Currently shows “Not Supported” in the hardware list. Any chance it will be? I have a need to make one of these work as a backhaul in a remote situation where the current link is via consumer satellite. Would much rather use Mikrotik equipment than Cradle Point.
if it says unsupported then we will not be able to add support for this modem in the near future as well.
Maybe you could look for another modem that could work ok with RouterOS.
The VL600 has external antenna connectors 
The only other Verizon USB stick you support is the “4G LTE USB Modem 551L” which, from the online reviews at Verizon, appears to be a total piece of junk.
