Sorry Tuts! I can't answer your question but have you done a search on the forum?? I just had a quick peak and there's a lot of threads to do with mobiles...
The first thing to worry about isn't the sim card (Which probably won't work in the US) but your phone. In different countries, phone are connected by different frequencies. Your best bet is to have a triband phone.
You'll definately need a tri-band phone with the itinerary you've outlined. Check with the manufacturer of your phone for the GSM frequencies the phone will operate on.
GSM stands for Global System for Mobile Communication. It's a communication standard in three frequency bands, 900MHz, 1800MHz and 1900MHz.
In AUSTRALIA GSM is 900MHz band, while the 1800MHz band is referred to as PCN. GSM 1900MHz operates on networks in the USA, South America, Asia and Africa.

As far as I know, Asia Pacific (with the exception of Japan and Korea) is on GSM 900MHz and 1800MHz band, not 1900MHz. This means any phones from the UK/Europe can be used here without any problems. Just make sure it's not SIM locked if you intend to use local prepaid SIM here.

thanks for all the useful info(a little baffling)

Hi Tuts,
You would also need to make sure that your handset is unlocked otherwise no foreign sims will work in it. Phones are locked to the operator they were originally sold on ie vodafone-o2-orange, to make it harder for people to switch network. Try the below website to unlock your phone - it is one of the few sites that lets you unlock your phone for free, although it has only a few new models on it.

With your phone unlocked you can simply buy a sim card in whatever country you are in and pop it into your phone - simple! you'll save a forune on roaming charges too.
Hope this helps
