iMessage not working with selective iPhone contacts!

Having the exact same issue, started last night. iMessages send from my mac but not my iPhone, and now i've noticed I'm not receiving every iMessage sent to me either. Tried everything I can to fix it with no luck

SAME!!! I'M GOING CRAZY!!! Since this morning I can't send iMessages to select people but all the rest of my contacts go through as usual!

I thought maybe the iMessages aren't sending to phones that haven't updated to IOS 9.0.2..?

I really hope this problem gets figured out!

I have the same problem! It only happens to a couple of the people I message, but it's still extremely irritating. I updated my iOS last night and it started happening this morning. I hope they fix it soon!

I just talked with Apple Support

I was telling the techie that my boyfriend was sending iMessages to me but when I replied they sent as texts.

He said he thinks the problem might be on his end.

Go to Settings > Messages > Send and Receive and make sure your phone number and Apple ID E-Mail are checked

I will talk to my boyfriend later and see if this resolves the issue

I'm having the exact same issue!!!! In the process of restoring my phone from backup but it's been driving me nuts that I only have the problem with certain contacts. Apple please help!!

I'm having the same issue! Please let me know if you get an update on how to resolve this!

Im having this exact issue and it started last night. Some of the people I use imessage with are totally fine and others are just going through as texts. These are people that I iMessage every day and suddenly, beginning last night, most of the messages for a few people will only go through as green texts messages. I did all the things you did to try and fix it and it seemed okay earlier today but the problem is back tonight.

My phone was sending double messages, too. the original imessage would go through and then a duplicate text message. It started last night.

I thought of something today - and I wanted to see if everyone else here had the problem. I bought my iPhone 6s on the first day it came out - I received it in the mail from AT&T. They did not include instructions - but I never activated the new SIM card with the phone. I just put in my old one. Today I logged into my AT&T account and it said that I cannot make plan changes until I activate my new SIM card. I wondered if this may be causing the problems.

I called AT&T and put in the new SIM card. I'm wondering if this may have been the issue. I work in a high-rise in Chicago with terrible reception so iMessages sometimes do not work because of that - so I cannot tell if mine has been fixed yet. I will determine better when I get home. But I wanted to bring this up as something I noticed. I'll definitely post a follow up to this if it works...

Mine suddenly started working, too, right in the middle of a conversation. It's been working with everyone I text for the last two hours.
