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 make calls to your contacts while roaming.
Enter the phone number or first few letters of the contact's name.
From the list, tap a contact to call.
If you selected a contact whose phone number has a leading zero,
HTC One will automatically prepend it with your home country code when dialing. If there's already a plus (+) sign and country code before the phone number,
HTC One will just dial as is.
Note: HTC One dials as is and does not prepend your home country code when you call phone numbers that are not stored in
HTC One. When manually entering a phone number to call, you need to enter a plus (+) sign and country code before the number.
