Apple - Is there a way to "unsubscribe" from group texts in iOS?
As Messages and SMS integration + iMessage is designed today, this can not be done.
What you could do is:
- block the people and leave SMS / iMessage enabled
- place that conversation on Do Not Disturb so you don't get notifications from that group
- enable no notifications for either SMS or iMessage
- turn off iCloud Messages entirely
- disable SMS entirely
Just as you can't block a number or email from sending you an iMessage - there is no technical way to get others to not send you a group message (other than by exerting social pressure to exclude you from further communications).
I haven’t been able to find anything playing on my phone, and several forum posts suggest that it can’t be done:
On Mac Rumors, sla252 writes (November, 2011):
Just got off the phone with Apple tech support. They admitted there is no way to remove yourself from an iMessage group chat. The tech guy says the best thing we can do is go to http://www.apple.com/feedback
There’s also a Reddit thread in which huntard713 suggests (October, 2011):
Settings-Messages. Turn group messaging off.
It's now November 2011 and I can’t find this setting on my iPhone, and this was in response to a slightly different problem (about who sees the other participants in a group iMessage, so I don’t know how effective this.
I’m sorry this doesn’t really answer your question; for now at least, it looks like you can’t leave a group iMessage.
The only way to end the group chat is have everyone delete it of their iPhones's. To do that, slide your finger over the chat, where the list of conversations are. That only deletes it off your iPhone, so everyone will have to delete it off their iPhone. Some people will keep talking there, so everyone would get it back. If you don't send any messages in the chat, and tell the other people not to talk there (In private message), eventually people will stop texting in the chat.
It's a bit overkill, but you could block that sender (and others that keep the thread alive) using settings app and Messages blocking settings.
