Blocked numbers
I recently unblocked a number on my phone, they can receive my texts but I’m still unable to receive their texts, I’ve double checked in my blocked contacts and the number isn’t listed what can I do to resolve this?
iPhone 11, iOS 13
When you block a number, you can continue send messages but can't receive. I am not sure where you checked.
For unblocking
Messages --> Settings > Message > Blocked > [Look for the number, swipe left] Unblock
Phone --> Settings > Phone > Call Blocking & Identification > [Look for the number, swipe left] Unblock
