      Try to configure the modem part from scratch, i.e. delete everything, reboot, then check and configure.
      Changing name means re-connect for me. I'm not FreeBSD expert, but in Linux the fixed name assignment could be achieved by udev rules, here you will need something similar. Worth to try devd.conf ?

      it has no speaker

      was related to a modem itself, not the box it is plugged in
      Here are the basics: https://en.wikipedia.org/wiki/Hayes_command_set

      M0 or M		Speaker off, completely silent during dialing	M3 is also common, but different on many brands
M1		Speaker on until remote carrier detected (i.e. until the other modem is heard)
M2		Speaker always on (data sounds are heard after CONNECT)

      BTW, E352 is not an "LTE-Modem".

        What I've noticed though: This time I get a response from cuaU0.2 instead of 0.0
        I've changed to that, tried, same error.
        It's literally the exact same hardware.

        Could be a different firmware version but it's probably configured with a different composition, the modem port listed in a different order. Try running at the responding prompt:

        at^setport?

        Some useful info on that in Andrewz's post he linked earlier.

          Good point, worth to check. As I recall it was 2 different hw mods of E352, each with it's own fw.

            Sadly "AT^SETPORT?" gives me bad English. "COMMAND NOT SUPPORT"

            CuaU0.2 leaves the following messages from time to time:

            ^RSSI: 2
            ^RSSI: 3
            ^RSSI: 6
            ^RSSI: 2
            ^RSSI: 5

            I take it that's normal? So it does do something. Sadly, I don't understand what.
            Seems like it changed the channel a few times, but I'm not getting anything else.

            EDIT01:
            Ok it does not seem to be the string. If I copy the Init String, i get an "OK" as response. Nothing after that, but I'd consider "OK" an acceptable response.

            EDIT02:
            Just checked /boot/loader.conf, because it kept telling me an error to accept some Intel license agreement (in dmesg).
            There I found something that seemed off to me..

            hw.usb.no_pf="1"

            Might that have anything to do with it? (The second pfsense has the same entry though)

            EDIT03:
            I just realized something. I figured both sticks are the same. They are not. I'll admit I've never looked that closely, but since there is no sticker on it, it took me until now to realize:
            I ran an ATI - Modem: Huawei E122
            Revision: 11.009.02.00.55
            So it is a different model altogether. Does that change anything?
            EDIT04:
            I've checked the second computer again. Here's what I noticed/what struck me as odd:

            1. It would seem that stick is recognized as modem, mass storage and disk drive.
            2. ugen0.5 looks like it keeps connecting and then disconnecting again
            3. Whatever ng0 is, apparently it keeps changing the name to ppp0 about 15 times in the output.

              OK, let me answer some of your questions.
              E122 should generally work. ^SETPORT is not available in the older models, so try AT^U2DIAG? and AT^U2DIAG=?
              Otherwise you can try installing usb_modeswitch.
              ^RSSI: 2, etc  is absolutely normal, this is how signal level is reported, it should be a command to switch this off.
              ng0: changing name to 'ppp0' is normal as well, but this should occur only once.
              Frequent disconnects are usually related to power issues and/or bad cables. Try to use relatively short USB extension cable, 15-20 cm if you have one; plugging the modem into the USB port directly is not always the best choice.

                Both give me an error, sadly.

                The setup is basically this:

                PC - NIC01 - WAN
                    - NIC02 - LAN - SWITCH
                    - USB01 - Huawei E122 - so, yes it is connected directly.
                besides Power and a KVM switch (USB), nothing else is connected.

                What would you recommend otherwise? Trying a different USB port?

                EDIT01:
                Wait.. hang on.. if I copy it instead of typing it, "AT^U2DIAG?" works.
                ^U2DIAG: 268

                  @theHubi:

                  ^U2DIAG: 268

                  This means M+CD+SD+UI

                  modem (M)
                  NAND-flashmemory drive (CD)
                  microSD-drive (SD)
                  PC UI interface (UI)

                  Try AT^U2DIAG=0  to keep modem and PC UI only. Re-insert modem afterwards and see how the ports will be recognized by the OS. Then check which port responds to AT-commands.

                  If you have a choice - try another USB port.

                    Ok now this is weird.

                    I've had it working on both machines for a while (changed USB port on the other one and that seemed to work).

                    Now after a single reboot, it stopped working again.
                    It went full circle. What is going on?

                    Edit01:

                    The first one that was working:
                    cuaU0.0

                    • but why cuaU0.2? I just set it to 0.1 ???

                    cuaU0.2

                    It's like the modem just said: "No. I don't want to any more." and quit.

                    I'm going to try removing and reconfiguring the PPP settings, but I fear that might not solve the issue.

                    Edit02:
                    I don't quite understand why the log says "0.2" on all three of them. Fact is, I've tried all three and none of them want to connect anymore.
                    I'll try again via SSH if I can get any response from AT, but I'd really appreciate some help understanding this weird behaviour.

                    Edit03:

                    cu -s 115200 -l cuaU0.0 - Connected, then does not react to anything, not even ~.
cu -s 115200 -l cuaU0.1 - Connected, does not react to AT, but reacts to ~.
cu -s 115200 -l cuaU0.2 - not Connected, I can type just about anything, but it's going nowhere.

                    Edit04:
                    After 8-10 minutes I got a response on cuaU0.2: "unsupported speed 115200"
                    What on earth broke to cause this?

                      Ok so a second reboot and reconfiguration fixed it for #1.

                          Are you also using a Huawei E352? Otherwise this should be in a new thread.

                          It seems likely you are not using that since that has it's own SIM slot. In which case what modem hardware are you using?

                          Also we are not Protectli support. If you are having a hardware issue with something they supplied you should ask them directly.

                            Out of curiosity, what does your Init-String look like?

                            Something along these lines?

                            AT&F&C1&D2E0S0=0M1

                            Because according to the information given to me:

                            M0 or M		Speaker off, completely silent during dialing	M3 is also common, but different on many brands
M1		Speaker on until remote carrier detected (i.e. until the other modem is heard)
M2		Speaker always on (data sounds are heard after CONNECT)

                            Removing the M1 at the end fixed it for me.
