Be sure to leave "mobile network" off so that your phone doesn't register on a foreign network. If it does, you'll be receiving a large bill for voicemail forwarding.
Switching off the local mobile network will insure you do not attempt to use it while making a call. If you move away from the Wifi source, you will experience a dropped call instead of a normal hand over.
Your question is too vague and FYI it may not work at all. When you say "overseas" you need to specify a country. It doesn't work everywhere, like China and many other places.

What do you mean? It will work nine stories below the ground in Afghanistan so long as there is an open wifi signal :P
