Contacts Prefix Fixer

This program is used for editing your prefix phone number in contact.
For example:
Your mobile phone number: 0902145545 and you want to add +84 prefix to your contact to get +84902145545.

Some phone company plans, such as AT&T Prepaid, will charge you if you dial anything other than a 10 digit number. Even dialing a 1 on a number such as 1-888-123-4567 will cause your plan to not renew. Also, your phone book may still have local 7 digit numbers in it without an area code. Such numbers will also cause your plan to not renew. This app fixes all of these conditions.

If you merge contacts from many sources, your contact phone may be duplicated. You can use this program to remove duplicated phone in the same contact name.
