Has anyone successfully used a app that requires UDP packets

Sorry, guys.  No luck yet.  Today UDP port 4993 which I use to control my ham radio station, was unblocked for about three hours and then blocked again.  I have tried with no luck talking to a T-Mobile tech.  If I uncover anything, I will post it here.

When you speak to the techs, what is their response? Do they acknowledge that it's being blocked, deny it or do they react  that you have no idea what is going on and blame something else on your end?  I don't know at what level this filtering occurs. Is it at the cell site or the network? I only recently started having the issue of being blocked out almost all the time. In the past I would get drop outs thinking it was just poor cell service and I was losing the internet connection. I've also only been on T-Mobile in my car since December. My car before that had AT&T data service and that worked fine with my open spot.
