When you first go into setting and select Cellular data you will get this window that pops up.


under where it says to upgrade your device on a current account, Click on the area that says "Existing iPad Customer?"
You will then be prompted to log into your ATT iPad account. Login with the info for your current account and magically your new 4G iPad will be the device active under your Unlimited Data Plan.


As you can see you have the option to keep the unlimited plan on the new iPad 4g.



______________________________________
How do do it via ATT website,

First you will need both to log onto AT&T’s website and transfer your account over to your new iPad. (If you don’t know or forgot your AT&T account password for your iPad, you can have one re-issued to you.) You will also need to know your new iPad’s IMEI and ICCID settings. These are both located in the General settings on the iPad under the About section.

• Log on to www.att.com/ipadlanding to access your account information.
• Click on “Edit User & Payment Information” and then select “Update Device Information”.
• Enter in your new iPad’s IMEI and ICCID settings and click “Next”.

This process should take effect instantly and will not change or affect any other information on the plan. It has been reported that original iPad owners that have been able to retain their unlimited data plan with AT&T will be able to keep this plan at the faster 4G LTE speeds. If you are unsure or just want to talk to an AT&T before doing the transfer, you can always call 1-800-331-0500 for assistance.

This should be for those who have an iPad with a 3G account. iPhone accounts are not the same type of accounts as they include voice.

Yes, If you have a grandfathered unlimited iPad Data plan. This will allow you to transfer it over to your 4G iPad in effect giving unlimited 4G data.

Guy I got the screenshot from did it and it worked. He first asked ATT and they had no clue, he then purchased a new 4G Simcard from ATT to transfer the account to the new simcard type before figuring out that these simple steps could be done within the iPad itself to transfer his account to the new 4G iPad. He then did just that and returned the 4G simcard that ATT thought he would have had to purchase.



I'm waiting for my iPad to be delivered, should come at any time and once that happens I will be doing thing and post about my success of transferring my unlimited data plan....



I also just posted how to do this via ATT website. doing it via iPad would be easier.

I did, and posted details on the other post.

I just transferred mine.

go into settings like the screenshot above and select that you have an existing account.
Sign into your account and it will pull up a list of available plans for the new iPad and unlimited for $29 is an option since you are grandfathered in.


I took of screenshot of the list of plans and it allowing you to select unlimited, ill post it once i get a chance.


PS. it looks like there is no LTE in my area (Miami,Florida). It says its connected to 4G(not LTE) network but I'm getting speeds of less then 3mbps

What about Verizon? I have an unlimited data plan on Verizon and my iPhone is on that. Can I put my 4G iPad3 on there (verizon version)?

Sorry for the thread break....

Phone plans do not transfer to iPads on either carrier, this is only moving iPad account to new iPad.

Unfortunately, mossfur, the unlimited plan is only for those that got grandfathered into it (it was available at the very beginning days of the iPad, but the carriers stopped it in the early summer of 2011). You can't get it any longer.

As far as moving your current plan over, I really don't see why you can't follow the same steps here. To be safe, however, I'd check with your carrier - they would be the ones that would know for sure (cause I've been known to be wrong in my assumptions before! ). It may be that you'll have to cancel the plan on the old and re-start it on the new...

currently they are not throttling the LTE iPad plans, however that does not mean they couldn't start doing it at any time.
