Network lock control key

Hi

 

I've moved from england to israel and tried to use a different sim in my Galaxy S2. The nuc code I've been sent from O2 doesn't seem to work.

 

Is there anything I can do?

The phone requests a network control lock code when I turn it on with the local sim inserted.

If you are sure you have entered the code correctly you must have been sent the wrong code. DO NOT keep trying the same (wrong) code or you will lock the phone out forever!!
I'd get back to O2 and request another code, using the unlocking form, and see if you get a different one back. What version of firmware do you have on the phone? You might be able to use an app off Play store if you root your phone.

You might have locked it now which will give you issues. If you can root you can try this app.... https://play.google.com/store/apps/details?id=eu.chainfire.sgs2simunlockcode&feature=search_result#?...
