I have Call Blocker by Embware and it is working just fine, but is it possible to block an SMS and to make the sender not to see that the message is delivered? I want the message to be pending for sender. Is it possible?
The reason why this is not possible is that by using this application, you block the SMS from your point of view. From the sender point of view, the sending process was completed successfully and there is no way to change that.
