Just wonder whether there is an application that can preventing the user from "mistakenly" dialing international call. A real case is: One is called by a friend abroad. His phone shows up the incoming call number as "+xxxxxxxxxx". He then "mistakenly" calls his friend back by dialing the number "+xxxxxxxxxx" from the phone call log (without realizing his friend is currently abroad).
Thanks for your help in advance.
