I'm using my iPhone for main device, but also using WP on the side too. However, yesterday AT&T rep told me:
"Stay off the 4G network while using WP on internet. (Wi-Fi only) Because, at&t will drop your unlimited plan then. They know your using both iPhone and Windows Phone."
Could someone, please explain why I can't use both devices on the same data plan? Isn't that what the sim card is about? Is to switch from one cell phone to another?
