I am looking for a phone book app which will help me stop making international calls. I want to be able to selectively pick the numbers I never want to dial as I have run a huge bill by mistake. I don't want to put international barring, as I won't be able to text abroad. I just want the app to stop me from calling abroad. Does anyone know of any app or know of a workaround? I currently use Phonebook and I don't know if this is possible with this app.
