Hi I'm trying to block sms messages from contacts with no phone number, but the block doesn't hold

Greetings guye,

Thanks for connecting with Apple Support Communities. Let's restart your phone to see if that helps. Often times this step can

resolve several issues: Restart your iPhone

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

If the issue persists, we recommend that you contact Apple Support directly. Depending on your region, you may be able to contact them here: Get Support

Take care.

I also do not have the option to report msg as junk.
