Home dialing
When you're on a trip abroad, it's easy to dial friends and family from home.
Your home country code is automatically added when you call your contacts while
roaming. But when manually entering a phone number to call, you need to enter a plus
(+) sign and country code before the number.
Using a roaming service may incur additional charges. Check with your mobile
operator for rates before using a roaming service.
Changing the default country code for Home dialing
1. Go to Settings, and then tap Call.
2. Tap Phone settings > Home dialing settings.
3. Select a country, and then tap OK.
Turning off Home dialing
If you prefer to manually enter complete phone numbers to call while roaming, you
can turn off Home dialing.
1. Go to Settings, and then tap Call.
2. Tap Phone settings and clear the Home dialing option.
