system, you will see the roaming icon along with the text – Digital Roam – .
Roam on Other Digital Networks
When you’re roaming on digital networks, your call quality and security will be similar to the quality
you receive when making calls on the Nationwide Sprint Network. However, you may not be able to
access certain features, such as data services, depending on the available network.

your call is dropped in an area where you think Sprint service is available, turn your phone off and on
again to reconnect to the network.
