J got a new cell phone and I thought I'd pass the number along. From the States (or Canada or Germany for that matter) dial 011 +84 (905) 04 3617. She's 12 hours ahead of Eastern Time and 13 hours ahead of Central. So if you're in Central Time and you call her at 9 at night you'll be talking to her at 10 am tomorrow. This is particularly useful if you want to bet on sporting events, as they will have already occured once you cross the international date line. or something like that.
You should be able to get a calling card that will give you something around 30 minutes for $5. I'd suggest going to an immigrant neighborhood and asking at a corner shop. They should be able to help you.
Also, if you didn't notice, J (nguoi My) also blogged once.
