FWIW, I do have the MG21/E up and running with a static IP on our Verizon business plan. The MG21/E still isn't officially certified on the Verizon network, but you can override the APN setting on the SIM, using the local MG configuration pages to get the MG to connect to their gateway. Lots of troubleshooting with VZW, but I was able to get to the right resources eventually. APN override not needed for dynamic IP, but you may need to call support with the device specific info to get on the network if the web site still isn't letting you self-register.
