Data allowances and usage information

Why does AT&T have a data usage allowance for internet customers?
This program is designed to help keep internet service affordable for our broad base of customers given the rapidly increasing volume of data-rich internet traffic.

What do you mean by data usage?
Usage includes all the data you receive (download) or send (upload). If you access the internet through your home network, wired or Wi-Fi, using any device (including smartphones), that will be included in your data usage.

This includes software updates, email notifications, and social media posts. Individual usage results may vary based on the applications you use and the content you access. For example, if your emails have large attachments, the usage for that application may exceed what we have estimated in the data calculator. 

For DSL, in some cases, AT&T is unable to measure your data usage due to system limitations. In that case, you will be unable to determine your usage using the data tracker, and AT&T will not charge you for usage over your data allowance.

What is a gigabyte?
A gigabyte measures the amount of data you send and receive over the network – not the amount of time spent connecting to the internet. A gigabyte (GB) is 1,073,741,824 bytes, 1,048,576 kilobytes, or 1024 megabytes.

Approximately 50,000 single-page emails without attachments, for example, would equal about 1GB. Watching an 80-minute movie in standard definition or about 20 minutes of a TV show or movie in high-definition each equals about 1GB.

What are the data allowances?
AT&T internet service data allowances include the following:
  • 150 Gigabytes (GB) per month for customers with DSL service.1
  • 250GB per month for customers with Fixed Wireless Internet service.
  • 1 Terabyte (TB) per month for internet speed tiers up to and including 768 Kilobits per second (Kbps) through 300 Megabits per second (Mbps).
  • Unlimited home internet data for customers with the internet 1000Mbps speed tier, combined bills for home internet and U-verse TV or DIRECTV as a benefit of bundling, or the $30 unlimited usage option. Learn more about unlimited home internet data.

I don’t know my current internet speed tier or plan name … how can I find out?
Your internet speed tier and plan name can be found by signing into myAT&T from your computer or mobile device.
  1. Go to your myAT&T account overview.
  2. Find and select one of the following to see your internet speed tier:
    • My Internet
    • My DSL Internet

Will spending a lot of time on the internet make me go over my allowance?
The types of activities performed matter more than the time spent online. For example, so-called data-rich activities, such as streaming video, may use more data than sending emails.

Help me understand more about what I can do within my allowance each month.
First, find your data allowance in the table below, then read down the column for details about how that number translates into monthly activities.

If I use Wi-Fi, does that count as usage?
If you access your residential internet over your Wi-Fi home network using any type of device (including smartphones and some home automation equipment), that counts as AT&T internet data usage. However, if you access the internet via a public or commercial Wi-Fi hotspot, that access does not count as usage. 

Can anyone who doesn’t live in my home affect my bandwidth usage?
That depends. AT&T Wi-Fi gateways are secured. If you have some other gateway or router and have not secured it, someone nearby with a computer or other Wi-Fi enabled device could access your home network, use your high-speed internet, and increase your usage. Common encryption protocols, such as Wireless Encryption Protocol (WEP) or Wi-Fi Protected Access (WPA), can provide additional security. Learn how to secure your AT&T-provided devices. Others can check their manufacturer's support website for help in securing their Wi-Fi gateway.

I have an AT&T MicroCell, which uses high-speed internet in my home to boost wireless voice and data signals. Will that wireless usage count against monthly usage allowance?
No, the wireless traffic from an AT&T MicroCell is not included in your AT&T Internet data usage allowance. To help ensure accurate billing, you should register your AT&T MicroCell account and residential AT&T Internet account at If you have Fixed Wireless Internet or internet service with another provider, you do not need to register your account, and MicroCell usage will count against your monthly usage allowance.

Will using wireless TV receivers count against my monthly usage allowance?
No – viewing standard video content through a wireless U-verse TV or DIRECTV receiver connecting to your Wi-Fi gateway won't count as data usage. Pay-per-view video, software updates, and DVR schedule data count as data usage.

Customers who subscribe to both services and pay for it on a single bill will receive unlimited home internet data. To combine bills at no additional cost, a customer should visit (Unlimited internet data is not available to DSL or Fixed Wireless Internet customers). 

Will using AT&T applications count toward my data usage?
Yes, using some TV, mobile, tablet, and wearable applications may generate a small amount of usage. Following is a partial list of U-verse TV and AT&T applications that use the internet and will have an impact on usage when connected to your AT&T home network:

  • Pay Per View
  • OnDemand
  • 4K programming

If I stream DIRECTV on my devices over my home Wi-Fi, will this count toward my data usage?
If you stream DIRECTV on your mobile device over your home internet service Wi-Fi connection, usage will count towards your home internet monthly data usage. 

Will using DIRECTV NOW count towards my data usage?
DIRECTV NOW is an over-the-top streaming service. All streaming over your home internet, wired or Wi-Fi, will count towards your home internet monthly data usage.

Will using SamKnows count toward my data usage?

Check and manage data usage

How do I measure the amount of data I’m using?
A variety of free tools and communications are available to help you monitor and manage your data usage at our internet usage page.

For example, you can learn which internet activities have the largest impact on usage. Other aids include the AT&T Data Calculator, the myAT&T app, instructional videos, the proactive email notifications we’ll send about your data usage, and ongoing customer communications pieces.

Sign in to myAT&T via the website or smartphone app to monitor usage and to view historical usage levels with a usage meter. This meter tracks all data uploaded and downloaded with internet-connected devices on your home network.
Is there anything else I need to know before looking over my personal usage?
A password is needed to access your information. This protects your confidential customer information. The sign-in is your AT&T primary account email address. For example, john The password is the same password you use to access your homepage and email account.

How often does AT&T update usage data?
Usage data is pulled from the network every 4 hours for most customers and at 15-minute increments for higher-usage customers.

Usage information for the first day of a new bill cycle may not be available for viewing until later on the first day of the new bill cycle. Time shown in the usage display is in terms of the GMT (Greenwich Mean Time) time zone which is behind the U.S. time zones. For example, if you are in the CST time zone (Central Standard Time), CST is 5 hours behind GMT. So when it is 10 a.m. CST, the time will be displayed as 3 p.m.

If I decide I want to start routinely checking on my usage, is anything available to make it simple?
You can view and manage your home internet usage through myAT&T. This portal also enables you to download your most recent AT&T bill, which also includes additional usage details.

What if I want to estimate my usage in the future? Is that possible?
Yes. We’re providing several tools to help. You can quickly estimate the amount of data your favorite activities use by visiting the AT&T Data Calculator. The calculator can also help estimate approximate monthly usage.

How do I know if I went over, or if I’m about to go over?
If you don't receive a notice from AT&T, it means you won't incur additional charges for exceeding the monthly data allowance.

To help advise you of your usage, we'll provide a total of seven notices before additional charges will affect the bill. Notices are sent at 100% usage in the first month, and 65%, 90% and 100% usage in subsequent months.   

Can you provide more information on how I’m notified about approaching or exceeding the data allowance?
You’ll receive an email notice during the first billing cycle in which you exceed the monthly data allowance, but you will not be charged. In the following billing cycle, you’ll receive notices any time usage reaches 65%, 90% and 100% of the allowance, but you will not be charged. During later billing cycles you’ll receive notices when usage reaches 65%, 90% and 100% of the allowance. 

Where will notifications about my usage be sent?
You’ll receive email notices about your home internet usage at the primary email address you set up when you registered for service. AT&T sends a letter by U.S. mail if we cannot reach you by email or do not have your email address.

Is there a way to check what I have as my primary email address? What if I need to change it?
Your email address can be found by signing into myAT&T.
  1. Go to Account overview.
  2. Find and select the My Internet or My DSL Internet section.
  3. Select Manage my plan under My Plan,
  4. Choose one of the following. If you have:
    • Internet service. Next to your plan name, select Plan details. Then in the My email address section, find the address marked primary.
    • DSL service. In the Email accounts section, the email on file should be marked as primary.

What happens if I exceed the allowance?
As data usage exceeds the additional allowance in a single bill cycle, you’ll receive another 50GB of data for $10 up to a maximum monthly overage charge of $100 for AT&T Internet or $200 for DSL and Fixed Wireless Internet.

If I go over my monthly data allowance, when will usage charges appear on my bill?
The usage measurement is based on your billing date. If usage charges are incurred they will be outlined on AT&T bills after usage takes place. Depending on your billing date and when you exceeded your data allowance in your billing cycle, it may take one to two billing cycles before charges appear on the bill. If you go over the monthly data allowance for a third time, charges for the additional data typically appear on the following month’s bill.

How do you know that your usage measurement is accurate?
A dedicated team of trained and specialized AT&T lab engineers thoroughly review and check the accuracy of our system on a regular basis.

Is AT&T implementing these data allowances to make customers pay more for the same service?
No. The monthly data allowances have been in place for all AT&T Internet customers since 2011. We anticipate that most customers will rarely go over their current monthly data allowance.
