Sim card in SE Asia
March 1, 2011 8:57 AM Subscribe
I'm going to be in SE Asia and would like to buy a sim card from a carrier that will work across the region. Specifically we'll be in Hong Kong, Cambodia, Thailand and Malaysia. Is there a carrier that operates in all those areas on a GSM phone: 850/900/1800/1900? Do I need separate sim cards for each nation?
