Troubleshooting

Problem
Call-related problems
SIM card error
Poor reception
Possible causes
SIM card malfunction or
damage.
The SIM card is inserted
improperly.
Dirt or dust on the SIM
card's metal contacts.
The network signal is too
weak at your current
location, for example, in a
basement or near a tall
building. Wireless
transmissions can not
effectively reach it.
The network is busy at the
current time (for example,
during peak times, there
may be too much network
traffic to handle additional
calls).
You are too far away from a
base station for your service
provider.
Possible solutions
Take the SIM card to your
service provider for testing.
Insert the SIM card properly.
Use a soft, dry cloth to
clean the SIM card's metal
contacts.
Move to a location where
you can receive proper
network signal.
Avoid using the phone at
such times, or try again after
waiting a short time.
You can request a service
area map from your service
provider.
