Sprint contact - Mobile network block DNS

Thu Nov 19 18:28:56 UTC 2020

I'm looking for a contact at Sprint (or T-Mobile?) mobile networking, if 
someone could please contact me off-list.

I help run a service that relies on being able to make DNS queries via 
standard UDP directly to particular servers, and recently we've been 
seeing all the packets silently dropped on Sprint with both iOS and 
Android devices.
