I have an unlocked iPhone 3G and my wife and I are coming to the uk on holiday (from Australia) Does anybody know which paid sim I could use for our month long trip? we want to be able to book accommodation etc on the road so would need the Internet. As we will be travelling from south east England to NE Scotland we would need decent 3G or Edge coverage across the uk. I looked on the Internet and see lots of companies do them but I couldn't see any with data plans. Does anyone have any thoughts ?
