Get details on the data that comes with your AT&T Prepaid phone or data plan.
AT&T Prepaid® phone plans come with either unlimited data or a data allowance for each plan cycle.
During periods of congestion, customers may experience reduced data speeds and increased latency as compared to other customers using the same cell site (Congestion-based Data Management).
Depending on your AT&T Prepaid unlimited plan, you may either always experience Congestion-based Data Management or experience it only after you have used a set amount of data in a billing period as outlined in your plan. Or you may have an unlimited plan with maximum data speeds (for example, data speeds limited to max 3Mbps and slowed to 1.5Mbps after a data usage threshold).
For customers on plans subject to a data usage threshold for triggering Congestion-based Data Management, we will notify you during your plan cycle when your usage reaches 75% of your threshold (for example, 16.5GB for plans with a 22GB threshold) so that you can adjust your usage to avoid network management practices that may result in slower data speeds.
AT&T Prepaid has some plans that provide an allotment of high-speed data, and once customers exceed their allotments of high-speed data during their plan cycle, they can continue to consume data at no extra charge but at significantly lower speeds when connected to the cellular network.
For example, if you use all of your high-speed data allotment on this type of plan, your service over the cellular network will transmit data at a maximum of 128Kbps for the remainder of your plan cycle.
We notify you when your usage reaches 75% and 100% of your data allotment.
You can purchase additional high-speed data for these plans. Sign in to your AT&T Prepaid account to check available data Add-Ons for your plan.
AT&T Prepaid data plans for tablets and hotspots come with an allotment of high-speed data. Once you have exhausted your data allotment, you can purchase a data add-on for an additional cost. Sign in to your AT&T Prepaid account to check available data Add-Ons for your plan.
We notify you when your usage reaches 75% and 100% of your data allotment.
