Call-related problems
SIM card error
SIM card malfunction or
damage.
Take the SIM card to your
service provider for testing.
The SIM card is inserted
improperly.
Insert the SIM card properly.
Dirt or dust on the SIM
card’s metal contacts.
Use a soft, dry cloth to
clean the SIM card’s metal
contacts.
Poor reception
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.
Move to a location where
you can receive proper
network signal.
The network is busy at the
current time (for example,
during peak times, there
may be too much network
traffic to handle additional
calls).
Avoid using the phone at
such times, or try again after
waiting a short time.
You are too far away from a
base station for your service
provider.
You can request a service
area map from your service
provider.
