Is it possible to block a number so I can't call it?

Long story short, I went through a really bad breakup and I want to know if there's a way to block it. I don't want him to just not call me, but I also want it to be impossible for me to call him if I'm ever in a moment of weakness. Also, is there a way to block a website on my iphone so I can't go to it?

When you find the answer let me know

You can't block a website from an iPhone. You can select to send his calls directly to voicemail.

Your local phone company or provider CAN do this. You'll need to plead your case to them and hope they're receptive.

Change the mobile number you. Use an aplication for unwanted calls
