Hello, everybody. This is the first time I?ve posted here, and I have a question about telecommunication abroad. I will be visiting Thailand and Malaysia for about three weeks, doing some relief work and taking a lot of pictures. I wanted to know if anyone can tell me if using my cell phone is a possibility. Since I am not sure of my service?s roaming charges or international rates, I was also considering buying a calling card. Does anyone have any recommendations?
You should be able to use your mobile in Thailand and Malaysia. Network coverage is pretty good. You will have to check with your service provider what the rates are as using it can be expensive. Getting a sim-card locally is easy enough, but if you are using it to call out of Thailand/Malaysia it could be expensive again. It is probably cheaper just to buy an International phone card and use that, then you don't have a horrific phone bill when you get home.
Malaysia and Thailand use the GSM 900MHz and 1800MHz bands for their mobile network.
As far as I know, these two bands are not being used in the US.
However, many new generation phones out there do support multiple bands. If your mobile phone supports GSM 900MHz or/and 1800MHz, then yes, you can use it in Malaysia and Thailand.
Anyway, most mobile phone networks in Asia are on GSM900/1800, with the exception of (if I'm not mistaken): South Korea, Japan (some networks), and certain networks in China (any more?). - Correct me if I'm wrong.
