I had the original iPad on unlimited plan. Bought iPad 2, and followed the instructions from ATT rep ... just switch the sim cards.
I switched the sim cards first thing ... there was no plan associated with the new sim card before I switched it.
So all went well. My iPad 2 picked right up with my original unlimited plan.
But, my original iPad ... after the new sim card was inserted in it ... showed 3G service, with antenna strength reading. What was going on? I turned off both devices, did the switch, and turned them on ... I would have assumed booting up the original iPad would have recognized the new sim card, in fact, Settings -> General -> About -> Cellular Data Number was listed as "unknown", so it definitely should have been using the settings from the new sim card ... yet I had 3G access!
Did I only have the remainder of the current cycle's plan on the device? Could I have had unlimited data on both iPads?
Since I was selling my original iPad .... I did a reset to return it to factory settings .... however, when helping the buyers set up a 3G plan on the device, I saw that it really did not clear EVERYTHING out associated with my original plan .... as I had the two options: USE EXISTING PLAN or START A NEW PLAN.
That made me nervous ... they started a new plan of their own on their credit card, and, after that, the option to use the original plan seems to have went away.
All seems well ... and I was selling to relatives ... BUT, I'd like to know more details about all of this .... have others have similar experiences? Thanks for sharing.
