do the codes work?

[zeus68]

I have a nokia 3510 on UK orange. Do the automatic codes work or will it kill my phone? Has anyone tried them? It gives 7 codes do I need to put all 7 in the phone? Please help, it's work's phone and I don't want to mess it up but I need it unlocking to take other sims

I did not test. You cannot trash your phone by wrong codes, only if you enter codes 5x wrong, you need to unlock it with a cable solution like Griffin, UFS2, etc...

If Code Nr. 1 works, you do not need other codes. If it does not work (eg Prepaid) use Code 7. In rare cases you need Code 5.

for all non-us phones - always use code 7. (code 7 only, not all 7)..
