Troubleshooting
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 the
network signal can be properly
received.
Avoid using the device at such
times, or try again after waiting
a short time.
You can request a service area
map from your service
provider.
