Learn how to use home dialing on your HTC One Max. 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.

Note: 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

• Go to Settings, and then tap Call.

• Tap Home dialing settings.

• 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.

• Go to Settings, and then tap Call.

• Under Other settings, clear the Home dialing option.
