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 while roaming.
Enter the phone number from your home country that you wish to call.
Note: If you enter a leading zero, it will be removed. If you enter a plus (+) sign before the phone number, HTC ChaCha will dial normally.
The Home Dialing screen opens and shows the country code to be added before the phone number.
If you want to change the country code, choose the country that you want from the country selection box.
Tap Done, and then place the call.
