Perhaps I am missing something here, if you turn off the roaming, how do you plan on receiving a wireless signal for the internet?
Make sure you get a name and number from the AT&T Rep if you are going to "Roam" for free. I have a good friend that thought he was roaming for FREE on Verizon from NY and got a wireless bill for $1800 for his wireless web surfing in DR. He was able to talk his way out of all but $100.
Don't believe everything phone company's tell you, and get a name and extension.

I absolutely agree re not believing everything they tell you; so I went ahead and called AT&T and this is what they said: The internet and the cell phone are all bundled up together on something called GPRS internet, which goes through the GSM cell tower technology. But you can choose (on your phone) whether to use the towers or a closed wireless connection like what you might have in your home, that is password protected). And they aren't the ones that stop or start the service on your phone, but they sent me to Applecare so they could show me how to do it directly on MY phone.
SO here's the ticket - on your phone, you go into Settings -> General ->Network -> and turn "data roaming" OFF. Then you join the network wherever you are (Alisei or whatever) and it will go through regular wireless internet waves (or whatever those things are!) not through the GPRS tower, and bingo, no roaming charges.
You can actually see by an icon on the phone that you are working off a wireless or an "EDGE" connection (the latter is their cell technology, which apparently the iphone is always roaming about looking to connect to.) Both told me it is better to turn off the Wi-Fi option when you are not on line (also accessed through Settings) because it uses up battery power (because the iPhone is constantly trying to connect, which takes energy, poor thing.)
Does that sound more logical to you? I'm not sure if I am more or less confused, but I am glad I read your post because it encouraged me to go ahead and get more info. And I really trust the techs at Applecare, I've been using them for years now and they've never steered me wrong.
And I think this forum is fabulous!!!!! thx, cf
