  • They will see that messages are not delivered, but won't know why.
  • They will no longer be able to see your Last Seen and Online information.
  • Messages they have sent you will not be deleted.
  • Message you have sent them will not be deleted.
  • You will not be removed as a contact on their phone.
  • They will not be removed as a contact on your phone.
