Account management & billing


There is no cost for the AT&T Locker application, which comes with 50GB of free* storage. By setting up AT&T Locker to upload or download on Wi-Fi networks only, you won’t be charged for data usage. If you access AT&T Locker on the AT&T cellular network, the app uses data on your wireless device. Uploading, downloading, or streaming content from your wireless device can use large amounts of data. This may lead to data overage charges.

*Data rates may apply for app download and usage.
