TIP
Become familiar with low coverage areas
where you live, commute, work, and play, so
you know when to expect signal strength
issues.
You are in an area that supports
UMTS services.
Your phone is on and a UMTS data
connection is active. You can make
and receive calls and transmit data
simultaneously.
Your phone is connected to a GPRS
(EDGE if available) network, but you
are not actively transmitting data.
You can still make or receive calls.
Your phone is on and a GPRS
(EDGE if available) data connection
is active. Your incoming calls may
not go through when you are
actively transmitting data. If you
make a call, the data transmission
is automatically interrupted, and
you must manually resume the
data connection when you end the
call.
