Troubleshooting
Some problems require you to call your network operator, but you can correct most
problems yourself. Remove the SIM card before handing your phone in for repair. For more
support, go to www.sonyericsson.com/support.
Restart your phone every day to free memory. Do a Master reset if you are having problems with
memory capacity or if the phone is working slowly.

My phone is not working as expected

If you experience problems with your phone, check these tips before you try anything else:
•Restart your phone.
•Remove and re-insert the SIM card. Then restart your phone.
•Force a restart of the phone if the phone hangs and can't be restarted normally.
•Update your phone software. Updating your phone ensures optimal performance and
provides the latest enhancements.
•Reset your phone.
Be patient while resetting your phone. Restarting the phone during a reset procedure may
damage the phone permanently.

Master reset

If you experience problems with your phone, such as screen flickering, screen freezing or
navigation problems, you should reset the phone.
To reset the phone
•Select Menu > Settings > General > Master reset and select an option.
Reset settings resets all changes that you have made in your phone to default. Reset all deletes
all user data such as contacts, messages, pictures and sounds in your phone.

No battery charging icon appears when phone starts charging

It may take a few minutes before the battery icon appears on the screen.

No network coverage

•Your phone is in Flight mode. Make sure Flight mode is turned off.
•Your phone is not receiving any network signal, or the received signal is too weak. Contact
your network operator and make sure that the network has coverage where you are.
•The SIM card is not working properly. Insert your SIM card in another phone. If this works,
it is probably your phone that is causing the problem. In this case, contact the nearest
Sony Ericsson service center.

Emergency calls only

You are within range of a network, but you are not allowed to use it. However, in an
emergency, some network operators allow you to call the international emergency number
112. See Emergency calls on page 18 for more information.

SIM locked

You have entered your PIN incorrectly three times in a row. To unlock the phone, you need
the PUK (Personal Unblocking Key) provided by your operator.
