When receiving new alerts, your phone
notifies you by transmitting a unique tone,
vibrating, and displaying the alerts. There
is no additional charge to receive CMAS
alerts. Alerts may not be available while
you are on active calls, if you are outside
the T-Mobile coverage area, or because
of interference concerns. You cannot
forward or reply to CMAS alerts. Currently,
CMAS alerts will only be in English (no
other languages available). Occasionally, a
duplicate of a previously received alert may
display again. For more information and
FAQs, please go to t-mobile.com/CMAS.
