Traveling internationally with an iPhone can be extremely expensive. Even if you arrange for an international plan with your provider, it’s possible to find a staggering bill at the end of the month. Your best bet is to disable cellular data and restrict Internet access to Wi-Fi, but how can you be sure you’ve set your iPhone up properly? It’s easy with Airplane Mode and the Wi-Fi settings.
Handy tip from Dave Caolo on how to avoid great big roaming charges on your iPhone. I actually didn’t know you could enable Airplane Mode, but still have Wi-Fi turned on…I guess it makes sense when you consider you can have inflight Wi-Fi on some flights now, it just never clicked in my head.
