Roaming
Calls made outside of your Home Service Area and outside of
the Sprint PCS Network are "roaming" calls. Your
Sprint PCS phone is specifically designed and engineered to
work only on the Sprint PCS Network. It works on other CDMA
PCS providers' systems only when a roaming agreement is in
place between Sprint PCS and the other providers. If your
Sprint PCS Phone is a dual-mode phone, it works on both a
CDMA PCS provider's system (in addition to the Sprint PCS
Network) and a wireless analog telecommunications
provider's system only when roaming agreements are in place
between Sprint PCS and the other providers. If we do not have
a roaming agreement in place, you may be able to place
roaming calls "manually" by using a valid credit card.
Certain features are not available when roaming. Roaming
rates may be different from and higher than the rates you pay
for calls within your Sprint PCS Home Service Area and on the
Sprint PCS Network. Roaming charges are invoiced according
to the practices of the roaming service provider. When
roaming, you are subject to the limitation of liability
provisions and other applicable rules imposed by the roaming
service provider on its own subscribers or on roamers.
Interruption of Service
We may give credit for a continuous interruption of Services
for more than 24 hours on a case-by-case basis. Interruptions
caused by your negligent or willful actions, or by failure of
equipment or service not provided by us, or by causes beyond
our reasonable control, do not qualify for credit. We may
provide you with an airtime credit of one minute for a call that
is disconnected because of transmission limitations caused by
atmospheric, geographic or topographic conditions and that
you redial within one minute of disconnection. You must
