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.
