How do I know it is working?
You have to test it.
If the Status screen in Simple Call Blocker indicates that the extension loaded successfully, then it is working, and it is blocking the number of phone numbers the Status screen says it is.
You can test if it is working if you have another phone to call your iPhone with.
- In Simple Call Blocker on your iPhone, add the phone number of the other phone to the block list.
- Use the other phone to call your iPhone.
- Your iPhone will not ring. (Your voicemail may pick up, depending on how it is set up.)
