How to Block Scam Calls on Your iPhone 13 Pro Max
If you notice an increase in "Scam Likely" calls on your iPhone, it may be because you are a T-Mobile (or Sprint) service customer. T-Mobile uses technology to compare incoming calls to a list of known scam calls to provide the "Scam Likely" designation.

On your iPhone, go to Settings.
