International Cell Coverage

[TokyoT]

Does anyone know who has the best international coverage for cell phone service based out of Thailand. My current provider is the Japanese company AU, and the service is based out of Japan. Coverage is great, but I am looking to get a Thailand based provider.

I would like to be able to use the phone is as many of the following areas as possible.

Japan, South Korea, Philippians, China, Taiwan, Thailand, USA - usually the problem is related to getting service in Japan and South Korea.

Any suggestions?

My friend went to Europe last month and he used RangeRoamer. he said it worked great. He called me a few times and there wasn't much static. If your looking for an international phone service, Id go with that one. Seriously. The other ones are insanely expensive. and don't rent cell phones. Go check it out. hopefully its what your looking for.
