Normally, in default calling application of iPhone ,I open number keyboard and pressed *100*stringnumber# (example *100* 12345678989 #), and press call button , it make a request to add money to my sim card account.

Now, I make an app, that it scan the string number auto by camera, and I want after scan that string, it can send the request to add money like the way in calling application.

I make an URL scheme with string: "tel:*100*stringnumber#" and send it to open calling app, but it didn't work, I search and know it just for dialog a phone number.

Is there any way or syntax to do that?
