Hello, I'm overseas and I only have a Chinese cell phone with service from China International. While I was in China I got the service to make international calls, but I don't know if that means if I'm in Taiwan or Hong Kong if I can still use my cell phone?

You need to check the GSM frequency band - that's what determines if you can use it in another country. Taiwan and HK uses 900/1800 and other 3G ones. It should work.
