How to access your Sony Ericsson's hidden menu and check how many attempts it has remaining:
IMPORTANT: Do not retype the unlock code if you get an error message.
Turn on your Sony Ericsson without a SIM card inserted.
- Press the Home button once.
- Press the Back button twice.
- Press the Home button once.
- Press the Back button once.
- Press the Home button twice.
- Press the Back button once.
In summary, the sequence is as follows: 1-2-1-1-2-1. It doesn’t matter if nothing appears on screen. You have now accessed the service menu:
- [x] network 5
- [x] network subnet 5
- [x] service provider 5
- [x] sim 5
The number on the first line next to the word Network is the number of unlocking attempts your phone has remaining. If you see a 0, you will not be able to unlock your Sony Ericsson even if the unlock code provided is valid. This is why we recommend performing this check before making your request.
