Open the group text conversation.
Tap the group name or contact list at the top.
Select “Leave conversation” or “Leave group.”
Confirm “Leave” if prompted.
If “Leave conversation” is not available, silence the conversation:
Tap the group name or contact list at the top.
Choose “Notifications” or “Mute.”
Select “Mute for” and choose a duration (or “Until I turn it back on”).
Disable message notifications for the app (if needed):
iOS: Settings > Notifications > Messages > turn off “Allow Notifications”
Android: Settings > Notifications > Messages > turn off notifications
If you want to stop receiving messages entirely and you control the thread:
Ask the group owner/creator to remove your number.
If you can’t leave and silencing isn’t enough:
Block the sender(s) who are most active in the thread.
If blocking is not desired, archive the thread:
iOS: swipe left on the conversation and tap “Hide Alerts” or “Archive” (if available)
Android: open the conversation and select “Archive” (if available) or use “Mute” instead
If the thread is an SMS/MMS group and you can’t leave:
Mute notifications and ignore the thread.
