Just picked up a Ltap 4G model which runs on the MMIPS firmware. I can't get the LTE to work but realized there is no LTE package installed and not one available for MMIPS that I can find. Any help would be awesome.

LTE package is required only for old SXT LTE (RBSXTLTE3-7).
What do you mean with "can't get the LTE to work"?
You are unable to get an active LTE connection? Does LTE interface show up into WinBox?

Yes the LTE interface shows up. The log shows no sim card inserted (I have tried every port and in multiple ways, continue to get that message). I can take the same sim card and throw it in my Ltap Mini and it works great.

Also when I try and do a scan with LTE1 it says it couldn't start - modem isnt configured yet (6)

Try the changing usb settings...
Are you trying to get a second card working or just the r11e that ships with the kit?

If you have not changed SIM slot settings into RouterOS, then ensure that SIM card is inserted into slot number 3.

If you have not changed SIM slot settings into RouterOS, then ensure that SIM card is inserted into slot number 3.

This was part of the problem. The 4G card did not work with my carrier so I had to use the R11e-LTE-US card out of my Ltap Mini. You are correct as well, slot 3 was the magic slot. All is working now. Thank you
