Hello! Anyone have made this modem work?
Modem desn’t respond on serial-console, speed of usbport can’t be changed for this driver.
Those products are not MikroTik products
Oh really? This products are supported by Linux, so MikroTik should can works with it.
No offense, but I think you do not have a clear idea of how things work.
Neither I, but certainly this is a support forum only for hardware and software MikroTik.
OK, OK, it’sa Joke… 
Next time remember to write what RouterBoard you use with the modems.
This is the best answer for your question:

I’ve send supout file and i’m waiting for support. Seems that modem is corectly recognised, but doesnt work.
I hope the MikroTik staff can handle your request.
I think the same 
I think that it’s a little bug with this driver
Seems that when i switched SIM card directly into modem AT commands starts work! Data channel 1 (info channel 0 or 1)
