Disabling overseas calls/data

[iantresman]

I'm travelling overseas and do not want to get ANY foreign phone charges. But I do want access to WiFi.

On my Samsung Galaxy Portal, what do I need to disable (and how), so that I get no phone calls, data access, voicemail (have I missed anything?).

Can I do this from settings, or is there a clever App that can do this easily?

Hold down power button and choose Airplane mode ( or flight mode) this will turn off all the phones radio signals. You can still turn on wifi and it will work. Just done this all myself.
