Re: I currently have a GSM phone. Will it work overseas?
Are you talking about Sim Card or Mobile Phone?In case of Sim Card most of them will not work overseas.But your cell phone will work if you insert other Sim Card of that country in which you are going.

Why shall there be a problem for a mobile phone to work overseas? If you have international roaming activated in your mobile then it is not a problem. You phone shall work very much fine.
