You can block text messages on your iPhone from any number that you don't want sending you messages.
Blocked numbers will still be able to text you on their end, but you won't receive their messages.
You can also filter out messages from unknown senders to limit spam texts.
Your iPhone allows you to block text messages from any number on your device in a few simple steps. You can block contacts already stored in your phone or unknown numbers not stored on your device.
When blocked, the owner of that phone number won't be able to successfully text or call you, and they won't be informed that they've been blocked.
Here's how to block messages on your iPhone.
