hi, forum. I just want to know if the 3G plan settings will be enabled on the iPad even if the SIM card isn't connected on the device. I mean, if it's unlocked, the options for buying a plan should only be available with the AT&T SIM card. Let's say this setting will always appear even without the AT&T SIM, but I would want to use the iPad with another carrier. then I'll have to negociate the plan with the carrier but I won't be able to cancel it from the iPad, right? the settings for AT&T will always appear even with another SIM card or without a SIM card? can I still use another carrier even with these settings appearing? thank you very much.
