Get IntlPrefix old version APK for Android
Automatic addition of dialing prefixes to outgoing calls!
IntlPrefix automatically adds dialing prefix to outgoing phone calls. This allows you to store all your phone numbers in international "+country-area-number" form, and IntlPrefix will automatically replace "+country" by the user-defined prefixes for domestic and international calls when calling.
IMPORTANT: if prefixing does not work, use the "Alternate conversion method" option (some handset models do not respect Android standard and need this option).
