How to check simlock status
*#0606# and then press left soft-key, you will see strange characters, then text ("brak blokad"). If you see for example 260-02, it means the phone is locked to Era GSM. In older models you can use *#06# and see the same information after clicking on left key (you will see IMEI and software version).
