Contacts Prefix Fixer 2.1

This program is designed for editing the prefix of phone numbers in your contacts.

For iOS users, the application can be found at: Contact Prefix Fixer.

For example, if your mobile phone number is 0902145545 and you wish to add the +84 prefix, the contact number will be changed to +84902145545.

• Some phone plans, such as AT&T Prepaid, have specific requirements for dialing numbers. Any deviations, such as adding extra digits or not using the correct format, may result in charges or plan disruptions. This app addresses such issues by ensuring proper number formatting.
• If you find duplicated phone numbers in your contacts due to merging data from different sources, this program offers a solution to eliminate such duplicates under the same contact name.

This version represents an upgrade from the Change Prefix Phone Number tool, accessible here.

Furthermore, this upgraded version provides enhanced compatibility with various CPU types; however, it may result in a larger application size.
