Has ping / tracert been blocked on 5g network?

The blocking/failure of using the ping utility seems to vary from one location to another. Here in east TN we had a period of time when it was failing to work but now it does. More than likely there is a configuration parameter in place to block ping packets. T-Mobile can run it down if they are motivated to do so. They may not be aware of the behavior in that location. Once they had enough complaints here they addressed the behavior and now it seems to be resolved. Well, it works here. You might try doing an IPv6 ping vs the IPv4 ping and see if there is a difference in behavior from one to the other. It might take a call to T-Mobile support to possibly get headway.
