How to tell if someone has blocked your calls on IOS 8.4, iPhone 6?

I'm not sure if my boyfriend has blocked my number. He has the same phone as me, iphone 6 and is also on O2. When I call his number my phone instantly disconnects before even ringing? I thought that even if you had been blocked it would ring once or twice and go to voicemail. I can call other contacts on my phone fine. Have I been blocked?

Sounds like maybe he lost it and the whole phone has been blocked. Try ringiing it off a friends phone maybe?

There isn't enough detail in the question for me to determine how long this has been going on. The same thing that you're experiencing happens when the person's phone dies as well. I would try calling it from a friends phone or better yet, ask him in person.
