When it comes to blocking unwanted texts from unknown senders, two primary solutions are available: carrier call filtering services and third-party applications like Truecaller. Understanding their differences can help you choose the most effective method for your needs.
What Is Carrier Call Filtering?
Carrier call filtering involves services provided directly by your mobile network operator to identify and block spam or scam messages. Major U.S. carriers offer these services:
- AT&T: ActiveArmor
- Verizon: Call Filter
- T-Mobile: Scam Shield
These services typically filter messages at the network level before they reach your device, aiming to reduce unwanted texts. While effective, they may not catch all spam messages, especially those from new or unreported numbers.
How Does Truecaller Work?
Truecaller is a third-party application that identifies unknown callers and blocks spam messages. It relies on a vast community-sourced database to recognize and flag spam numbers. However, Truecaller requires access to your contacts and call history, which raises privacy concerns for some users. (clark.com)

While both carrier call filtering and Truecaller offer spam protection, they have limitations:
- Carrier Call Filtering: May not block all spam messages, especially from new or unreported numbers.
