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 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. Under Other settings, clear the Home dialing option.
