My wife and I are AT&T Wireless business customers. We both have iPhone 3GS devices. Today we traveled from Utah to Nebraska by way of I-80 through Wyoming, and at about 10:45 PM CST my wife got a page saying she was in violation of the domestic data roaming TOS. My wife used her iPhone to send an email and check Facebook on our trip and that is all. Each time she did so her iPhone said AT&T E. I called support and they said that we used (his term was millions of kilobytes of data). This puts us in the GB range of data use in a 12 hour trip period. This was a manager who said this. He also said we did not roam, but did use off network resources. Isn't the whole definition of roaming using off network resources?! I know full well what the contract I signed said about domestic data usage off network, and I would never use my phone if it didn't say AT&T so that I would not run afoul of this TOS policy. Does AT&T have the right to penalize me and threaten to terminate me for off network data usage when my phone says AT&T and not some other carrier? Seems rather ridiculous that they could penalize you when you are for all intents and purposes on a domestic AT&T network, or otherwise have no way of telling. I have never seen my phone say anything but AT&T. Thoughts anyone? Should I take this to my states attorney general, the BBB, FCC and The Consumerist so that others are not bullied by AT&T? I am getting no satisfaction from AT&T, just a lot of rhetoric and run arounds.
