    What's the model number of your phone? If you're not sure just look under the battery.

    Looks like that model is intended for Telus, Rogers & Bell - Canadian variants. I don't know what would happen if you tried to load the AT&T firmware; it's generally not a good idea to try something like that.

    It actually is designed for Claro cell phone service from Puerto Rico

    The firmware for that variant can be found at http://samsung-updates.com/device/?id=SGH-I747M - I wouldn't recommend loading anything other than what you find there.
