how to make a local call from address book overseas?

I have a pearl, and I'm currently in vietnam. I'm just wondering if I can make phone call from my address book without using just the local number? Right now, if I make a call from my address book, it would automatically add the (+1) in front of the phone number? How do I take that (+1) off?

It will always dial that +1 unless you can get a local device from vietnam.

That +1 is the US country code. If you just dial the area code and number does it work?

If need be, I think you can go into the Smart Dialing options and remove the +1 from country code and leave it blank.
