usb3 1 PPP <ppp-out1> auto
[admin@MikroTik] >
And, I can see the modem:
[admin@MikroTik] > system resource usb print
# DEVICE VENDOR NAME SPEED
0 1-0 Linux 3.3.5 xhci-hcd xHCI Host Controller 480
1 2-0 Linux 3.3.5 xhci-hcd xHCI Host Controller 5000
2 1-2 Quectel EC25-AF 480
3 1-1 MikroTik R11e-LTE6 480

The problem (I think is with the channels), I can't get any channel to work except for 0 and it doesn't accept any AT commands:
[admin@MikroTik] > interface ppp-client print
Flags: X - disabled, R - running
0 R name="ppp-out1" max-mtu=1500 max-mru=1500 mrru=disabled port=usb3 data-channel=0
info-channel=0 apn="fast.t-mobile.com" pin="" user="" password="" profile=default phone=""
dial-command="ATDT" modem-init="" null-modem=no dial-on-demand=yes add-default-route=yes
default-route-distance=1 use-peer-dns=yes keepalive-timeout=30
allow=pap,chap,mschap1,mschap2

And when I go to serial terminal for channel 0, nothing happens, and I cannot type any AT command:
[admin@MikroTik] > system serial-terminal port=usb3 channel=2
failure: no such channel
[admin@MikroTik] > system serial-terminal port=usb3 channel=3
failure: no such channel
[admin@MikroTik] > system serial-terminal port=usb3 channel=1
failure: no such channel
[admin@MikroTik] > system serial-terminal port=usb3 channel=4
failure: no such channel
[admin@MikroTik] > system serial-terminal port=usb3 channel=0
failure: port's channel is already in use
[admin@MikroTik] > interface disable ppp-out1
[admin@MikroTik] > system serial-terminal port=usb3 channel=0
[Ctrl-A is the prefix key]
[Q - quit connection]
[A - send Ctrl-A prefix] [R - autoconfigure rate]
