Here's my copy of the instructions from my provider. I assume you have
your unlock code from your provider:

"Before starting the process we have to give you warning. You have 5
tries, for the life of the phone, to enter this code. If you go beyond
the 5 tries your phone will be permanently locked to Cingular network.

If you get code error twice I do suggest you call us before going any
further. From within the US 1-800-331-0500 outside the US call

1. For the unlocking of a locked Sony Ericsson, no Simcard is required.

2. Turn on the handset. Display will indicate “Insert SIM.

3. Press the left Arrow () button.

4. Press the star (*) button twice.

5. Press the left Arrow () button again.

6. You will briefly see the message “Personalized with MNC2” or
“Personalized with MNC3”.

7. Wait approximately three seconds.

8. The display will indicate “Network” and a picture of a closed lock.

9. Press Select.

10. The display will indicate “Unlock (Net)5” and “NCK:”.

11. Enter the 16 digit NLCK4U code YOUR UNCOCK CODE HERE and press okay.

12. The handset will display “Network unlocked” and the display “Insert
SIM” appears.

13. The handset is successfully unlocked.
