TERMS RELATING TO YOUR DEVICE AND CONTENT
My Device Print this section | Print this page
You are responsible for all phones and other devices containing a SIM assigned to your account ("Devices"). Your Device must be compatible with, and not interfere with, our Services and must comply with all applicable laws, rules, and regulations. We may periodically program your Device remotely with system settings for roaming service, to direct your Device to use network services most appropriate for your typical usage, and other features that cannot be changed manually.
Devices purchased for use on AT&T's system are designed for use exclusively on AT&T's system ("Equipment"). You agree that you won't make any modifications to the Equipment or programming to enable the Equipment to operate on any other system. AT&T may, at its sole and absolute discretion, modify the programming to enable the operation of the Equipment on other systems.
If you bought a phone from AT&T, your phone may have been programmed with a SIM lock which will prevent the phone from operating with other compatible wireless telephone carriers' services. If you wish to use the SIM-locked phone with the service of another wireless telephone carrier, you must enter a numeric Unlock Code to unlock the phone. AT&T will provide the Unlock Code upon request to eligible current and former customers, provided that (1) the customer has completed a minimum of 90 days of active service with AT&T, is in good standing with AT&T and is current in his or her payments at the time of the request; (2) if applicable, any period of exclusivity associated with AT&T's sale of the handset has expired; and (3) AT&T has such code or can reasonably obtain it from the manufacturer. For phones sold with a Prepaid Plan, AT&T will provide the Unlock Code upon request to eligible current and former customers who provide a detailed receipt or other proof of purchase of the phone. iPhone and certain other devices are not eligible to be unlocked. For further details on eligibility requirements and for assistance on obtaining the Unlock Code for your handset, please call 1-800-331-0500 or visit an AT&T company store.
You are solely responsible for complying with U.S. Export Control laws and regulations and the import laws and regulations of foreign countries when traveling internationally with your Equipment.
