Ebay was how i acquired my unlimited data plan. I was fortunate to find one from a person that was very knowledgeable on the matter. You dont even need the sim card if you are selling the plan without the ipad. The best way to do this is by going to att.com/ipadlanding and logging in using the same information that is used on ipad. At top of page click edit user & payment information. From this page, you can then change the IMEI and ICCID numbers (can be found under Settings, General, About) to the ipad the plan is being switched to. You then change the user information and the credit card details. There has to be a valid credit card on file in order for the plan to successfully renew and not risk permanately losing the unlimited data plan. The only part that I was weary about during this part was giving someone my credit card. I avoided this problem by buying a prepaid Visa card at WalMart and giving this to the person who was selling the Ipad plan. After you put the credit card information, you can change the email to the buyers email address and make a generic password. Give the buyer the new log-in information and your set. Everything went smoothly and I was happy with the experience. If anyone needs more questions you can ask me. Thanks.
