Currently, if customers might be tagged as Potential Spam on the T-Mobile network, they will have access to the Watchlist in the customer portal which will tell you if you have been tagged on the T-Mobile network.
If you would like to know if your calls have been tagged as scam or spam and across multiple networks, we do have AFFIRM Reputation Management available to Annual Contract customers. To learn more visit AFFIRM® Reputation Monitoring - Caller ID Protection | First Orion
