If you just bought a Sony Ericsson XPERIA it can be good thing to check whether its locked to a carrier or not. The procedure to check if a Sony is simlocked is not shown in it´s manual and uses a special code sequence to enter a menu where this easily can be determined

With the phone powered on:

Open the dialer and enter the following sequence:

*#*#7378423#*#*

You will come to a new menu with some sub-menus

Choose the menu: SERVICE INFO.

Choose the menu: SIMLOCK.

In this menu you can see 5 rows:

[] Network
[] Network subset
[] Service provider
[] Corporate
[] SIM

If there is one or more rows marked by an “X” , that means that your Sony XPERIA is simlocked If all the rows are “empty” then your Sony XPERIA is locked to a carrier and you can change simcard in it as you wish. This method is universal at least for all phones in the XPERIA series.
