Text Blockers

Reaching out to people today is easier than ever due to the abundance of mobile phones. And while this may be an asset, it creates a solid ground for phishing crimes and spam messaging. Aside from bothering recipients, these kinds of messages can also steal important personal information from mobile devices.

Thankfully, app developers created text blockers to ensure a secure mobile experience for users. A text blocker blacklists text messages and calls from unwanted senders. Let's say you accidentally subscribe to a text message campaign and cannot opt out; these will help you block the messages. 

You’ll find numerous text message blocking apps for iOS and Androids. Here are the best SMS blockers for both operating systems.
