Edit Prefix Phone Number

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.

Note: If you have a big contact list you need to wait for a few minutes. After completed update you need to recheck your contacts list. In some case, the result is failure but contacts are update successful.

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.
