Best Phone for South Asia (Study Abroad)?

Hello everyone,

I am going to be studying abroad this upcoming Spring in Hong Kong. I don't plan on bringing my Verizon cell phone with me because of the outrageous rates Verizon charges to use the phone abroad. I was hoping anybody could suggest a good temporary (5 month) phone that would allow me to receive and accept texts and calls. I plan on staying in Hong Kong but also travel around to neighboring countries (such as Vietnam, Taiwan, Singapore, etc..)

From what I understand, I will have to get local sim cards in each country. I hopefully don't want to have to get a new cell phone in each country as well! Please suggest feature phones and smartphones if possible!

Any suggestions? Thanks in advance!
