iMessage will not send messages, iMessage will not send messages

Is is possible that a person is blocking my iMessage? I can send to other people and they can iMessage this person. As soon as I send I get the failure message. I had been able to message them in the pas. I unused both cellular and wifi.

If that person is using ios7 beta, yes. Ios7 has a new block feature that will block phone calls and text messages. Not sure if it blocks emails, but maybe because it generally blocks the contact. Also not sure if it blocks an entire contact cars or just specific entries, but I think the entire card.

Don't know if they are using IOS7. Could be - i have heard about the ability to block with 7.

Thank you

Spot on... or most other solid DNS services

I have just had the same issue which led me hear.

I have iOS7 on an iPhone 4S.

In Settings / Messages / Send & Receive you can check your Apple ID. Mine wasn't displaying properly as I've recently changed it. I signed out, then signed back in using the correct Apple ID and password and my iMessage sent immediately.

Bingo.

Hope this helps someone, anyone........

Thanks for that all up and running now

imessage not working on Ipad 3.... I try everything (and messages are blue)....

imessage working on my iphone 4 S , messages are green.

I have iOS7 and my messages don't alert me. So strange...i have to actually go into the program to see if I have received any.

I don't seem to have any issues sending them or them being received on the other end.

Yes, I am sure that I have the banner/alrert function activated.

Any suggestions? I use this phone for work so it's actually important that I'm able to see if a client texts me throughout the day.

I cannot use imessage on my imac at all any more. It shows the word "offline" in italics for every message. I updated my password on my imac and it still doesn;t work. Advice?

It's annoying to have to put a subject every time I want to message someone. Anyway around that?

What is DNS?

my iphone 4s failed! can u help me!

Be specific. Elaborate.

Yes there is. Go to settings > messages > show subject field > off. Hope this helps.
