What 29 hours of Scam Shield looks like on T-Mobile
What you see below is a rejected call log from T-Mobile’s Scam Shield with 89 entries over 29 hours and about 4 entries I removed in the white space at the bottom.

I’m not saying T-Mobile’s Scam Shield blocked 89 spam calls over 29 hours, but it logged that it did. Primarily from the same 4 numbers. It also let several through.
It’s not particularly good, and there’re no methods to investigate a call, only report and block a number. I happen to get a phone call every day spoofing my work’s main number and attempting to get money for a fake police charitable organization that has a really convincing robot talking to you. I’ve gone all the way to network ops before getting dropped.
*sigh* spam is here to stay because they just use landlines and change their numbers, which evidently bypasses STIR/SHAKN.
