Sorry but this just isn't true for everyone. I have an HTC EVO android phone with Sprint and I use it every time I go to Santiago to see my wife. I usually stay for 10 or 11 days and my bills have been about $80-100 using the data ALL the time. I have a translator app I use very frequently when I need to look up a word and I have never had a large bill. I don't know if it's the carrier or what the deal is but just wanted to say some phones are OK. To be clear, I made very few voice calls on the phone but I DID make a few and still the bill wasn't that bad.Not just the iphone...any 'smart phone', androids and crackberry included included. I don't even trust 'airplane mode'. Go into the menu and disable all data roaming. No internet, no satnav, no email, no nothing. Just phone calls and texts. Leave it on the charger and check it twice daily for important stuff. A $20 Claro phone and the occassional $250RD card has kept me in the loop for years.
GF wants to phone stalk me to make sure I'm not having a good time? Go ahead, I've got free incoming and she's got a $300US bill. That only happened once LOL.
