No service indicator — Indicates your phone cannot find
a signal because you’re outside a service area. You
cannot make or receive calls. Wait for a signal or move
into an open area to try and find a signal. The no service
indicator always appears when you turn on your phone
and disappears once service is located.
Roam — Roaming occurs when you use your phone
outside your home area. While roaming, a wireless
provider other than yours handles your call, so the service
rate for the call may be higher than those made within
your home area. Please refer to information from your
Wireless Provider on roaming rates.
New Message — Indicates that you’ve received a new
text, page, or web alert message. You’re also notified by a
visual and audible alert.
Voice Mail — Indicates that you’ve received a new voice
mail.
1X Protocol — Indicates your phone is using the 1X

displays and the phone sounds an audible alert, which
indicates your phone is about to shut down.
