    I'm no noob, I've been around the forums for a while, but I am unsure about some SIM stuff (because I've never had to worry about it---I'm legit :D)

    I currently have an iPhone 3G on AT&T.

    If I upgrade to the new iPhone this summer, can I give my 3G to someone who is currently on AT&T's $39.99 plan with no additional features, and put their current SIM in the iPhone? If so, can they continue on their plan without adding data (no comments on "Why would you want an iPhone without a data plan?"!!!)

    Thanks for your help in advance.

    Not legitimately. They'd have to activate it in iTunes when they put their SIM card in, and it would make them choose a rate plan.
    If you unlock it, however, that's a different story.

    I thought the rate plan selection in iTunes was only for the original iPhone. I never did any of that when I bought the 3G.

    You are correct about iTunes and the original iPhone.

    Now back to your original question: Yes you can give your current iPhone 3G to someone and they can use it without the iPhone 3G data plan. They will not be able to use Visual Voicemail.

    If they don't have a data plan on their line then they may be charged on a Pay Per Use (PPU) fee for any data that the iPhone 3G uses. This can be prevented by having a WIX Block placed on the line. Just have yoru fried call Customer Service before they move the SIM and ask to have all "internet" data blocked. The AT&T term is a WIX Block and it will only block data but not SMS Txt before you ask, so your friend can still text.

    You can test this today, just put your friends SIM in your iPhone 3G and it will work. There is no need for the iTunes "Activation". That part is required for the original iPhone since the iTunes "Activation" paired the specific SIM with the iPhone. That's why the other poster indicated that if your iPhone 3G was unlocked then you had no worries about SIM usage or Activation. In your case with the iPhone 3G unlocking is really only an issue if your friend does not have AT&T and for example wants to use the iPhone 3G on T-Mobile. :(

    AT&T will know that the iPhone 3G is being used on your friends account, the phone will turn them in everytime it connects to the cell network. Currently, AT&T is sending SMS Text messages to iPhones that are using an invalid data plan. There have been several reports that AT&T will begin to make forced changes to the data plans, as of today this is still just a rumor until someone posts a copy of a bill. AT&T can and does have the legal right based on your contract to require the proper iPhone data plan on every iPhone. While I don't agree that you should be forced to have a data plan if you don't need it, I can understand AT&T wanting you to pay for what you use. Some individuals are using the $15 MedaNet plans on the iPhone 3G and I don't think AT&T likes losing the Revenue. :p

    Thank you very much for your help. You say that AT&T is CHANGING MediaNET plans to unlimited data plans, but if the user opts out using the WIX block, do I need to be concerned with AT&T automatically ADDING a data plan to the user's account at some point AND/OR the user being pestered with text messages or other notices from AT&T?

    This issue continues to develop and the latest internet rumor is that by April 30 AT&T should begin making changes, again as of today, this has not happened.

    The iPhone rate plan states the following:

    Data Plans: An eligible data plan for iPhone is required. This data plan covers data usage in the U.S. and does not cover international data usage and charges. If it is determined that you are using iPhone without an eligible data plan, AT&T reserves the right to add an eligible data plan to your account and bill you the appropriate monthly fee.​

    The purpose of the WIX Block is to prevent pay per usage charges if you don't have a data plan on the line. It will not protect you if AT&T decides to inforce the terms.

    OK, thanks. I will have to seriously reconsider my plan.

    If you unlock it... Though without data, the iphone is just another phone... can't really do much besides the phone and music
