DataConnect 5GB for 4G LTE Tablets (2-Year)
Once the allotted amount of data is exceeded, additional data is provided for $14.99 per 250MB on the 250MB Plan, and $10 per GB on plans 2GB and greater. To manage the amount of data billed as part of your AT&T subscription, we recommend that you use available Wi-Fi connections when possible. If you exceed the amount of data available in your AT&T plan, we may have to temporarily interrupt your ability to connect your tablet over the AT&T 3G network. This interruption will last for the remainder of the billing period; or until AT&T receives approval to allow additional overage charges from an authorized contact for your account. Pay-per-use international usage is included.
These data plans require a 2-year agreement to purchase the tablet at a discounted price. If you purchase one of these data plans, you may change to a lower-priced data plan only after the 2-year agreement is met. The 2-year agreement begins on the date that the plan is activated.
