I am using Virgin Mobile for some digital stuff and it works ok, I use a usb radio on a cradlepoint adapter/router which allows full configuration of forwards. Most Mifi Devices have limited port forwarding ability.. I have My Allstar machines behind it but have not really been using those linked for a while since I went to Virgin Mobile... so cannot say if Allstar is passing but I think it is. My NXDN links operate from the inside out so YMMV.

I would like to use an RTCM in a mobile environment, using a wireless ISP. The question is, does anyone have any experience with this ? The reason that I ask is; I was checking with Verizon Wireless and they block UDP ports on their 4G/LTE network . Is anyone succesfully using something else ? Thanks and 73
