Get info about our 4GB plan

You’ll have 1 plan, but every line on your account gets a 4GB data allowance.


What’s included with the AT&T 4GB plan

Enjoy these features with your 4GBSM plan:1
  • Unlimited talk and text in the U.S., Mexico, and Canada
  • 4GB per line data limit in the U.S., Mexico, and Canada
  • Standard-definition (SD) video streaming
  • Tethering and mobile hotspot data for eligible devices
  • AT&T ActiveArmorSM security (spam and fraud call blocking)
  • $10 monthly discount per line when you sign up for paperless billing and AutoPay (discount starts within 2 bill periods)
  • Unlimited texting from the U.S. to over 120 countries
Good to know: If a line uses more than 4GB of data in a month, we’ll automatically add overage data in increments of 2GB and charge you $10 for each 2GB added to the line. Plus, the 4GB plan doesn’t include 5G access or Rollover Data®. Any unused data, including overage data, is forfeited at the end of each billing period.
