To customize plus code dialing

You can customize how phone numbers that begin with a plus “+” sign will be dialed.

1.Tap Start > Settings > Personal tab > Phone > Services tab.

2.Select Plus Code Dialing, then tap Get Settings. The following screen then appears:

3.To place local and international calls from the United States, select Enable.

When you place calls, the “+” sign at the beginning of phone numbers that you dial will be replaced as follows:

•When you enter a long distance phone number that starts with “+1”, the “+” will be removed and the rest of the number will be dialed. For example, if you entered +1 416 123 4567, the number to be dialed will be 14161234567.

•When you enter an international phone number that starts with a “+” followed by a digit other than 1, the “+” will be replaced with the United States international dialing code, which is already set by default. For example, if you entered +58 212 123 4567, the number to be dialed will be 011582121234567.

4.To place calls to the United States from another country, select Disable and change the International dialing code to the one used by the country where you are in.

So when you dial a phone number that starts with “+” followed by any digit (0 - 9), the “+” will be replaced with the international dialing code of the country where you are in.

Tip If you modified the international dialing code, you can tap Reset to change it back to the default.
