Hi Y'all
Off to Bali with the family next week

. As I surf and my wife and kids do not (kids too small, wife too scared), I will be gone for a couple of hours each day and will need to keep in touch. We both have iPhones and have been looking for an app to communicate without using our SIM cards.
I realise there is no push notification as yet and the app would need too be running to communicate. I tried the early version of AIM and was disappointed and am a little time poor to try out every app
Does anybody have an app they can recommend or would we be better off just throwing local pre-paid SIM cards in each phone. Both phones are 1st gen unlocked so this is an easy fix, though I have a small business and although I'd rather not be contacted I kinda need to be available.
Oh yeah, I know Bali might be a bit touch and go at the moment with the Jemaah Islamiah boys and all, but We've weighed it up and believe we should still go.
Cheers in advance.
