How can someone not on an original text answer my text question
How can someone else send a text response who is not on the original text from me
Question marked as
Someone can reply to your text even if you didn’t message them if they replied to an older message from you, if your message thread split due to iMessage reactivation, or if your text was forwarded by the original recipient. This is almost always a thread or contact identity issue, not a security problem. Checking Send & Receive settings and confirming your Apple ID devices will ensure everything is secure.
