Truecaller is available for both Android and iOS devices.

T-Mobile's Scam Shield is a service designed to protect users from scam calls and messages. It offers features like Scam ID, which labels suspected scam calls, and Scam Block, which automatically blocks these calls. Additionally, Scam Shield provides Caller ID, allowing users to see the identity of incoming calls, even if they're not in your contacts.
