Group Texts not working on iOS 9.0.2 with my 6+.

I Am having the same problem since the 9 update and 9.0.2 bug fix. I am going to Apple Store this morn but am not optimistic about them helping. I wish I had not updated to 9.

Same exact problem here. Atrempted same things. I use group messaging constantly at work and my iPhone problem has made me a lagging team member. I've seen a few threads with users having this problem but it looks like no one has a solution. Seriously Apple, I'm begging for AT LEAST a temporary solution so I can get work done!

Same problem here. Mine started with iOS 9 update and I'm on 9.0.2 and seemed to have gotten worst! My wife had iPhone 5 and it's also happening on hers. Apple are you even reading this?!

Same issue on my AT&T 6 plus. Worked fine till 9.0 (then subsequent 9.01 and 9.02) update then group mms starting failing in the same manner. After all kinds of resets and even reset as new iphone problem still persist. Also had issue of receiving text from "unknown" with message "service denied" or "message unavailable"

After a long wait at the Apple Store, I received a new (service) phone. Group MMS worked for about a day then same problem returned. I also have frequent "This cable or accessory is not certified and may not work properly with this iphone" even though nothing is connected. This message happens 20-30 times daily. Apple advisor had be do a complete reset again, via iTunes and even though the phone showed 9.02, iTunes did not recognize the version and reinstalled 9.02. All the problems still continued to occur. The next step, today or so will be to get a new in the box iphone 6 plus and see what happens. I'm not that hopeful this will resolve the issue. Does anyone know if this problems exist with the 6s plus running 9.02?

Also spoke with ATT and they have submitted a work ticket to see if there is an issue on their in. 24 to 48 hours before I may get answer

Same issues here. Rest of my family did not update to 9.0.2 and they are working. We all have 6+.

i was told yesterday to enable iMessage on my iPhone6+ currently running 9.0.2 to see if it fixes this problem. I have iMessage set to OFF, always have because I do not like all my texts going to all my apple devices, but was willing to try anything at this point. I disabled iMessage on all of my other apple devices and when I enabled it on my iPhone, I only chose my phone number to be able to send/receive texts (NOT using my Apple ID/email)...and so far it seems to be working!
