Troubleshooting

 

Your phone is set to work only with 
certain SIM cards. Check if you are 
using the correct operator SIM card.

 

You have entered your PIN or PIN2 
incorrectly.

Enter the correct PIN or PIN2 and 
select 

. See PIN on page 6.

You have entered your PIN or PIN2 
code incorrectly three times in a row.

To unblock, see SIM card lock on 
page 66.

 

Codes that you have entered do not 
match. When you want to change a 
security code, for example, your PIN, 
you have to confirm the new code. 
See SIM card lock on page 66.

Your phone is in flight mode. See Flight 
mode on page 59.

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. Please 
contact the nearest Sony Ericsson 
service location.

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 33.

 

You entered your personal unblocking 
key code (PUK) incorrectly 10 times 
in a row.
