Choosing an AT&T data plan for your iPad
AT&T offers two data plans for the iPad based on the amount of data you will likely use during a 30-day period: $14.99 per month for 250 MB or $25.00 per month for 2 GB.
How much data will you need? If you stick mostly to e-mail, general Web browsing, and watching a YouTube video once in a while, the 250 MB option should suffice. Watching an average YouTube video uses between 5 and 10 MB of data. The iPad will default to using Wi-Fi if a signal is available, so that even if your 3G is enabled, browsing in a Wi-Fi environment won’t eat into your data plan.
If you would like to enable the 3G cellular service on your iPad, tap the Settings icon, then Cellular Data, and then View Account. You may want to try the lower-priced plan for a month to see whether it meets your needs. There are no penalties for deleting your data plan or changing it mid-subscription. Also, with the 250 MB plan, the iPad will let you know when you’re about to reach your data limit. You’ll get three alerts — at 20 percent of 250 MB remaining in your plan, 10 percent, and zero. You can choose to ignore the alert or add another 250 MB or upgrade to the 2 GB plan. If you exceed the amount of data in your domestic data plan, your plan will expire, but it will renew automatically at the end of the 30 days.
Data plan charges will appear on the credit or debit card bill that you used to set up the account. The subscription renews automatically, and Apple will send you an email notification each time the plan automatically renews. To change or delete the plan or check the amount of data that you have left, tap the Settings icon, and then Cellular Data. You will then need to enter the username and password that you used to create the account.
