Roaming on Analog Networks
When you roam on analog networks, you will experience a
similar quality provided by other analog carriers today.
Although some features may be unavailable, you can still
make and receive calls and access voicemail. If you are
accustomed to network service, you may notice some of
the following differences when using analog service:
You are more likely to experience static, cross-talk,
fade-out, and dropped calls.
Some features which are standard on the network
available to you, such as call waiting and direct
international dialing, may be unavailable.
Though callers can leave voicemail messages while you
are roaming, you may not receive notification until you
return to the network available to you. (See "Checking
for Voicemail Messages While Roaming" on page 72.)
There are security and privacy risks (eavesdropping
and cloning) that exist with conventional analog
services today.
Your battery's charge will deplete more quickly and you
will need to recharge it more often when you use your
phone for analog roaming.
Note:
When using your phone in analog mode, the phone may feel warm.
This is normal for analog operation.
