Often a handset will prompt you for a code automatically when you enter a new SIM card but, if not, here are quick instructions to easily enter the unlock code you’ve ordered into your Sony Ericsson W890 handset:
1. Remove the SIM, then power on the handset.
2. Press left.
3. Press * twice.
4. Press left.
5. Select “yes”.
6. Enter the code.
7. Select “yes”.
That’s it – enjoy your freshly unlocked W890!
