Is there a USB device that will plug right in say a RB751 and allow access to Internet over the cellular network on say Verison or AT&T with an account? Has anyone done this?

Hi!

I use a ZTE LTE MF820D(i think) USB modem in a RB411U, and i get my data over a celluar network.
Now i have weak signal, but i still get 11,42 mbits download, and 10,02 mbits upload speed.

take a look at this:

Got a Novatel USB551L for Verizon. It works fine on Windows PC. When I plug it into a Routerboard 751U-2HnD the router finds it. Mikrotik gives options of:

PIN
User
Password
Remote Address

What do I do with all these to get it working?

Bump.

First gather all the data from the Windows application. You need to disable the PIN code check on the SIM if you have one. It's easier to use it without PIN. Next you should obtain the APN for the connection. It's saved in the Windows app in the profile. If username & password is used also get those ones as well. Next fill the following tabs: APN, Username & Password (if you have these configured in the windows app) and enable the ppp-client. Before you can modify the logger and insert debug to memory to be able to read all the debug messages for both async and ppp.
